It has a first strong elongation stress portion capable of covering a part or all of at least one ligament, and the middle strength elongation stress portion is a first middle strength elongation disposed around the entire circumference of the first elongation stress portion. An elbow supporter having a stress portion is known (for example, see Patent Document 3).
Moreover, as a cylindrical supporter which can obtain a good fit over the entire wearing part without causing the wearer to feel a sense of tension or lack of support, the cylindrical supporter is knitted using at least two types of elastic yarns. An elastic yarn having a larger elastic force than the elastic yarn knitted in the second region is knitted in the first region covering the elbow joint and including the first region and the second region. A hollow cylindrical supporter is known (for example, see Patent Document 4).

[Elbow supporter]
The elbow supporter of the present embodiment is attached to a portion including the elbow of the arm, and has an elbow head surface portion that supports the elbow (elbow head) side surface (the outer surface of the arm) and an inner surface of the elbow (the inner surface of the arm). Supporting elbow inner surface, upper arm side outer surface portion supporting the upper arm side outer surface with respect to the arm elbow, upper arm side inner surface portion supporting the upper arm side inner surface, forearm supporting the forearm side outer surface with respect to the arm elbow Equipped with a cylindrical supporter body including a side outer surface part and a forearm side inner surface part that supports the inner surface on the forearm side, the elastic modulus at 80% elongation in the axial direction of the supporter body is A, the elbow head surface part is A, and the elbow inner surface part Where B is the upper arm side outer surface portion, C is the upper arm side inner surface portion, D is the forearm side outer surface portion, and F is the forearm side inner surface portion. It is a supporter.

Since the elbow supporter of the present embodiment has the above-described configuration, it is excellent in a feeling of fixation with respect to the elbow joint and ease of bending and stretching operation of the elbow joint.

Hereinafter, the effects described above (fixed feeling with respect to the elbow joint and ease of bending and extending operation of the elbow joint) will be described in more detail.
According to the study by the present inventors, it has been found that there is a positive correlation between the elastic modulus of the elbow supporter and the feeling of fixation of the elbow supporter to the arm. That is, the higher the elastic modulus of the elbow supporter, the higher the pressure applied to the arm (that is, the stronger the tightening force to the arm), and as a result, the wearer feels the fixation to the arm. It was found that the feeling improved.
Further, as a result of the study by the present inventors, the axial elastic modulus B of the inner surface of the elbow is determined as the elbow inner surface portion with respect to the elastic modulus at 80% elongation in the axial direction of the cylindrical supporter body (hereinafter also referred to as the axial elastic modulus) It has been found that the fixation feeling to the elbow joint is effectively improved by setting it to 0.7 times or more of the axial elastic modulus A of the head surface portion (that is, satisfying the formula (1)).

On the other hand, there is a negative correlation between the elastic modulus of the elbow supporter and the elongation of the elbow supporter.
In this regard, in the elbow supporter of the present embodiment, the axial elastic modulus D of the upper arm side inner surface portion is smaller than the axial elastic modulus C of the upper arm outer surface portion, and the axial elastic modulus F of the forearm side inner surface portion. Is smaller than the axial elastic modulus E of the outer surface on the forearm side (that is, by satisfying the equations (2) and (3)), the upper arm side inner surface portion and the forearm side inner surface when the elbow joint is bent Since the extension of the part is ensured, the ease of bending and extending the elbow joint is improved. More specifically, the upper arm side inner surface of the arm is a surface that has a higher body fat percentage than the upper arm side outer surface and the forearm side outer surface of the arm and is located on the inner side when the elbow joint is bent. For this reason, the upper arm side inner surface portion and the forearm side inner surface portion are required to be stretched during the bending operation of the elbow joint. Therefore, in the present embodiment, the axial elastic modulus D of the upper arm side inner surface portion and the axial elastic modulus F of the forearm side inner surface portion are respectively set as the axial elastic modulus C of the upper arm side outer surface portion and the axis of the forearm side outer surface portion. By making it lower than the directional elastic modulus E, the elongation of the upper arm side inner surface portion and the forearm side inner surface portion with respect to the bending of the elbow (elbow joint) is ensured, and as a result, the ease of bending and extending the elbow joint is improved.

In the present specification, the axial elastic modulus A of the elbow head surface portion is a measurement width having the center position of the elbow head surface portion (that is, the center in the circumferential direction and the center in the axial direction) as the measurement center. It means a value measured for a range of 15 mm (ie, circumferential length).
An axial elastic modulus B of the elbow inner surface, an axial elastic modulus C of the upper arm side outer surface, an axial elastic modulus D of the upper arm inner surface, an axial elastic modulus E of the forearm outer surface, and an axial direction of the forearm inner surface The same applies to each of the elastic modulus F.

In this specification, the “axial elastic modulus” (80% elastic modulus in the axial direction) is measured by a tensile test under the conditions of a grip width of 15 mm, a grip interval of 15 mm, and a tensile load of 20 N. Here, the direction of the tensile load is the axial direction of the supporter body.
In the tensile test for measuring the axial elastic modulus, a part of the elbow supporter is fixed to a tensile tester with a grip width of 15 mm and a grip interval of 15 mm, and stretched by pulling at a tensile speed of 15 mm / min. The elastic modulus (tensile stress) at the time of% elongation is read and used as a measured value.
In addition, when it is difficult to carry out the tensile test on a part of the elbow supporter, a 30 mm square test piece may be cut out from the elbow supporter and may be carried out on the cut out test piece. .

The number of tests is five, and an average value is obtained from three measurement values excluding the maximum value and the minimum value from the five measurement values, and this average value is adopted as the “axial elastic modulus”.
As a tensile test apparatus, a general tensile tester can be used. For example, an autograph “AGS-X 1kN” manufactured by Shimadzu Corporation can be used.

However, the structure in other regions is appropriately selected so that the axial elastic modulus EC is 5 to 50 times greater than at least one of the axial elastic modulus EE1 and the axial elastic modulus EE2.

The uneven knitted fabric region preferably includes a repeated knitting structure of tack.
Here, the tuck repetitive knitting means a knitting method in which tuck knitting is repeated.
When the uneven knitted fabric region includes a repeated knitting structure of tack, it becomes easier to adjust stretchability.

The uneven knitted fabric in the uneven knitted fabric region preferably includes a float knitted structure.
The float knitted structure in the uneven knitted fabric is easier to expand and contract than the knitted structures other than the float knitted structure. The reason why the uneven knitted fabric including the float knitted structure is soft is thought to be that the allowance for extension (ie, unevenness) remains in the float knitted structure in the uneven knitted fabric even when the uneven knitted fabric region is stretched during wearing. This stretch gives a soft feel when touching the skin. Moreover, it is preferable to form an uneven knitted fabric by arranging a float knitted structure also from the viewpoint of easy manufacture of the uneven knitted fabric.
The uneven knitted fabric in the uneven knitted fabric region is preferably knitted with elastic yarns, and the uneven knitted fabric is more preferably an uneven knitted fabric including a float knitted structure using elastic yarns. By using the elastic yarn, the uneven knitted fabric can be made softer.
Examples of the elastic yarn include polyurethane, polyolefin-based elastomer, natural rubber, and silicone. Among these, polyurethane, polyolefin elastomer, and natural rubber are preferable from the viewpoint of more excellent elasticity.

  From the viewpoint of excellent manufacturability when the elbow joint supporter is integrally manufactured by circular knitting, it is preferable to arrange a float knitting structure in the axial direction.

Moreover, it is preferable that an uneven | corrugated knitted fabric area | region has an elongate recessed part.
Needless to say, the long shape here is the shape of a recess in plan view.
Of the concavo-convex knitted fabric region, the bottom portion of the concave portion has the property of being easily stretched. For this reason, the uneven knitted fabric area | region which has an elongate recessed part has the property of extending easily in the width direction of this recessed part. Therefore, since the uneven knitted fabric region has the elongated concave portion, the entire uneven knitted fabric region is easily stretched, so that the operation followability is further improved.

The uneven knitted fabric region preferably has a plurality of elongated recesses.
The uneven knitted fabric region has a plurality of elongated recesses, and each of the plurality of recesses is preferably substantially parallel to the circumferential direction of the cylindrical elbow joint supporter. .
In this case, the width direction of the elongated recess corresponds to the axial direction of the elbow joint supporter. For this reason, since the uneven knitted fabric region becomes easy to extend in the axial direction of the supporter portion for the elbow joint, the operation followability is further improved.

  In addition, the fact that the uneven knitted fabric region has a plurality of elongated recesses having the length direction is also advantageous in that it is excellent in manufacturability when the elbow joint supporter is manufactured by circular knitting. Specifically, when the elbow joint supporter part is manufactured by circular knitting, one or more circumferential stitches are knitted by float knitting to knit the elongated recess (that is, the length direction thereof is the elbow). It is possible to easily manufacture a long concave portion that is substantially parallel to the circumferential direction of the joint supporter.
