Is formed.

  FIG. 10 shows a configuration in which the protective device divided bodies 24 integrally formed for several pieces 2 are connected to each other to be elongated.

  At one end of each protective device divided body 24, a projecting piece 25 extending in the same plane as the side plate lower end part 7 is extended, and a shaft part 26 facing left and right is integrally formed on the projecting piece 25. . A rearward projecting piece 28 is formed on the other end of each protective device divided body 24 from the side plate lower end portion 7 to the left and right outside via a stepped portion 27, and the projecting piece 28 is provided with a circular hole 29. ing. The front and rear projecting pieces 25 and 28 have flexibility in the left-right direction (plate thickness direction).

  By inserting the shaft portion 26 of the front projecting piece 25 into the hole 29 of the rear projecting piece 28 while bending the front and rear projecting pieces 25, 28, the front and rear protective device divided bodies 24 are connected to each other. The The shaft portion 26 is rotatably engaged in the hole portion 29. The shaft portion 26 and the hole portion 29 constitute a hinge, and each piece 2 can be bent inwardly (in the protruding direction of the side plate portion 7) together with the other thin hinge 3 in the middle.

  It is also possible to eliminate the front protruding piece 25 and provide a shaft portion on the front end side of the side plate lower end portion 7. Further, in the configuration of FIG. 10, the shaft portion 26 can be provided in the rearward projecting piece 28 in the left-right inward direction, and the hole portion 29 can be provided in the front projecting piece 25. In the example of FIG. 10, the number of pieces 2 of each protective device division body 24 is three, but this is only an example, and the number of pieces 2 may be, for example, 10 or more.

  FIGS. 11 to 14 show an embodiment of the harness protector 30 having a structure that regulates the inward bending angle to be substantially constant while preventing outward (reverse) warping of each piece 2 of the harness protector 1. The form is shown.

  11 and 13 show a part of the harness protector 30, and a bending angle adjusting (suppressing or restricting) member 32 is freely rotatable via a thin hinge 31 at the lower end of the side plate portion 6 on one side of the piece 2. Is provided. The plurality of pieces 2, the intermediate hinge 3, and the bending angle adjusting member 32 are collectively referred to as a harness protector 30.

The bending angle adjusting member 32 prevents the harness protector 30 from dancing when moving, and enables a smooth bending advance / retract operation (extension / contraction operation).

  For example, by setting the inclination angle of the inclined surface 34a of the wedge-shaped stopper wall 34 in various ways and selectively using it in the harness protector 1 in FIG. 1, the harness protector 1 is required depending on the use form. It can be bent at a bending angle.

  In the example of FIG. 11, the bending angle adjusting member 32 and the piece 2 are integrally formed. However, in FIG. 12, locking frame pieces 35 are provided on both the left and right sides of the substrate portion 33, and both side plates of the piece 2 of FIG. The bending angle adjusting member 32 may be formed separately from the piece 2 by providing the locking projection 36 on the portion 6. As the locking means, a protruding piece having a locking projection may be provided instead of the locking frame piece 35, and a recess or a hole may be provided in the side plate portion 6 instead of the locking projection 36.

  The shape of the bending angle adjusting member 32 is not limited to the above shape. For example, a locking frame piece (35) is provided directly on the left and right ends of the wedge-shaped stopper wall 34, and the locking frame piece 35 is attached to the outer surface of the side plate portion 6 It is also possible to engage with the engaging protrusion (36) on the inner surface, and the shape of the bending angle adjusting member 32 can be appropriately set as necessary.
