The compression force of the bolt 30 and the bolt 30 acts as the force of the fastening points 5 and 6 at the axial force generating points 123 and 124 while the compression is in progress. There is no loss of axial force. That is, the axial force generating point portions 123 and 124 transmit only the pure axial force to the bolt 30 on the same axial line, so that the elastic repulsion force is restored by the inhibition of rotation of the spring washer 10, so that the frictional force with the nut 40 is increased, so that the nut ( 40 or the loosening of the bolt 30 is further suppressed.

In this case, the sawtooth protrusion 125 is formed at a portion other than the corresponding axial force generating point portion 123 or 124. Serrated protrusions 125 have the same projecting height along the circumferential direction. Serrated protrusion 125 is a linear linear compression with the fastening 6 when the spring washer 10 receives the axial force according to the compression tightening of the nut (40). Therefore, when the nut 40 is fastened, the toothed protrusion 125 of the spring washer 10 has the effect of suppressing the rotational force of the spring washer 10 and transmitting only pure axial force to the bolt 30.

In addition, the spring washer 10, as shown in Figure 5a and 5b may be further configured to read the metering dividing holes (121a, 122a) in the body 12 to examine the amount of loosening with the probe rod (200). The metering dividing holes 121a and 122a are formed in the cut surfaces 121 and 122 (see Fig. 5C). The metering split holes 121a and 122a form one circle in a semicircle when their centers coincide with each other.

Thereafter, the metering dividing holes 121a and 122a are deviated from each other by the amount of repulsion deformation of the body 12 according to the amount of loosening of the nut 40.

Enter. If the nut 40 is loosened, the probe dividing holes 121a and 122a of the spring washer 10 do not maintain the circle, and thus the probe rod 200 is not inserted into the probe dividing holes 121a and 122a. The loosening of the nut 40 or the spring washer 10 is confirmed.

Elastic ring 14 is inserted into the ring groove 126 formed on one surface of the body 12 is installed. The cross section of the ring groove 126 is not limited to a specific shape, but a triangular cross section is preferable so that the elastic ring 14 is not separated after being inserted into the ring groove 126 as in the present embodiment.

The large axial force is generated to further suppress the loosening of the nut 40.
