ットの脱落に至る可能性があった。Generally, when vibration, thermal expansion and contraction are repeatedly applied to the tightening portion, the material of the fastening portion expands and contracts, wears, etc., and the fastening force of the bolts and nuts decreases. For this reason, when using a spring washer, the frictional force that stops the rotation of the bolts and nuts is reduced, and the bolts and nuts may turn in a loosening direction, which may eventually lead to the bolts and nuts falling off. .

知できる。EXAMPLES Examples of the present invention will be described below. FIG. 1 shows an example in which a cap (4) of the present invention is covered and a hexagon socket head cap bolt (3) [hereinafter referred to as bolt (3)] is prevented from loosening. The object to be fastened (1) is fastened to the main body (2) by bolts (3). After tightening the bolts (3) sufficiently, the cap (4) is driven in. The outer protrusion (4a) of the cap is press fitted into the counterbore (1a). Further, since the inner protrusion (4b) of the cap is fitted into the side surface of the bolt (3) in a press-fitted state, the loosening of the bolt is stopped. FIG. 2 is a plan view of FIG. Bolt-side outer protrusion (4a) and bolt-side inner protrusion (4b)
If the bolts (3) are arranged so as to be displaced as shown in the figure, there is no problem in mounting because the cap is elastic even if the bolt (3) is slightly eccentric with the spot facing hole (1a) due to machining tolerance. . A hole (4c) is formed in the upper portion of the cap (4) for tightening and removing the bolt (3). The cap (4) comes off together with the bolt (3) when the bolt (3) is removed. FIG. 3 shows a plan view of another embodiment,
FIG. 4 shows a sectional view thereof. In the present invention, the outer protrusion (4
A) is made sharper and the bolts are prevented from loosening more reliably. Further, the inner protrusion (4b) is fitted into the groove (3a) of the bolt (3) to ensure the locking. In this case, the outer protrusions (4a) may be arranged continuously or may be formed by knurling or the like. 5 and 6 show an embodiment applied to a hexagonal nut, FIG. 5 is a plan view and FIG. 6 is a sectional view. The cap (4) is provided with an outer protrusion (4a) press-fitted into the counterbore hole (1a). Further, an inner protrusion (4b) for restricting the movement of the three sides of the hexagon nut is provided. After the nut (3) is sufficiently tightened, if the inner protrusion (4b) is driven in alignment with the three sides of the nut, the rotation of the nut is restricted. In this case, the same effect can be obtained by using a hexagon bolt instead of the hexagon nut. When removing bolts and nuts, it is necessary to remove the cap in advance. FIG. 7 shows another embodiment in which the cap of the present invention can be used even when there is no counterbore hole. The press washer portion (5b) of the fixed washer (5) is driven into the bolt hole (1b) of the object to be fastened (1) in a press-fitted state to prevent the fixed washer (5) from turning. The fixed washer (5) is provided with a counterbore hole (5a) for a bolt at the center thereof. If the cap (4) is driven in after the bolt (3) is sufficiently tightened, the loosening of the bolt can be stopped as in the above-described example. Although various embodiments have been described above, it goes without saying that the present invention can be implemented by combining the respective methods. Further, it can be seen that this cap can be easily manufactured by a method such as press working, header working, and sintering.
