シヤである。[Scope of Claim for Utility Model Registration] This invention relates to a locking nut and washer for a vault. A planar flange is provided on one side of the circular inner diameter portion to prevent co-rotation, and a flange is also provided on the 180° opposite side, and an L-shaped flange is provided that is bent into an L shape. Use a plate slightly thinner than the pitch spacing. For the elbow that tightens the bolt, first place the L-shaped brim on the nut side, and rotate the flat brim of the washer along the trough of the screw until it reaches the closing part. , Next, when tightening the nut as usual, the L-shaped brim of the washer interferes with the tapered part of the nut at the tightening part, causing the washer to rotate a little, but the flat brim of the washer does not touch the screw. When the rotation stops when it reaches the lead angle of , and there is no co-rotation, the taper part of the nut strongly interferes with the L-shaped brim on the 180° opposite side at the same elbow due to the wedge action, and it automatically moves in the direction of the center of the bolt. When stress is applied to the bolt and it is tightened even more strongly, stress is also applied to the flat brim side of the nut in the direction of the center of the bolt, tightening the bolt from both sides, which increases the locking effect. This is a locking nut and washer that is characterized by the following features:
