, That is, an inclined surface that is gently inclined toward one direction of the seating surface 3. The inclination angle of the seat surface 3, that is, the seat angle α is preferably about 1 degree. For example, outer diameter 30m
In the washer for M16 nut having an inner diameter of 19 mm and an inner diameter of 19 mm, the inclination is preferably such that the maximum thickness is 3 mm and the minimum thickness is 2 mm. Further, it is preferable to set the inclination direction of the inclined surface so that the opening of the elongated hole 2 becomes thinnest.

When the nut B is attached to the lower surface of the nut B and strongly tightened with a predetermined torque toward the member C to be tightened, the nut B is forced into an inclined posture along the inclined seat surface 3 of the washer A as shown in FIG. To settle. In this state, as shown by the arrow in FIG. 5, the screw hole on the upper slope side and the screw hole on the lower slope side of the nut B press the side surface of the bolt in the cutting direction. The engagement of the screws of the bolt D is firmly locked to prevent the nut B from becoming loose.
