ワッシャ裏面４にナットが入る段差を付け、ワッシャ表面５にナットが回転しながらはまり込む凹凸をつける事により、ナットが緩み方向に動かないようにした。
ワッシャの両面とも〔図１〕の形状にしても同等の効果が得られる。尚、六角以外のナット、四角等ではその角度にワッシャ表裏の形状を変える。A step where the nut enters the back surface 4 of the washer is provided, and an irregularity that the nut is inserted while rotating the washer surface 5 is provided so that the nut does not move in the loosening direction.
The same effect can be obtained even if both sides of the washer are shaped as shown in FIG. For nuts other than hexagons, squares, etc., change the washer front and back shapes to that angle.
