Document Type and Number:
Japanese Patent JP6715455
Kind Code:
B2
Abstract:
In this male screw body, a male-screw-body-side coupling region is formed that has a non-circular shaped cross section when viewed from the axial direction. A washer (coupling member) has a through hole that is non-circular, and engages the outer peripheral direction of the male-screw-body-side coupling region. Furthermore, the washer is provided with an engagement mechanism that engages a female screw body in the peripheral direction. As a result, rotation of screw body in a specific direction is reliably prevented by means of a simple structure.
