Claims

[Scope of utility model registration request]

A thin groove is formed on the outer surface of the threaded portion of the bolt along the axial direction of the bolt, and a thin groove parallel to the thin groove of the bolt is formed on the outer surface of the threaded portion of the nut, and a split ring-shaped member is formed. On the circumference of the ring inclined along the inclination of the thread of the bolt,
A locking member is formed by erecting a pin that fits into the narrow grooves of the bolt and nut, and when the nut is screwed onto the bolt and the narrow grooves of both match, the locking member is inserted into its ring portion. A structure for preventing loosening of a nut, characterized in that the pin is fitted into the valley of the thread of the bolt, and the pin is fitted into the matched narrow groove.
