Claims

[Scope of utility model registration request]

A detent nut consisting of a nut body and a detent ring made of an elastic material, the nut body having a threaded part with a female thread carved inside and a return protruding from the end face of the threaded part. The detent ring holding part has a recess that opens inward by the detent ring holding part and the threaded part, and the recess has a recess that opens inward. A retaining ring is loosely fitted, and the inner diameter of the retaining ring is approximately equal to the root diameter of the internal thread of the threaded section at the end surface closest to the threaded section;
A detent nut characterized in that the diameter of the detent becomes smaller than the root diameter as it approaches the end face farthest from the threaded portion.
