Description of the Related Art Conventionally, a C-shaped retaining ring has been used to attach a rotor to a body of a lock or the like, and the diameter of the retaining ring is reduced to fit the lock body into the inner surface of the lock body. The retaining ring was fitted in the annular receiving groove provided in the. However, in order to seal the door, etc., the stopper on the lock side and the receiving part on the fixed frame side must be firmly adhered to each other, and as a reaction, a considerably large rotational moment acts on the rotor. ing.

では、一段と強まった。Rotational moment acts on the rotor by the offset weight of the stopper plate with respect to the locking shaft or the offset weight of the locking rod interlocking with the stopper plate. The rotating moment has a reduced diameter with respect to the retaining ring that contacts the rotor,
Since it acts as an external force to distort and deform, there were quite a few accidents where the retaining ring came off the annular receiving groove. This tendency is further enhanced under the use condition where a single or continuous vibration or impact is applied.
