<p><P>PROBLEM TO BE SOLVED: To provide a retaining ring mechanism with which a structure for preventing entanglement can be provided in a simple assembling process and the structure for preventing entanglement can be reused. <P>SOLUTION: A retaining ring mechanism 10 to be mounted on an annular groove to regulate movement of a prescribed member comprises a ring member 20 formed to have a separated portion in a circumferential direction and to be inserted into the groove, and a lever member 30 mounted on the ring member 20. The ring member 20 has a first notch formed by notching an inner peripheral side near a first open end and a second notch formed by notching an inner peripheral side near a second open end. The lever member 30 includes a base part, a shaft part disposed on the base part and connected to the first notch so as to allow the lever member 30 to rotate radially inside the ring member, and an protruding part disposed in the base part and detachably inserted into the second notch by rotation of the lever member 30. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
