Claims

[Claims for Utility Model Registration] An elastic, occluded ring body accommodated in a space surrounded by a tapered surface of the joint body is pushed and expanded by a rod inserted into the joint body. When the bar holding the ring body is pulled out, the ring body is pressed by the tapered surface to reduce its diameter and is pressed against the bar. In this case, between the two ends of the ring body that sandwich the missing circular part,
1. A member for preventing a bar material from coming out of a joint, characterized in that an elastic member is interposed to bias the ring body in a diametrical direction when the ring body is held in an externally fitted manner on the bar material.
