Claims

[Scope of utility model registration request]

An annular ring disposed between the bar and the cylindrical joint body into which it is inserted, moves together with the bar as the bar moves in the pulling direction, and is formed at a predetermined position on the inner peripheral surface of the joint body. A plurality of annular retaining member elements each having a notched portion that is pressed against the tapered surface and biting into the bar material are arranged in the axial direction and at least on one end side of the notched circular portion of the retaining member element and the retaining member adjacent thereto. A member for preventing a bar from coming off from a joint body, characterized in that the missing circular portions of the elements are mutually staggered and fixed in parallel so that they can be expanded and contracted.
