In the chuck mechanism for attaching the wave stopper member to the rotating shaft by the locking body, the rotating shaft is provided with a plurality of holes drilled through the inner circumferential end of the locking body in the direction of its center line. A movably installed opening member is provided, and when the opening member is moved in the direction of the center line against the spring force of the spring member when the wave stopper member is attached to and detached from the rotating shaft, the opening member is moved. The wall around the hole of the member engages with the inner end peripheral wall of the locking body, and the locking body is moved in the radial direction of the rotating shaft, thereby reducing the inner diameter between the locking bodies. is thicker (widener) than the outer diameter of the wave stopper member. （２）前記錠止体は、前記回転軸の管壁に穿設した穴に
