の外周にワークを支持することができる。(Operation) When the drive device moves the cam pin parallel to the support shaft in the direction away from the cam groove, the cam pin separates from the slope forming the cam groove of the movable piece, so that the movable piece is released from the constraint by the cam pin and the spline is released. Some rotation in the circumferential direction is allowed on the shaft. Therefore, it becomes possible to align the teeth formed on the movable piece with the teeth formed on the spline shaft, and if they are aligned, the spline hole of the workpiece is smoothly fitted to the teeth of the spline shaft and the teeth of the movable piece. The workpieces can be supported on their outer circumferences.

As a result, the teeth formed on the movable piece move in the circumferential direction, and the tooth surface of the movable piece and the tooth surface of the spline shaft are pressed against the tooth surface of the spline hole provided in the work from the circumferential direction to move the work. Fix it.
