Claims

[Claims for Utility Model Registration] A substantially cylindrical workpiece having a through hole at one end passing through the axis of the workpiece and extending in a direction perpendicular to the axis is laid down and its peripheral body is used to receive the workpiece. The other end of the workpiece is held rotatably around the axis by the workpiece pressing part while being pressed in the axial direction. In a rotating device for a substantially cylindrical workpiece, the workpiece clamping unit rotationally drives one end of the workpiece while being clamped by a workpiece clamping unit through the through hole, the workpiece clamping unit including (a) a clamp body; and (b) an axis about the clamp body. (c) a fixed pin with a flange that is fixed to the clamp body, extends in a direction perpendicular to the axis, and can be inserted from one end of the through hole; (d) (e) a movable pin with a flang that is held movably in the clamp body so as to be movable in the clamp body so as to face the fixed pin and can be inserted into the other end of the through hole; The fixed pin and the movable pin are each provided with an engaged portion and an engaged portion that engage with each other when the movable pin is in an advanced state, and the engaged portion and the engaged portion are respectively provided. The distance between the flanges of the fixed pin and the movable pin is set in the through hole so that one end of the workpiece can freely slide along the longitudinal direction of the fixed pin and the movable pin in the engaged state. A clamping device for a rotating device for a substantially cylindrical workpiece, characterized in that the length is set larger than the length dimension.
