The collet is axially protruded and coaxially supported by a rotating body, and an actuation rod is fitted into the axis of the rotating body and the collet so as to be movable in the axial direction, and the actuation rod faces the tapered surface of the collet. A collect chuck characterized in that a tapered shaft corresponding to the tapered surface is formed at the rod portion.
