ABSTRACT:
To provide a chuck device for preventing the loosening of the fastening condition, a plurality of claws inserted into a hole provided at an end of a body are opened, closed and slid by the rotation of a rotary sleeve and a tool is clamped by means of the claws. A coating that is hard and has a low frictional coefficient as much as possible is applied to an inner surface of the hole.
