PROBLEM TO BE SOLVED: To provide a simple-structure tool chuck capable of easily adjusting a spring preload and improving torque transmission.SOLUTION: A body 10 includes a shaft part having a center hole opened on the machine tool side and a sleeve part having a guide hole opened on the tool side where the shaft part is axially extended. The guide hole is separated from the hole in the shaft part by a radial partition. A housing body 20 is provided with a cylindrical guide part put through the guide hole in the sleeve part in an axially movable manner. Preferably, the housing body 20 is put through an axial through-hole of the radial partition and secured via an anchor 30 capable of adjusting a spring preload through a hole in the body 10. |
