SUMMARY OF THE INVENTION The present invention is designed to insert a handle part of a tool such as an end mill or a drill into a collet, and fit the collet into a collet fitting hole provided in a device body of an industrial robot or the like to fit the collet. A tool mounting mechanism configured to reduce the diameter of the collet on the inner peripheral surface of the hole to grip the tool, and perform deburring or chamfering with the tool, wherein a spherical receiving hole is formed on the peripheral surface of the collet. By inserting a collet into the collet fitting hole of the device body with a hard sphere such as a rope ball having a diameter larger than the wall thickness of the collet fitted in the ball receiving hole, the collet fitting is performed. One side of the sphere is restrained by the inner peripheral surface of the dowel, and the other side of the sphere projecting toward the inner peripheral side of the collet is provided in the handle portion of the tool, and the sphere receiving groove is provided annularly in the circumferential direction. The sphere is fitted in the sphere receiving groove by keeping the sphere fitted in the As long as the tool does not move in the removal direction, it is possible to reliably prevent the tool from being displaced or removed, and when the tool is overloaded, the tool can rotate in the circumferential direction. In this way, it is possible to prevent damage to the tool or the like due to overload.
