Abstract

PURPOSE: To simplify the operation by obtaining high fastening accuracy and large tightening follow-up effect by providing the drill chuck constructed so that the force of a spring energizes a locking ring in the rotating direction of a chuck sleeve corresponding to opening of the drill chuck. CONSTITUTION: The force of a spring energizes a locking ring 11 in the rotating direction of a chuck sleeve 4 corresponding to opening of a drill chuck. To generate the spring force, there is provided only one coil spring 15 working in the axial direction and in the circumferential direction, and the coil spring 15 is disposed in a ring-like cutout 16 between the chuck body 1 and the locking ring 11. The end part 15' of the coil spring 15 is bent in the axial direction and in the radial direction in the axial direction and in the circumferential direction to be fitted in the holes of the chuck body 1 and the locking ring 11 in such a manner as to be substantially connected in form. By this arrangement, high fastening accuracy and large tightening follow-up effect are provided and the number of parts can be decreased to simplify the operation.
