Abstract

PURPOSE: To prevent flying-outs of broken parts of a lead screw by fixing a stopper to a chuck body and abutting an engaging part formed in the stopper to an engaging part formed in the lead screw.
CONSTITUTION: The chuck body 14 rotates together with a work and thus the working operation is started. If there occurs a breakdown in the lead screw 18 at a point 32, the outer part 33 of the broken lead screw 18 is apt to fly out of the outer opening of a groove 15 by the centrifugal force. According to this invention, however, the outer broken part 33 is prevented from flying out of the groove 15 by the stopper 28 projecting inside of the groove 15 because the outermost thread 31 on the screw surface of the lead screw 18 engages with the stopper 28.
