摘要： A chuck having the function of pulling in work is constructed so that the function possessed by an axially movable chuck body portion is superceded by an immovable body portion, a plunger and an urging means, thereby dispensing with the movable chuck body portion. That is, it is a chuck of a construction in which, of the functions of the conventional movable body portion, the guide function of controlling the movement of the jaw axially and circumferentially of the chuck shaft is superseded by a fixed body portion (10) and an urging means (50) for pressing the jaw (20) forwardly of the chuck, while the radial movement of the jaw for gripping the work is effected by a wedge means (40), and the rotational moment of the jaw produced as a reaction to the work holding force is supported by the wedge means (40) cooperating with part of a plunger (30) or the plunger and the cylinder section (16) of the front of the chuck body main body.
