Abstract
Each of master jaws (17) has a middle spherical part guided for sliding movement by a spherical guide surface (16) formed in a chuck body (2), a round back end part (19) extended slidably through a spherical bearing member (12) supported on a support member (10) attached to a middle part of a driving member (5). Each master jaw (17) is provided with a through hole (26) extending between the front and the back end thereof and a sliding member (30) is inserted in the through hole of the master jaw (17) through the front end of the same so as to come into sliding contact with a stopper (36) attached to a chuck body (2). Therefore, the state of sliding contact between the sliding member (30) and the stopper (36) can be adjusted on the side of the front part of the chuck and work for adjusting the state of sliding contact can be easily achieved.
