Abstract
An annular piston (20) is inserted into a lower portion of a guide bore (17) of a housing (11), and a transmission sleeve (24) is inserted into the cylindrical bore (20a) of the piston (20) with a first annular gap (21) defined therebetween. A ring-shaped operation member (36) is inserted into an upper portion of the guide bore (17) with a second annular gap (22) defined therebetween. At the time of clamping, first a pull bolt (3) is inserted into the sleeve (24) and then the sleeve (24) is driven downward by the piston (20). Thereupon, balls (37) are changed over to an engagement position (X) by the operation member (36), so that a driving force of the piston (20) can be transmitted to a workpiece (1) through the sleeve (24), the balls (37) and the pull bolt (3).
