Abstract
A fulcrum portion (5a) provided in a midway portion of a clamp arm (5) in the left and right direction is supported vertically pivotably by a housing (3) through a pin (13). A first shaft (21) of a transmission member (18) is fitted into a driven portion (5b) provided in the right portion of the arm (5). A second shaft (22) of the transmission member (18) is so supported by support grooves (25) of the housing (3) through rollers (24) as to be movable in the front and rear direction. The first shaft (21) and a piston rod (50) of a pneumatic cylinder (6) are connected to each other by a lever (19). At the time of clamping, the first shaft (21) is eccentrically rotated clockwise about an axis (A) of the second shaft (22).
