Abstract
A clamp apparatus is equipped with first and second clamp arms supported rotatably with respect to a body, and a drive unit having a pair of first and second pistons displaced under the supply of a pressure fluid. A driving force of the drive unit is transmitted to the first and second clamp arms through knuckle joints, which are connected to first and second piston rods, power-boost levers, and link arms. The power-boost levers are formed such that the length from a support pin toward the knuckle joint is longer than the length from the support pin toward the link arm.
