Abstract:
A clamp apparatus including two pairs of first and second clamp arms, which are supported rotatably with respect to a body and are disposed mutually in parallel. First and second cam members including respective cam surfaces are provided on ends of the first and second clamp arms. The first cam members are pressed by rollers upon lowering of a block body under a driving action of a first cylinder that makes up a drive unit. The first clamp arms are rotated to assume a clamped state. The second cam members are pressed by rollers upon lowering of a block body under a driving action of a second cylinder of the drive unit, whereby the second clamp arms are rotated to assume a clamped state.
