Claims

[Scope of Claim for Utility Model Registration] A housing and a clamp member that is movable back and forth between a retraction limit position where the housing retracts into a housing chamber and a forward limit position where the action point of the front end protrudes outside the front end of the housing chamber. In a wedge-type clamping device that includes a wedge-shaped member inserted into a wedge-shaped gap between the upper wall of the storage chamber and the clamp member, and a hydraulic cylinder that drives the wedge-shaped member back and forth, a horizontal In addition to forming a guide surface, a guided surface that is always in contact with the guide surface is formed on the rear lower surface of the wedge member, and an engagement recess that expands downward is formed in a portion of the guided surface that is a predetermined distance away from the rear end. The clamp member is provided with an engaging member that is movable up and down and has an engaging portion that releasably engages with the engaging recess when the clamp member is at its retractable limit position and the wedge member is at its retractable limit position. A wedge-type clamp device characterized in that an engaging member is elastically biased upward by a spring.
