Abstract
A clamp device is disclosed which maintains a stable clamped state, even if an object to be fixed, being a work pallet or die, is clamped in a repeated fashion, and which is compact in size and yet capable of clamping the object to be fixed with a large clamping force. In this clamp device (), a plurality of partial sphere-shaped engaging recess sections () are formed in a bush (), and the clamping mechanism () comprises a holding body () having a tubular holding section (), a plurality of steel balls () held movably in the radial direction in the holding section () so as fact to the plurality of engaging recess sections (), and a piston member () inserted movably into an axle hole () in the holding section (), whereby the plurality of steel balls () can be made to engage respectively with the plurality of engaging recess sections () by the clamp operating means () causing the piston member () to move in the axial direction thereof, and the plurality of steel balls () can be made to retreat from the engaging recess sections () by clamp releasing means () causing the piston member () to move in the axial direction thereof.
