Abstract
A work pallet (3) has an under surface opened to provide a positioning hole (12). The positioning hole (12) has an upper wall which supports a pull rod (13) diametrically movably. A clamp pallet (2) projects an annular plug portion (21), onto which a shuttle member (23) is externally fitted. The shuttle member (23) makes a tapering engagement with the positioning hole (12). The plug portion (21) has a cylindrical hole (21a), into which a transmission sleeve (31) is inserted. The transmission sleeve (31) supports an engaging ball (34), which engages with an engaged portion (13b) of the pull rod (13). Defined between the cylindrical hole (21a) and an outer peripheral surface (31b) of the transmission sleeve (31) is a flow passage (43) through which cleaning compressed air passes.
