PROBLEM TO BE SOLVED: To connect a pallet to a lead-in nipple with no clearance by exerting tensile force practically vertical on a surface of the pallet to the lead-in nipple. SOLUTION: A spherical body makes contact with a recessed part 16 corresponding to a head of a lead-in nipple 14 as a ball gauge and forms an abutting connecting state between the lead-in nipple 14 and a clamping element of a clamping cylinder. Consequently, the lead-in nipple 14 is led in the clamping cylinder, and the clamping cylinder is simultaneously supported on a clamping surface 29. Accordingly, as stabilization of the lead-in nipple 14 to a pocket hole 2 with no clearance is done while tensile force is exerted to the lead-in nipple 14, a pallet 1 is drawn to the clamping cylinder with no clearance. |
