When machining of a workpiece mounted on a first pallet by a machine tool is ended, power of a driving motor is transmitted through a cylindrical cam and a cam follower to a clamp member to unclamp a first pallet clamped on a table of the machine tool by the clamp member. Then, the power is transmitted to a swing arm to unload the first pallet from the table to a stand-by position and a second pallet, mounting thereon a workpiece to be machined, is loaded from the stand-by position to the table by the swing arm. The second pallet is the clamped on the table by the clamp member and the pallet exchange operation is complete.
