PURPOSE:To hold a pallet precisely on a jig body by furnishing a clamping means, which locates and holds the pallet with a work fitted on the rotatable jig body mating with a processing device, constituting a ring-shaped transport path, and arranging a guide rail supporting the pallet with possibility of advancing and retracting to/from the jig body. CONSTITUTION:A jig body 360 is rotatable under acting of an actuator, and guide rails 368, 370 constituting a ring-shaped transport path are supported on this jig body 360, and guide rods 362a, 362b, 364a, 364b are arranged with possibility of advancing and retracting. Further this jig body 360 is furnished with a clamping means to locate and hold a pallet 50 on which a work W is fitted. When pawls 376c, 376d of this clamping means hold the pallet 50 on the jig body 360, the guide rails 368, 370 supporting the pallet 50 are displaced toward the jig body 360 with the aid of the guide rods 362a, 362b, 364a, 364b. This facilitates indexing operation for the pallet 50. |
