Pallet storage device

Abstract

The present invention provides a pallet storage device in which a pallet support base can stably support a pallet on which a workpiece can be attached. [Solution] The pallet storage device for accommodating a pallet 70 on which a workpiece is attached includes a pallet support base 42. The pallet support base 42 has pins 46, 47 and a contact member 50 on its upper surface 42A. The contact member 50 has contact surfaces 52A, 53A. The contact surfaces 52A, 53A are flat surfaces. When the pallet 70 is placed in the pallet placement section 45, the pins 46, 47 are inserted into holes in the bottom surface of the pallet 70. The contact surfaces 52A, 53A contact the bottom surface of the pallet 70 at positions different from the positions of the holes.
