SOLUTION: A plurality of supports 1 are erected to surround the outer periphery of the parking space. An outer beam 2 is provided between the adjacent supports 1 to surround the outer periphery of the parking space. A beam 3 is provided over a section between the supports 1 inside the parking space which is surrounded by the outer beam 2.
