The first and second support frames are arranged on the facing ends of two decks. The first and second finger plates are arranged on the tops of the first and second support frames and comprise multiple first and second fingers(310,410) and first and second spaces(320,420). The first and second fingers are protruded toward the first and second support frames. The first and second spaces are opened toward the first and second support frames. The filling member is formed in a block shape using a flexible material. |
