PROBLEM TO BE SOLVED: To obtain a connection force to resist a pull force to be added to the cover cloth in usage, and also to easily remove the cover cloth in a division and collection work. SOLUTION: The peripheral edge part of a synthetic resin-made seat board 1, whose upper surface is covered with the cover cloth 4 via a buffer board, includes a ring shape groove 11 on the lower surface. A plurality of through-holes 12 are arranged in the groove 11 in a peripheral direction, and filled with a hot-melt adhesive. The peripheral edge part of the buffer board is adhered onto the upper surface of the seat board 1 with hot-melt adhesive, and the peripheral edge part of the cover cloth 4 is adhered onto the lower surface 1a of the seat board 1 with the hot-melt adhesive, so that the connection force to to resist the pull force to be added to the cover cloth 4 in usage is obtained. Besides, the cover cloth 4 is pulled in the thickness direction of the seat board by picking up the peripheral edge part of the cover cloth 4, so as to be separated. COPYRIGHT: (C)2004,JPO
