Therefore, not only the displacement of the peripheral edge 15 a of the upholstery material 15 that tends to narrow inward but also the displacement thereof that tends to widen outward can be appropriately restricted. For this reason, curling of the upholstery material 15 in various directions can be more reliably suppressed.
  • the second side wall 25 and the second protruding wall 27 are provided in the linear parts 13 b on both the left and right sides of the base plate 13 and the linear part 13 b on the front side in the thick cushion material 14 superimposed on an upper surface.

Therefore, when the upholstery material 15 is attached, the tightening cord 18 or the peripheral edge 15 a of the upholstery material 15 can be easily arranged inside the first protruding wall 26 or the second protruding wall 27 , continuously pushing the tightening cord 18 or the peripheral edge 15 a of the upholstery material 15 into the recessed groove 19 on the base plate 13 . For this reason, the upholstery material 15 can be easily attached. Moreover, since the displacement of the tightening cord 18 or the peripheral edge 15 a of the upholstery material 15 is restricted within the continuous recessed groove 19 , the curling of the upholstery material 15 can be made less likely to occur.

  • the first protruding wall 26 and the second protruding wall 27 provided in the linear parts 13 b are arranged so as to be separated from each other in the direction in which the tightening cord 18 extends, and to be adjacent to each other. Therefore, the length of the first protruding wall 26 and the second protruding wall 27 can be sufficiently extended without causing any contact between tip parts of the first protruding wall 26 and the second protruding wall 27 . For this reason, the first protruding wall 26 and the second protruding wall 27 can be easily bent and deformed when the tightening cord 18 or the peripheral edge of the upholstery material 15 is attached. Therefore, this can facilitate the attachment of the upholstery material 15 .
