In addition, the reinforcing member 7 is arranged in the skin 2, the tip of the protrusion 11 introduced into the opening 21 is introduced into a through hole 71, so that the reinforcing member 7 is firmly fitted to the protrusion 11, and a foaming material is poured into a space surrounded by the skin 2 and the inner plate 1 so that the skin 2 and the inner plate 1 are integrally formed into a foam.
