For example, in the above embodiment, the first support 23 of the first molding die 21 is fixed to the first fixing plate 21B, and only the second support 33 of the second molding die 31 is opened and closed from the second fixing plate 31B. By moving in the direction, the first molding die 21 and the second molding die 31 may be molded. Even in this case, since the urging force on both the sliders 28 and 38 is set to be smaller than the force for clamping the first molding die 21 and the second molding die 31, the slider 28 is set to the first molding die 21 (specifically, the first molding die 21 (specifically,). , The slider 38 moves relatively toward the first fixing plate 21B with respect to the fixed base 25), and the slider 38 is second-fixed relative to the second forming mold 31 (specifically, the second main mold 32). Move toward the plate 31B. Then, the portion of the skin material 15 sandwiched between the first inclined clamp 41 and the second inclined clamp 42 can be loosened. Further, in this case, the molding becomes stable when the fixing clamp 51 sandwiching the skin material 15 moves so as to approach the molding mold on the fixed side.

(6) In the above embodiment, the portion of the skin material 15 to be attached to the convex portion 13 of the front side surface 11A of the base material 11 is loosened in advance, but the front side surface 11A of the base material 11 has a recess. The portion of the skin material 15 to be attached to the recess may be loosened in advance.
