SOLUTION: Mutual mating surfaces 533 of slide blocks 531 constituting a movable core 53 are slanted. In other words, a normal line to the opposite mating surfaces 533 is non-parallel to a movable plane of the core, and an inside line 530 on the male die 51 side of a contour showing the shape of projection of the group of the slide blocks 531 to the movable plane of the core is already brought to a continuous state just before these slide blocks 531 are gathered completely. Although the slide blocks 531 are gathered, sliding on the surface of a skin material 61, on the occasion when the skin material 61 is pressed on a male die 51, a wrinkle hardly grows in a gap 534, since the direction wherein the wrinkle is apt to run does not coincide with the direction of running of the gap 534.
