The skin material 14 is a sheet-like member made of an elastically deformable soft synthetic resin material such as soft polyvinyl chloride, and is superposed on a plate-like base material 16 with a cushion layer 18 interposed therebetween. The substrate 16 is made of a synthetic resin material harder than the skin material 14 such as polypropylene resin. The cushion layer 18 can be made of a foamed material such as a flexible polyurethane foam, but in this embodiment, the cushion layer 18 is made up of a number of minute protrusions integrally formed on the back surface of the skin material 14. The material 14 is overlaid so as to cover the base material 16 with the tips of the microprojections in contact with the base material 16. The outer peripheral portion of the skin material 14 is provided with a folded terminal portion 22 that is folded back in the U shape or V shape and covers the outer peripheral portion 24 of the base material 16 so as to be wound. The folded terminal portion 22 is provided annularly continuously over the entire circumference of the skin material 14 and covers the outer peripheral portion 24 of the base material 16 over the entire circumference. As is apparent from FIG. 4, the folded dimension of the folded terminal portion 22 is the minimum necessary dimension that can cover the outer peripheral portion 24 of the base material 16, and the outer peripheral portion 24 can be overcome only by being slightly elastically deformed toward the outer peripheral side. Can do. The outer peripheral portion 24 of the base material 16 is provided with an annular protrusion 26 protruding toward the skin material 14 along the outer peripheral edge, and the outer peripheral shape of the vehicle interior part 10 is constant regardless of the elastic deformation of the cushion layer 18. It is fixed so that the shape is maintained.

  The folded terminal portion 22 is provided with a large number of insertion portions 30 spaced apart in the circumferential direction on the entire circumference, and the folded terminal portion 22 is locked to the base material 16 through the insertion portion 30 over the entire circumference. To be fixed. The skin material 14 is assembled to the base material 16 without using an adhesive or the like by locking the numerous insertion portions 30 to the base material 16. The insertion portion 30 is provided so as to extend substantially parallel to the back surface of the base material 16 continuously from the tip of the folded terminal portion 22, while the back surface of the outer peripheral portion 24 of the base material 16 A plurality of locking projections 32 are provided corresponding to the insertion portion 30.

  Since the insertion portion 30 is intermittently provided in the circumferential direction of the folded terminal portion 22, as shown in FIGS. 5A to 5B, due to elastic deformation of the folded terminal portion 22 and the like. The outer peripheral portion 24 of the base member 16 can be overcome with relative ease and go around to the back side. A flat inclined surface 36 is provided at the distal end of the insertion portion 30, and an uneven surface 37 that is inclined as a whole is provided at the outer end edge of the outer peripheral portion 24 of the base material 16. When the insertion member 30 is pressed against the outer peripheral portion 24 of the base material 16 as shown by an arrow A when the skin material 14 is superimposed on the base material 16 and assembled as shown in FIG. As a result, the insertion part 30 is slid to the outer peripheral side of the base member 16 as shown by an arrow a and gets over the outer peripheral part 24. The inclined surface 36 and the concavo-convex surface 37 function as a first guide portion, and the insertion direction 30 is caused to slide and move to the outer peripheral side of the base material 16 by the pressing force in the assembling direction indicated by the arrow A. As appropriate, it is determined in consideration of the assembly direction A and the like. The folded terminal portion 22 between the numerous insertion portions 30 that are intermittently spaced apart from each other in the circumferential direction is pulled by the insertion portion 30 when the insertion portion 30 gets over the outer peripheral portion 24, and the outer peripheral portion 24. The outer peripheral portion 24 is covered so as to be wound around.

  As shown in FIG. 5 (b), the insertion portion 30 that has passed over the outer peripheral portion 24 of the base material 16 is returned and deformed so as to be inserted into the insertion recess 34 by the elastic restoring force of the folded terminal portion 22.
