INTERIOR PART AND WORKING TOOL FOR MANUFACTURING INTERIOR PART

PROBLEM TO BE SOLVED: To fix a skin material without using an adhesive to obtain an interior part with superior finishing touch and improve the workability of skin material attachment.SOLUTION: An interior part includes a core material and a skin material covering the core material. The skin material has a skin body covering the exterior of the core material and a skirt edge which is caught in the inner surface of the core material to support the skin material on the core material. The skirt edge has a plurality of locking holes arranged along the outer edge of the skin material, a skirt edge base end located closer to the skin body than the locking holes, a skirt edge front end extending closer to the outer edge of the skin material than the locking holes, and a plurality of bridging portions which are formed between locking holes adjacent to each other and connect the skirt edge base end to the skirt edge front end. The core material has a locking wall which extends along the periphery of the core material on the inner surface side of the core material and to which the skirt edge of the skin material can be fixed. The locking wall has a plurality of incision slots capable of catching therein the bridging portions of the skin material and a plurality of engaging walls which are formed between incision slots adjacent to each other and penetrate the locking holes when the bridging portions are caught in the incision slots, the incision slots and engaging walls being formed on the top of the locking wall.
