４の状態に接着固定される。Subsequently, immediately after the vacuum forming, the skin 4 is positioned near the outer peripheral position of the ornamental portion 7 (the non-coated portion 3 of the adhesive).
Disconnect with As shown in FIG. 6, in this example, the outer skin 4 was cut in an annular shape along substantially the vicinity of the inside of the groove 1A. A cutter 9 having a cutting blade 9A of a predetermined shape was used for cutting the skin 4 of this example. That is, the skin 4 covered with the groove 1A as shown in FIG. 8 is brought into close contact with the surface of the base material 1 and the inside of the groove 1A in the vacuum forming as shown in FIG. Since the skin 4 is cut immediately after the vacuum forming, as shown in FIG. 10, both ends 4B of the cut skin 4 in the groove 1A are cut.
Until the stress of the skin 4 due to molding is eliminated, the surface is returned to the bonded portion side of the skin 4, the stress is released, and the skin 4 is bonded and fixed to the state of the skin 4 shown in FIG.
