Then, when injecting and foaming urethane foam,
As shown in the figure, a part of the urethane flows into the screw hole 6 formed in the core member 7, and the screw hole 6 is blocked by the urethane foam 9 ', so that the screw hole 6 There is a problem that it will not be used. Therefore, in order to eliminate this problem, as shown in FIG. 4, a seal tape 10 for preventing urethane from flowing into the screw hole 6 is attached to the back surface of the instrument core member, and then, the seal tape 10 is placed in the molding die. An improvement plan to set the tape is proposed, but in this case, the step of attaching the seal tape 10 is increased, which causes a problem that the product cost is increased.
Further, in this case, if the depth 1 of the screw hole 6 to be formed in the instrument core 7 is set to be long, the screw hole 6 can be a bottomed hole instead of a through hole.
Although it is possible to prevent urethane from flowing into the interior,
In this case, a sufficient depth 1 has to be formed so that the depth 1 of the screw hole 6 can correspond to the length of the mounting screw 5, which causes a problem that the core material 7 becomes large. Note that
Reference numeral 11 denotes a defroster duct that is fixed to the vehicle body 4 in advance.

形成されているものである。That is, in this embodiment, when the instrument core material 7 is molded, the screwing holes 6 of the mounting screws to be formed in the core material 7 are made into bottomed holes, and the urethane foam layer 9 is foam-molded. The purpose is to prevent the urethane resin from flowing into the screw holes 6 at times. Further, the thickness of the bottom wall 12 forming the bottomed hole is easily destroyed by the screwing force of the mounting screw 5 when the mounting screw 5 is screwed into the screwing hole 6, and the tip of the mounting screw 5 is elastic. It is formed on a burr-shaped bottom wall 12 of, for example, about 0.5 mm so that it can be projected into the pad layer 9.

易となる。As described above, in this embodiment, the mounting screw threaded screwing hole 6 formed in the core member 7 is a bottomed hole for preventing the urethane resin from flowing into the screwing hole 6. Therefore, the urethane resin for foam-molding the urethane foam layer 9 does not flow into the screw hole 6 between the core material 7 and the skin material 8, so that the screw hole 6 is made of urethane foam. The problem of being blocked by does not occur. Further, the thickness of the bottom wall 12 of the screwing hole is easily broken by the screwing force of the mounting screw 5 and the tip of the mounting screw 5 can be thrust into the urethane foam layer 9, so that the mounting screw 5 used. It is easy to manage the length.
