An anchor recess 13 (a through hole in the illustrated example) is opened in the fitting surface (the front surface b and the left and right side surfaces c in the illustrated example). Further, at the lower end of the striker 10, a backing plate 14 that extends downward continuously from the rear surface d is continuously provided.

The striker 10 is attached to the console 1 at the same time as the console 1 is manufactured. That is, the console 1 is manufactured by bringing the surface layer portion 3 into close contact with the inner surface of the molding die and then injecting a foamable urethane stock solution into the molding die to foam the stock solution.
It is fitted and installed on the inner surface of 11. At that time, the front surface b and the left and right side surfaces c of each anchor recess 13 are faced so as to closely contact the front inner surface and the left and right side inner surfaces of the mounting recess 11.

At the same time as the undiluted solution foams to form the core 2,
As shown in the figure, a part of the core portion 2 and a part of the surface layer portion 3 covering the core portion 2 are bulged into the respective anchor recess portions 13 by the foaming pressure of the core portion 2, and accordingly, the respective anchor recess portions are formed. Anchor protrusions 15 that fit into the protrusions 13 are integrally formed on the inner surface of the front portion of the mounting recess 11 and the inner surfaces of the left and right side portions, respectively.

Thus, the fitting of the anchor projection 15 and the anchor recess 13 of the striker 10 which are bulged by utilizing the foaming pressure of the core 2 without specially forming a cut or a through hole in the surface layer 3. As a result, the striker 10 is prevented from coming off the mounting recess 11, so that the striker 10 can be firmly and immovably held in the mounting recess 11. Further, when the striker 10 is attached, it is possible to omit a work process of making a cut in the surface layer portion 3 or sealing the cut, so that it is possible to reduce the man-hours of the mounting work and simplify the process as a whole. Moreover, the surface of the surface layer portion 3 adjacent to the striker 10 can be a continuous surface without breaks, which is effective in preventing the occurrence of cracks in the surface layer portion 3. Further, since it is not necessary to embed a part of the striker 10 in the core portion 2, it is not necessary to specially form a thick portion for embedding the striker in the core portion 2 itself, unlike the conventional structure. The moldability of the core portion 2 is good and the molding cost can be reduced.

As shown in FIGS. 6 to 8, the armrest 8 includes a rectangular thin synthetic resin inner box body 18 having a downward opening 17 facing the opening 16 of the storage case 6 and an inner box body 18 thereof.

A long groove-shaped engaging recess 30 is formed between the outer surface and the outer surface.

In the core portion 20 of the outer box body 19, a pair of engaging convex portions 33 is formed on the inner side surfaces of both long side sidewalls 32 via the ribs 31, and each engaging convex portion 33 and the long side sidewall 32. They extend substantially parallel to the vicinity of the opening 34 of the outer box body 19. In each long side wall 32, both engaging projections 33 are arranged so as to sandwich the longitudinal side bisector of the long side wall 32.

The engagement protrusions 33 of the outer box body 19 are engaged with the engagement recesses 30 of the inner box body 18. As a result, inward bending of both long-side sidewalls 29 of the inner box body 18 is prevented, so that no gap is created between both openings 17, 34 of the inner box body 18 and the outer box body 19. .

Further, on both long-side sidewalls 29 of the inner box body 18, locking claws 35 are respectively provided on the long-side sidewalls 29 at bisectors in the longitudinal direction. Each locking claw 35 has a mountain-shaped locking portion 36 with its apex facing outward on the tip end side, and has a holding claw 37 on the base end side. The holding claw 37 bites on the inner surface of the holding hole 38 on the outer surface of the long side wall 29.
