(1) As shown in FIG. 19, the flange portion 33 of the cup holder 30 may not have the flange groove 34 and the bezel 40 may have neither the frame-like protrusion 61 nor the frame groove 62 . Also with this configuration, the edge of the skin opening 15A can be sandwiched between the flange 33 of the cup holder 30 and the opening edge of the bezel 40, and leakage of the foam material 71 can be suppressed.

(2) A configuration in which a through hole is formed in the outer flat portion 44 of the bezel 40 and the pad 12 is arranged between the outer flat portion 44 and the skin 15 may be employed.

(3) In the above embodiment, as shown in FIG. 8, the front engaging leg portion 53 and the rear engaging leg portion 54 are arranged in the facing direction of the front side portion 24F and the rear side portion 24B of the front connecting member 24 of the support frame 20. That is, although the rib structure has the engaging ribs 53A and 53B extending in the direction parallel to the front-rear direction, the front engaging leg portion 53 and the rear engaging leg portion 54 have the same structure as the flexible piece 58. An elastic piece structure may also be used. If the front engaging leg portion 53 and the rear engaging leg portion 54 have an elastic piece structure, they can be easily elastically deformed. , a high locking force can be obtained.

(4) In the above embodiment, the cup holder 30 and the bezel 40 are asymmetrical in the front-rear direction, but the cup holder 30 and the bezel 40 may be symmetrical in the front-rear direction.

(5) By lining the skin 15 with a foam sheet or the like to provide elasticity in the thickness direction, as shown in FIG. The upper surface of the lower flat portion 35</b>C of the protrusion 35 and the upper surface of the lower flat portion 35</b>C of the cup holder 30 may be inclined upward as they are separated from the cup receiving portion 31 . According to this configuration, even when the cup holder 30 receives an external force from the bottom wall side, the flexible piece 58 moves in a direction in which the fitting of the side engaging projection 35 with the fitting recess 36 becomes deeper. It is possible to prevent the cup holder 30 from coming off the bezel 40 .
