Reference numeral 1 is a "side member" constituting the door 2.
A door inner panel is shown, and a trim 3 is detachably attached to the door inner panel 1. Reference numeral 4 is a grip fixed to the trim 3.

The trim 3 is made of a synthetic resin plate and has an armrest portion 6 formed thereon, a core plate 5, a first decorative member 7 made of a cloth material or the like for covering the surface of the core plate 5, and the first decorative member. The second decorative member 11 includes a second decorative member 11 that partially covers the first decorative member 7 with an end portion 10 being grained in the grooves 9 and 9 of 7, and a leg portion 13 formed on the core plate 5. A peripheral end portion 15 of the trim 3 is in contact with the door inner panel 1. At the peripheral end portion 15 of the trim 3, the first decorative member 7 is folded back on the core plate 5 to be surely covered.

The leg portion 13 includes a first leg 21 and a second leg 2.
5 and third legs 29, 29.

The first leg 21 is provided with a clip 19 as a "support member" which is arranged along the panel surface of the door inner panel 1 and is detachably fixed to the through hole 17 of the door inner panel 1. A notch 20 for supporting is formed.

The second leg 25 is projected from both ends 23, 23 of the first leg 21 in a slanted shape extending in an angle Θ of 30 to 60 ° with respect to the panel surface of the door inner panel 1. It becomes.

The third leg 29 has a substantially right-angled shape with respect to the panel surface of the door inner panel 1, and the first leg 29 is formed in the middle thereof.
The thin portions 27, 27 are formed on the inner surface 14.

Second thin portions 31, 31 are formed on the inner surface 14 of the joint portion of the first leg 21 and the second leg 25.

Third thin portions 33, 33 are formed on the outer surface of the joint between the second leg 25 and the third leg 29.

The first, second and third thin portions 27, 31,
Reference numeral 33 denotes a fuse shape capable of withstanding a fastening load of the trim 3 onto the door inner panel 1, that is, one end 21a, 25a, 2 of the first, second, and third legs 21, 25, 29.
The groove 35 is opened on the 9a side, but the other end 21
