  Then, as shown by reference numeral 4 ′ in FIG. 7, when the assembly of the opening trim 4 reaches the parting part (12, 22) with the front pillar trim 2, as shown in FIG. As the opening trim 4 is pushed, the guide piece 24 intervenes between the fitting portion 43 and the lip portion 42, and the lip portion 42 is inserted into the fitting portion 43 as shown in FIGS. 5B and 6. Therefore, the lip portion 42 is guided to the front surface side of the rear end portion 21 of the front pillar trim.

In particular, as shown in FIG. 5 (a), the opening trim 4 is fitted by a configuration in which the tip of the guide piece 24 protrudes from the tip 13a of the instrument panel extension 13 by an appropriate dimension difference e. Even when the joint portion 43 and the lip portion 42 are in close contact with each other by passing through the relatively narrow gap g1, the guide piece portion 24 can reliably intervene between the fitting portion 43 and the lip portion 42.

  Furthermore, as shown in FIG. 4, the protruding shape of the guide piece 24 toward the door opening flange 30 side is separated from the fitting portion 43 by a configuration that continues upward beyond the parting portion (12, 22). The lip portion 42 is surely and smoothly guided to the surface side of the rear end portion 21 of the front pillar trim, which is advantageous in maintaining good appearance of this portion.

  In the above-described embodiment, the case where the opening trim 4 is assembled from the lower end 44 on the front side of the vehicle has been described. However, the lip portion 42 is installed by the guide piece portion 24 when the front trim trim is assembled from the rear edge portion 21 side. It can be said that it is advantageous for maintaining the appearance of this portion satisfactorily by being guided to the rear surface side of the ment panel extending portion 13 without difficulty.

  As mentioned above, although one Embodiment of this invention was described, this invention is not limited to the said embodiment, Various deformation | transformation and a change are possible based on the technical idea of this invention.

  For example, in the said embodiment, although the case where the inward side wall part 10 was provided in the side part of the instrument panel 1 was described, the alignment part (side edge part 12) with the front pillar trim lower end part 12 in the instrument panel main-body part 15 is described. This is also possible when the extending portion 13 is provided on the outer surface of the instrument panel main body portion 15.
