As a result of such a configuration, claim 8 is also provided.
The position regulation protrusion described in (1) does not become a separate part, the number of parts does not increase, and the number of mounting steps can be reduced. In the present invention, the position regulating protrusion is constituted by a plurality formed in such a manner as to be intermittently formed in a longitudinal direction of the concave groove.

As a result of such a configuration, the position regulating protrusion has a structure in which the convex flange portion is intermittently pressed, so that the operation of inserting the convex flange portion into the concave groove can be facilitated, and After the insertion, the convex flange is pressed against the inner wall surface of the concave groove by the multiple positioning protrusions, so that the multiple positioning protrusions affect each other to compensate for manufacturing errors and thermal deformation of the upper trim or lower trim. As a result, it is possible to maintain an aesthetic appearance without causing a gap between the outer inner wall surface of the concave groove and the convex flange portion.

Further, in the present invention according to claim 9,
The position restricting projection has an elastically deformable projection structure, and is configured so that the convex flange portion is elastically pressed against an outer one of the inner wall surfaces facing each other in the concave groove.

[0023] As a result of this configuration, since the position regulating protrusion is elastically deformed, the work of inserting the convex flange portion into the concave groove becomes easy, and after the insertion, the position regulating protrusion makes the convex flange portion concave. Since the ribs are elastically pressed against the outer inner wall surface of the groove, the manufacturing error and thermal deformation of the upper trim or lower trim are absorbed by the elastic force of the rib, and the gap between the outer inner wall surface of the groove and the convex flange is always maintained. The aesthetic appearance can be maintained without causing any gaps.
