Normally, side garnishes are assembled to the center garnish at multiple locations (for example, two locations, one at the front and one at the rear). When considering assembly workability, it is desirable that the assembly direction at each assembly location be the same. However, due to constraints such as the arrangement and design of the parts constituting the cowl portion, the direction of assembly at each assembly location may differ. In this case, the side garnish is attached to the center garnish while being slightly rotated. For example, the side garnish is pressed from above the vehicle, rotated, and assembled to the center garnish.

In this case, with the structure as in the above example, the assembly work using the clip portion becomes complicated, such as pressing and rotating the side garnish from above the vehicle. On the other hand, in order to facilitate the assembly work, there is an increased requirement for shape accuracy (dimensional accuracy) of the clip portion, etc., which may increase the manufacturing cost of the parts. Therefore, in a structure like the above example, when there are multiple assembly points and the assembly directions are different, it is difficult to improve the assembly workability and avoid excessive shapes of each part. There was room for improvement in eliminating the need for precision.
