  • Publication number: 20180272413
    Abstract: According to one embodiment, a clip is assembled to an inner member in a state where the clip penetrates through a through-hole of the inner member. The through-hole penetrates between a bottom surface of a recessed part and an inner surface in the inner member, in other words, between front and rear surfaces of the inner member. This configuration enables a part where the inner member holds the clip to be formed relatively thicker. Thus, strength of a connection part of the clip and the inner member can be further enhanced.
