A first locking portion restricts displacement of a portion of a first exterior member that is proximate to a second edge portion in a direction away from a body portion. An elastic member supports the first exterior member at a position proximate to the second edge portion. The elastic member retains the first exterior member at a first position where the first edge portion is overlapped with the inner side of the adjacent second exterior member, and is elastically deformed until the first exterior member is displaced from the first position to a second position where the first edge portion is not overlapped with the second exterior member. |
