MOUNTING STRUCTURE OF EXTERIOR PART

In a mounting structure of an exterior part, a molding has a recess capable of being fitted to an outer periphery of the exterior part, as seen in a cross-sectional view. The outer periphery includes a recessed corner portion at which two sides of the outer periphery cross each other. One of the two sides constituting the recessed corner portion includes a protrusion capable of being fitted into the recess of the molding. The other of the two sides includes a cutout portion disposed adjacent to the protrusion, the cutout portion permitting insertion of the molding therethrough under a condition where the exterior part is mounted on a front surface of a main member. The exterior part is mounted on the front surface of the main member under a condition where an end portion of the molding mounted on the one side is inserted into the cutout portion.
