Abstract: A support structure for a fuel lid attached by a hinge to a vehicle body is provided with an annular rubber seal, which is provided on the vehicle body to surround an oil filler port in the vehicle body. The rubber seal has a top surface and an inner circumferential surface. The support structure includes a contact plate provided on a back surface of the fuel lid. The contact plate contacts the rubber seal when the fuel lid is in the closed state. The contact plate has an upper surface contact portion for contacting the upper surface of the rubber seal, and an inner-surface contact portion for contacting the inner circumferential surface of the rubber seal.

Abstract: In a joining structure of a lid box according to an embodiment of the invention, a joining area where a joining surface of a joining portion of a side outer panel faces a joining surface of a joining portion of the lid box includes a first area where the joining surfaces come into contact with each other and are supposed to be subjected to spot-welding and a second area where the joining surfaces are separated from each other by a predetermined gap and are supposed to be subjected to laser-welding, and the spot-welding is performed on the first area or the laser-welding is performed on the second area. For that reason, since the joining states respectively suitable for the spot-welding and the laser-welding are realized, sufficient welding quality is ensured in both the spot-welding and the laser-welding.

Abstract: A reinforcing structure of a vehicle door enables a part to be housed in the vehicle door and prevents a luggage compartment space from being decreased and an inner panel from being damaged by the weight of the part. A back door 10 includes an inner panel 16 and an outer panel 18, and the inner panel 16 and the outer panel 18 are joined to each other to form an internal space 20 therebetween. The inner panel 16 has a part housing recess 24 that is formed from the outer surface side (from a luggage compartment 23) toward the internal space 20. A reinforcing member configured to join the part housing recess 24 to the outer panel 18 is provided.
