的としている。 This invention solves the above problem by fixing a flange member made of the same material as the outer panel with rivets or the like around an inner panel made of metal or resin that is different from the outer panel made of metal. By sandwiching the periphery of the flange member with a hemming portion formed at the edge of the outer panel, and joining the hemming portion and the flange member by welding, the outer panel and the inner panel are made of different materials to reduce weight. In addition, it is an object of the present invention to provide an automobile panel joining structure that can reliably join them by welding.

つてアウタパネル１に固着されている。 A hemming portion 3 bent inward is formed at the edge of the outer panel 1. On the other hand, on the outer periphery of the inner panel 2, a bent part 4 which is bent at a substantially right angle is formed over the entire circumference. The above bent part 4
One end portion 6 of an aluminum flange member 5 having an L-shaped cross section is overlapped over the entire circumference of the bent portion 4, and a plurality of bent portions 4 and one end portions 6 of the flange member 5 are formed on the outer surface of the flange member 5. It is fixed with rivets 7 (only one is shown). The above flange member 5
The other end portion 8 is clamped around the entire circumference by the hemming portion 3 of the outer panel 1, and is further fixed to the outer panel 1 by spot welding to the hemming portion 3 at appropriate intervals.

できる。 In the panel joint structure having the above configuration, the outer panel 1
Since the inner panel 2 is made of aluminum, weight reduction can be achieved, and since the inner panel 2 is made of a steel plate, the required rigidity can be obtained. Further, an aluminum flange member 5 is fixed around the steel plate inner panel 2 with rivets 7, and the periphery of the aluminum flange member 5 is clamped by a hemming portion 3 formed on the edge of the aluminum outer panel 1. , hemming portion 3 of the aluminum outer panel 1
and the flange member 5 are joined by spot welding. Therefore, the aluminum outer panel 1 and the steel plate inner panel 2, which are made of different materials, can be joined by spot welding, which is the same method as before and is reliable and has good workability. and can be joined. In addition, one end of the flange portion 5 having an L-shaped cross section and the inner panel 2
The bent portions 4 of the bolts are overlapped and fixed with rivets 7, and this overlapped portion also serves as a continuous reinforcing rib, so that the strength against bending and torsion of the bolts can be improved. can.
