An inner case 5 is composed of an inner panel 5a connected to an inside of the outer panel 4, and a side wall 5b that forms a space for housing the retainer 3. The inner panel 5a is composed of a supporting portion 51 connected to the fixing portion 4c of the outer panel 4, a flap portion 52 welded to the door portion 4d, and a hinge portion 53 formed between the supporting portion 51 and the flap portion 52. The hinge portion 53 includes a top portion 53a, a supporting portion side connecting portion 53b for connecting the supporting portion 51 and the top portion 53a, and a flap side connecting portion 53c for connecting the flap portion 52 and the top portion 53a. A thin-walled portion 54 formed to have a smaller wall thickness than the other portion of the hinge portion 53 is provided in the supporting portion side connecting portion 53b (Fig. 1). |
