PROBLEM TO BE SOLVED: To obtain a vehicle battery mounting structure capable of suppressing the generation of rust due to electrical corrosion even if an opening portion for drainage is formed in a region where a resin member overlaps a metallic member.SOLUTION: A vehicle battery mounting structure 10 comprises: a fiber-reinforced resin lower frame 26 that has a first opening portion 27A for drainage and that constitutes, together with an upper frame 22, a battery frame 20 supporting a battery 16; a metallic lower reinforcement 46 that has a second opening 58A for drainage smaller in opening area than the first opening portion 27A and that is joined to the lower frame 26 in a state of communicating the second opening portion 58A with the first opening portion 27A; and a grommet 60 that is formed into a ring shape to have an upper flange 64 and a lower flange 66, that is provided in the lower reinforcement 46 by fitting a peripheral edge portion 58B constituting the second opening portion 58A of the lower reinforcement 46 between the upper flange 64 and the lower flange 66 and that exhibits insulation properties.SELECTED DRAWING: Figure 1 |
