BATTERY MOUNTING STRUCTURE FOR VEHICLE

PROBLEM TO BE SOLVED: To provide a battery mounting structure for vehicles configured to prevent a cross member from being bent due to a side impact while preventing damage to a side member.SOLUTION: A height Hof a cross-side connection part 42 of a front cross member 40 is set to be lower than a height Hof a side connection part 32 of the side member 30. A central axis Cof the cross-side connection part 42 is positioned on the lower side in a vehicle vertical direction than a central axis Cof the side connection part 32. The side connection part 32 and the cross-side connection part 42 are connected by a connection member 50. A region of the cross-side connection part 42 covered with a low part 50C of the connection member 50 is a fragile part 42W with small flexural capacity. In an upper wall 42U and a lower wall 42L of the fragile part 42W, first positioning holes 62 are formed, respectively. The upper wall 42U and the lower wall 42L of the fragile part 42W are connected by a connection rod 60 passing through the first positioning holes 62.
