Abstract

In a battery mounting structure for a vehicle that includes a battery box mounted on an under-floor side of a vehicle body floor, the battery box includes: a battery pan on which a battery is placed; an outer peripheral frame formed to project from an outer peripheral edge portion of the battery pan; a cover placed on the battery pan from above; and sealing means provided in a joint portion between the battery pan and the cover, wherein the sealing means is disposed above the outer peripheral frame and positioned further inside than an outer periphery of the outer peripheral frame in plan view.

Claims

1. A battery mounting structure for a vehicle, which includes a battery box that is mounted on an under-floor side of a vehicle body floor,

wherein said battery box has:

a battery pan on which a battery is placed;

an outer peripheral frame formed to project from an outer peripheral edge portion of said battery pan;

a cover placed on said battery pan from above; and

sealing means provided in a joint portion between said battery pan and said cover; and

wherein said sealing means being disposed above said outer peripheral frame and positioned further inside than an outer periphery of said outer peripheral frame in plan view.

2. The battery mounting structure for a vehicle according to claim 1, wherein a guard portion for concealing said sealing means from the outside of the a vehicle in cooperation with said outer peripheral frame is formed on an outer peripheral edge portion of at least one of said cover and said battery pan.

3. The battery mounting structure for a vehicle according to claim 1, wherein said sealing means in a front end portion of said battery box is disposed on a rear side of a cross member that is provided on said vehicle body so as to extend in a vehicle width direction, and a part of said outer peripheral frame is disposed under a gap between said cross member and said sealing means.

4. The battery mounting structure for a vehicle according to claim 3, comprising a stay for connecting said front end portion of said battery box to said cross member.

5. The battery mounting structure for a vehicle according to claim 1, wherein said sealing means has:

a seal member formed from an elastic material; and

a battery pan side flange and a cover side flange opposing each other, with said seal member interposed therebetween, and further has;

a clamp that sandwiches said battery pan side flange and said cover side flange using a spring force; and

a dropping-off prevention plate which is provided between an upper surface of said cover side flange and said clamp, and which engages respectively with said cover side flange and said clamp to prevent said clamp from dropping off.
