## Abstract

A corrugated plate portion of a core panel is sandwiched between an upper panel and a lower panel, and is formed in a shape in which upwardly-facing concave portions, that open toward a side of the upper panel and extend in a vehicle transverse direction, and downwardly-facing concave portions, that open toward a side of the lower panel and extend in the vehicle transverse direction, are lined-up alternately. A sum of contact surface areas of the upper panel and bottom wall portion sides of the downwardly-facing concave portions at the corrugated plate portion is smaller than a sum of contact surface areas of the lower panel and bottom wall portion sides of the upwardly-facing concave portions at the corrugated plate portion.

## Claims

### Claim 1

A battery mounting structure for a vehicle, comprising:
a battery frame that is disposed at a vehicle body lower side of a floor panel, and that supports a battery for vehicle driving from a lower side,
wherein the battery frame has:
an upper plate portion that is made of resin,
a lower plate portion that is made of resin and is disposed at a lower side of the upper plate portion, and
a corrugated plate portion that is made of resin and is sandwiched between the upper plate portion and the lower plate portion, the corrugated plate portion having upwardly-facing concave portions, that open toward a side of the upper plate portion and extend in one direction, and downwardly-facing concave portions, that open toward a side of the lower plate portion and extend in the one direction, and the upwardly-facing concave portions and the downwardly-facing concave portions being lined-up alternately; and
wherein a sum of contact surface areas of the upper plate portion and bottom wall portion sides of the downwardly-facing concave portions at the corrugated plate portion is smaller than a sum of contact surface areas of the lower plate portion and bottom wall portion sides of the upwardly-facing concave portions at the corrugated plate portion.

### Claim 2 (depends on 1)

The battery mounting structure for a vehicle of claim 1, wherein an opening width of the upwardly-facing concave portion as seen in the one direction is wider than a contact width of the upper plate portion and the bottom wall portion side of the downwardly-facing concave portion.

### Claim 3 (depends on 2)

The battery mounting structure for a vehicle of claim 2, wherein an opening width of the downwardly-facing concave portion as seen in the one direction is narrower than the opening width of the upwardly-facing concave portion.
