## Abstract

A vehicle-body front structure includes a partition wall portion which demarcates a space inside a vehicle cabin and a pair of left and right suspension tower portions which are formed to bulge inward in the vehicle width direction and support upper portions of front suspension apparatuses. A lower-side portion of the partition wall portion is formed to be positioned further to vehicle rear toward a lower position. A traveling motor is installed below the lower-side portion of the partition wall portion. An upper-side portion of the partition wall portion extends from an intermediate portion of the left suspension tower portion in a vehicle front-rear direction to an intermediate portion of the right suspension tower portion in the vehicle front-rear direction.

## Claims

### Claim 1

A vehicle-body front structure for an electric vehicle in which a traveling motor is installed in a vehicle front portion, the vehicle-body front structure comprising:
a partition wall portion which is provided to extend in a vehicle width direction in the vehicle front portion and demarcates a vehicle cabin inside space; and
a pair of left and right suspension tower portions which are formed to bulge inward in the vehicle width direction and support upper portions of front suspension apparatuses, wherein
a lower-side portion of the partition wall portion is formed to be positioned further to a vehicle rear toward a lower position compared to an upper-side portion of the partition wall portion,
the traveling motor is installed below the lower-side portion of the partition wall portion, and
the upper-side portion of the partition wall portion extends from an intermediate portion of the left suspension tower portion in a vehicle front-rear direction to an intermediate portion of the right suspension tower portion in the vehicle front-rear direction.

### Claim 2 (depends on 1)

The vehicle-body front structure according to claim 1, wherein
the partition wall portion includes a first partition wall portion corresponding to the upper-side portion and a second partition wall portion corresponding to the lower-side portion, and
the first partition wall portion extends from an intermediate portion of the left suspension tower portion in the vehicle front-rear direction to an intermediate portion of the right suspension tower portion in the vehicle front-rear direction.

### Claim 3 (depends on 2)

The vehicle-body front structure according to claim 2, comprising
a motor arrangement portion which is formed by causing a part of the second partition wall portion to bulge to an inside of a vehicle cabin and in which at least a part of the traveling motor is capable of being arranged.

### Claim 4 (depends on 3)
