## Abstract

A vehicle-body front structure includes a partition wall portion which demarcates a space inside a vehicle cabin, a motor arrangement portion which is formed by causing a part of the partition wall portion to bulge to an inside of the vehicle cabin and in which at least a part of a traveling motor is capable of being arranged, a reinforcement member which is inclined to be positioned lower toward vehicle rear, and a floor reinforcement which extends in a vehicle front-rear direction. A closed cross-section is configured with the motor arrangement portion, the reinforcement member, and the floor reinforcement.

## 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;
a motor arrangement portion which is formed by causing a part of the partition wall portion to bulge to an inside of a vehicle cabin and in which at least a part of the traveling motor installed on an outside of the vehicle cabin inside space is capable of being arranged;
a reinforcement structure which extends from an upper portion of the motor arrangement portion to vehicle rear and is inclined to be positioned lower toward the vehicle rear; and
a floor reinforcement which extends in a vehicle front-rear direction below the reinforcement structure and along a floor panel, wherein
a first closed cross-section is configured with the motor arrangement portion, the reinforcement structure, and the floor reinforcement.

### Claim 2 (depends on 1)

The vehicle-body front structure according to claim 1, wherein
a connecting structure, which couples a front portion of the reinforcement structure and a front portion of the floor reinforcement together in an up-down direction, is provided in the vehicle rear of the motor arrangement portion.

### Claim 3 (depends on 2)

The vehicle-body front structure according to claim 2, wherein
a second closed cross-section is configured with the connecting structure and the motor arrangement portion.

### Claim 4 (depends on 3)

The vehicle-body front structure according to claim 3, comprising
a cross structure which is fixed to the floor panel on a vehicle rear side of the motor arrangement portion and extends in the vehicle width direction, wherein
a rear portion of the floor reinforcement is connected with an intermediate portion of the cross structure in the vehicle width direction.

### Claim 5 (depends on 4)

The vehicle-body front structure according to claim 4, wherein
a front portion of the floor reinforcement is connected with a lower portion of the motor arrangement portion.

### Claim 6 (depends on 1)

The vehicle-body front structure according to claim 1, comprising
a cross structure which is fixed to the floor panel on a vehicle rear side of the motor arrangement portion and extends in the vehicle width direction, wherein
a rear portion of the floor reinforcement is connected with an intermediate portion of the cross structure in the vehicle width direction.

### Claim 7 (depends on 1)

The vehicle-body front structure according to claim 1, wherein
a front portion of the floor reinforcement is connected with a lower portion of the motor arrangement portion.

### Claim 8 (depends on 2)

The vehicle-body front structure according to claim 2, comprising
a cross structure which is fixed to the floor panel on a vehicle rear side of the motor arrangement portion and extends in the vehicle width direction, wherein
a rear portion of the floor reinforcement is connected with an intermediate portion of the cross structure in the vehicle width direction.

### Claim 9 (depends on 2)

The vehicle-body front structure according to claim 2, wherein
a front portion of the floor reinforcement is connected with a lower portion of the motor arrangement portion.

### Claim 10 (depends on 3)

The vehicle-body front structure according to claim 3, wherein
a front portion of the floor reinforcement is connected with a lower portion of the motor arrangement portion.
