## Abstract

An electric vehicle includes a dash panel, a master cylinder and an electrical unit. The master cylinder is arranged on a motor compartment side and the driver's seat side of the dash panel. The master cylinder is connected to a brake pedal in a vehicle passenger compartment. The electrical unit includes an inverter, a motor and a gearbox. The electrical unit is arranged side by side in the motor compartment in a left-right direction of the vehicle. The electrical unit is disposed in front of and below the master cylinder in the motor compartment in a front-rear direction of the vehicle.

## Claims

### Claim 1

An electric vehicle comprising:
a dash panel;
a master cylinder disposed on a motor compartment side and a driver's seat side of the dash panel, and connected to a brake pedal disposed in a vehicle passenger compartment interior; and
an electrical unit including an inverter, a motor, and a gearbox that are arranged side by side in a left-right direction of the vehicle in the motor compartment; and
a unit member positioned below the master cylinder and connected to each of a pair of side members arranged on both sides of the vehicle in the left-right direction in the motor compartment,
the electrical unit being located in the motor compartment in front of and below the master cylinder in a front-rear direction of the vehicle, or below the master cylinder so as to partially overlap with the master cylinder in the front-rear direction.

### Claim 2 (depends on 1)

The electric vehicle according to claim 1, wherein
the electrical unit is supported by the unit member from above by upper mounts at two locations on the left and right, and supported by a lower mount at a lower rear portion of the electrical unit, and
one of the upper mounts is arranged at the two locations on the left and right has a mounting element with a lower rigidity than a mounting element of the other of the upper mounts.

### Claim 3 (depends on 2)

The electric vehicle according to claim 2, wherein
the master cylinder and the gearbox are arranged diagonally opposite each other in the left-right direction of the vehicle, and
the mounting element of the upper mount of the upper mounts that is arranged on a gearbox side has a greater rigidity than the mounting element of the upper mount of the upper mounts that is arranged on an inverter side.

### Claim 4 (depends on 2)

The electric vehicle according to claim 2, wherein
the master cylinder and the gearbox are arranged on the same side in the left-right direction of the vehicle, and
the mounting element of the upper mount of the upper mounts that is arranged on a gearbox side has a greater rigidity than the mounting element of the upper mount of the upper mounts that is arranged on an inverter side.

### Claim 5 (depends on 3)

The electric vehicle according to claim 3, wherein
the gearbox is positioned in the left-right direction of the vehicle so as not to overlap the master cylinder.

### Claim 6 (depends on 5)

The electric vehicle according to claim 5, wherein
the master cylinder is positioned directly above one of the side members, and
the upper mount located on the driver's seat side of the upper mounts is arranged farther inward of the vehicle than the master cylinder in the left-right direction of the vehicle.

### Claim 7 (depends on 2)

The electric vehicle according to claim 2, wherein
the lower mount has a mounting element with a lower rigidity than the mounting element of the upper mount of the upper mounts having the greater rigidity.
