## Abstract

A vehicle motor includes: a motor housing; a rotation shaft disposed to protrude from opposite side surfaces of one end portion of the motor housing so as to be rotatable; and a plurality of mount sections being configured to fix the motor housing to a vehicle frame at opposite lateral sides, in which the plurality of mount sections include a plurality of mounting bosses fixed to the vehicle frame side via a fastening member, the plurality of mounting bosses include first and second mounting bosses disposed to be spaced apart from each other in a vertical direction, and third and fourth mounting bosses disposed to be spaced apart in a left-right direction from an imaginary line connecting the first and the second mounting bosses to each other are disposed to be spaced apart from each other in the vertical direction between the first and the second mounting bosses.

## Claims

### Claim 1

A vehicle motor, comprising:
a motor housing extending in a front-rear direction of a vehicle;
a rotation shaft disposed to protrude from opposite side surfaces of one end portion of the motor housing in a direction orthogonal to the extending direction of the motor housing, so as to be rotatable, the rotation shaft being configured to output a rotational force of a rotor within the motor housing; and
a plurality of mount sections disposed on opposite side surfaces of another end portion of the motor housing, the opposite side surfaces of the another end portion extending in the front-rear direction of the vehicle, the plurality of mount sections being configured to fix the motor housing to a vehicle frame at each of opposite lateral sides, wherein
the plurality of mount sections include a plurality of mounting bosses fixed to the vehicle frame side via a fastening member in a direction parallel to the rotation shaft, and
the plurality of mounting bosses include
first and second mounting bosses disposed to be spaced apart from each other in a vertical direction on each of the opposite side surfaces of the another end portion, and
third and fourth mounting bosses disposed to be spaced apart in a left-right direction from an imaginary line connecting the first and the second mounting bosses to each other and disposed to be spaced apart from each other in the vertical direction between the first and the second mounting bosses.

### Claim 2 (depends on 1)

The vehicle motor according to claim 1, wherein
the third mounting boss and the fourth mounting boss are disposed to sandwich the imaginary line.

### Claim 3 (depends on 1)

The vehicle motor according to claim 1, wherein
each of the third mounting boss and the fourth mounting boss is partially disposed on an identical horizontal line.

### Claim 4 (depends on 1)

The vehicle motor according to claim 1, wherein
the imaginary line is a tangent of an imaginary circle around the rotation shaft.
