1. A motor mount system comprising:
a motor unit that is disposed such that an output shaft thereof is along a vehicle width direction and generates a driving torque for vehicle travel;
four bush mounts to which reaction force of the driving torque is input in a vertical direction, two bush mounts thereof being disposed in front of the motor unit and two bush mounts thereof being disposed behind the motor unit, and central axes thereof being arranged so as to be along a vehicle front-rear direction; and
a frame that supports the motor unit via the four bush mounts, wherein
the four bush mounts have configurations that are identical to each other and are configured such that rigidity to a load in a direction orthogonal to the central axes changes along a circumferential direction, and
among the four bush mounts, a first bush mount is closest to a center of gravity of the reaction force input to the two bush mounts disposed in front of the motor unit, or a center of gravity of the reaction force input to the two bush mounts disposed behind the motor unit, a second bush mount is located at an opposing corner of the first bush mount in a rectangle having positions of the four bush mounts as apexes, and at least one of the first bush mount and the second bush mount is disposed in a state where at least one of the first bush mount and the second bush mount is rotated in a direction in which rigidity to the load in the vertical direction is higher than rigidity of other bush mounts.
