1. A suspension device for a vehicle equipped with an electric motor for transmitting a drive force to at least one of a front wheel or a rear wheel via an output transmission shaft, the suspension device comprising:
a front suspension arm capable of swinging in a vehicle up-down direction with reference to a front wheel swinging axis in a vehicle body-side mounting portion in a front portion of the vehicle;
a front damper having a longitudinal axis which extends in a direction perpendicular to the front wheel swinging axis in a side view;
a rear suspension arm capable of swinging in the vehicle up-down direction with reference to a rear wheel swinging axis in a vehicle body-side mounting portion in a rear portion of the vehicle; and
a rear damper having a longitudinal axis which extends in a direction perpendicular to the rear wheel swinging axis in a side view, wherein
the front wheel swinging axis and a first imaginary line perpendicular to a direction of extension of the longitudinal axis of the front damper extend in a direction parallel to each other and the rear wheel swinging axis and a second imaginary line perpendicular to a direction of extension of the longitudinal axis of the rear damper extend in a direction parallel to each other in a side view;
the suspension device includes front and rear wheel hub carriers to which wheel-side end portions of the front suspension arm and the rear suspension arm are respectively coupled and which respectively support the front wheel and the rear wheel; and
the longitudinal axis of the front damper is aligned with a center of the front wheel hub carrier in the side view and the longitudinal axis of the rear damper is aligned with a center of the rear wheel hub carrier in the side view.
