Abstract
A suspension apparatus supports a wheel of a vehicle which includes an in-wheel motor held by a carrier. A motor rotation axis of an output shaft of the in-wheel motor is located at a position identical in an up and down direction to or above a wheel rotation axis of the wheel. The suspension apparatus includes suspension arms coupled to the carrier holding the in-wheel motor. The suspension arms include first suspension arms each extending substantially in a widthwise direction of the vehicle. Each of the first suspension arms is coupled to a corresponding one of portions of the carrier which are located below the motor rotation axis. A first upper arm of the first suspension arms is coupled to a portion of the carrier which is located on an inner side of the in-wheel motor in the vehicle.
