Suspension device for non-steered driving wheel incorporating in-wheel motor

A suspension device for a non-steered driving wheel which is rotationally driven by an in-wheel motor incorporated in a wheel carrier, the suspension device comprising a suspension arm pivotally supported on a vehicle body of a vehicle and connected to the wheel carrier by a connecting structure, wherein

• the connecting structure chides a plate member fixed to the wheel carrier by fastening at positions spaced in a front-rear direction of a vehicle, and a pair of elastic bushing devices attached to the plate member in a state of being inserted through the plate member at positions spaced in the front-rear direction of the vehicle;
• the suspension arm has open cross sectional portions which each receive a portion of the plate member and the elastic bushing device;
• and
• the elastic bushing devices are fixed to the open cross sectional portions at both ends, and
• the vehicle includes a pair of the non-steered driving wheels spaced laterally and a vehicle tilting device configured to tilt the vehicle to a turning inner side when the vehicle turns, and the vehicle tilting device includes a swing member that swings about a swing axis extending in the front-rear direction, an actuator that swings the swing member about the swing axis, and a pair of connecting rods pivotally connected to the swing member at upper end pivot points and pivotally connected to the corresponding wheel carriers at lower end pivot points on both lateral sides with respect to the swing axis.
