A suspension includes a housing, suspension links, a spring, and a stabilizer. The housing rotatably supports a rear wheel of a vehicle. The suspension links each have both ends swingably coupled to a vehicle body of the vehicle and the housing. The spring is disposed between the vehicle body and one of the suspension links or the housing. The stabilizer includes a stabilizer bar and a stabilizer link. A force application point where force generated by the spring is applied to the housing is disposed on a rear side of the vehicle with respect to a center of the rear wheel. The stabilizer link is coupled to the housing to allow a force application point where force generated by the stabilizer is applied to the housing to be disposed on the rear side of the vehicle with respect to the center of the rear wheel.

Suspension

A suspension includes a housing, links, a radius arm, and a radius arm bush. The radius arm bush is provided on a front end of the radius arm, couples the radius arm to a vehicle body, with an elastic body in between, and is disposed vehicle-widthwise inwardly of a wheel center contact point of the rear wheel. The radius arm bush has higher rigidity with respect to turn of the radius arm with respect to the vehicle body in a direction in which an underside of the radius arm is displaced vehicle-widthwise outwardly from an upside of the radius arm, than rigidity with respect to turn of the radius arm with respect to the vehicle body in a direction in which the underside of the radius arm is displaced vehicle-widthwise inwardly from the upside of the radius arm.

A suspension includes a housing, a radius arm, a radius arm bush, and a shock absorber. Inclination angles &#x3b8;1 and &#x3b8;2 satisfy &#x394;F&#xb7;tan &#x3b8;2&#x3e;M&#xb7;tan &#x3b8;1, in which: &#x3b8;1 is an inclination angle at which a straight line coupling the center of the radius arm bush to the center of a rear wheel is inclined to a horizontal line, to lower toward the rear wheel, viewed from a side of the vehicle in a steady state; &#x3b8;2 is an inclination angle at which an axis of expansion and shrink of the shock absorber is inclined to a vertical direction, to allow the shock absorber's upper end to more forward from the shock absorber's lower end; M is an unsprung mass of the suspension; and &#x394;F is an amount of increase in a vertical load on the rear wheel from the steady state during a shrinkwise stroke of the shock absorber.
