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.

Suspension

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.

A steering apparatus includes an actuator and an actuator controller. The actuator is configured to generate an output for turning a steerable wheel of a vehicle. The actuator controller is configured to control the actuator in accordance with a steering input. The actuator controller includes a filtering processor configured to perform filtering processing for reducing or cutting a component in a predetermined frequency band from the steering input, and the actuator controller is configured to control the actuator in accordance with the steering input after the filtering processing.
