Abstract
A suspension includes a housing, a radius arm, a radius arm bush, and a shock absorber. Inclination angles θ1 and θ2 satisfy ΔF·tan θ2>M·tan θ1, in which: θ1 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; θ2 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 ΔF 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.
