PROBLEM TO BE SOLVED: To make it possible to simultaneously adjust both of a camber angle and a toe angle with a single actuator.SOLUTION: A rear wheel suspension device is equipped with a single actuator 10 which drives pushing and pulling of a knuckle 4 in a substantially vehicle width direction, a damper 8 for giving an attenuation force to a lower arm LA, and a spring 9 for giving an elastic force to the lower arm LA. The knuckle 4 is connected to the lower arm LA via connection parts 11, 12 which enable rotation of a rear wheel 3 in a direction of changing a camber angle and a toe angle, a rotary shaft A regulated by the connection parts 11, 12 is so inclined by an angle α with respect to a vehicle body longitudinal direction that a vehicle body front side is positioned on an upper side in a side view in a vehicle stationery state, and the angle α is so set as to be reduced when the spring 9 and the damper 8 are contracted in a side view in a vehicle running state. Further, the rotary shaft is so set as to be inclined by an angle β with respect to the vehicle body longitudinal direction so that the vehicle body front side is positioned on a vehicle body outer side in a plan view in the vehicle stationery state.SELECTED DRAWING: Figure 2

    【課題】単一のアクチュエータでキャンバ角及びトー角の両方を同時に調整すること。【解決手段】ナックル4を略車幅方向に押し引き駆動する単一のアクチュエータ10と、ロアアームLAに対して減衰力を付与するダンパ8と、ロアアームLAに対して弾性力を付与するスプリング9とを備え、ナックル4は、後輪3のキャンバ角及びトー角を変更する向きの回動を可能とする連結部11、12を介してロアアームLAに連結され、連結部11、12により規定される回動軸Aは、車両静止状態で側面視して車体前側が上側に位置するように車体前後方向に対して角度αだけ傾斜すると共に、車両走行状態で側面視してスプリング9及びダンパ8が縮んだときに角度αが小さくなるように設定され、さらに、車両静止状態で平面視して車体前側が車体外側に位置するように車体前後方向に対して角度βだけ傾斜するように設定されている。【選択図】図2
