PROBLEM TO BE SOLVED: To provide a simply-configured vehicular rear-wheel steering apparatus capable of steering a rear wheel properly.SOLUTION: A rear-wheel steering apparatus 10 for a vehicle 1 includes: a rear axle housing 20 for supporting a rear wheel 5 of the vehicle 1; a lower radius rod 50 disposed along a front-rear direction of the vehicle 1 and connected to one side of the rear axle housing 20 in an axial direction; a lower radius rod 55 disposed along the front-rear direction and connected to another side of the rear axle housing 20 in the axial direction; an actuator 60 for causing an actuation lever 52 to move the lower radius rod 50 in a front-rear direction, the actuation lever connected to the lower radius rod 50; and a connection mechanism 70 constituted by plural link structures that connect the actuation lever 52 to the lower radius rod 55. Further, the connection mechanism 70 rotates in association with a movement of the lower radius rod 50 by the actuator 60 to move the lower radius rod 55 in a direction reverse to the movement direction of the lower radius rod 50 in the front-rear direction, thus causing the rear axle housing 20 to rotate.SELECTED DRAWING: Figure 2

    【課題】簡易な構成で後輪を適切に操舵可能な後輪操舵装置を提供する。【解決手段】車両1の後輪操舵装置10は、車両1の後輪5を支持するリヤアクスルハウジング20と、車両1の前後方向に沿って設けられ、リヤアクスルハウジング20の軸方向一端側と連結されている下方ラジアスロッド50と、前後方向に沿って設けられ、リヤアクスルハウジング20の軸方向他端側と連結されている下方ラジアスロッド55と、下方ラジアスロッド50に連結された作動レバー52に、下方ラジアスロッド50を前後方向に移動させるための動力を発生するアクチュエータ60と、作動レバー52と下方ラジアスロッド55とを連結している複数のリンク構造から成る連結機構70と、を備え、連結機構70は、アクチュエータ60による下方ラジアスロッド50の移動に連動して回動することで、前後方向における下方ラジアスロッド50の移動方向とは逆方向に下方ラジアスロッド55を移動させて、リヤアクスルハウジング20を旋回させる。【選択図】図2
