PROBLEM TO BE SOLVED: To provide a rear wheel steering device which can properly steer rear wheels by a simple constitution.SOLUTION: A rear wheel steering device 10 comprises: a rear axle housing 20 for supporting rear wheels 5 of a vehicle 1; a lower radius rod 50 which is arranged along a fore-and-aft direction of the vehicle 1, and connected to one end side of the rear axle housing 20 in an axial direction; a lower radius rod 55 which is arranged along the fore-and-aft direction, and connected to the other end side of the rear axle housing 20 in the axial direction; an actuator 60 for moving the lower radius rod 50 to the fore-and-aft direction; and a connecting member 72 which is connected to the lower radius rod 50 and the lower radius rod 55, and can turn with a pivot part 73 located at a center side in a vehicle width direction as a center. The connecting member 72 moves the lower radius rod 55 to a direction reverse to a moving direction of the lower radius rod 50 in the fore-and-aft direction by turning with the pivot part 73 as a center in conjunction with the movement of the lower radius rod 50 by the actuator 60, and turns the rear axle housing 20.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】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2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を前後方向に移動させるアクチュエータ60と、下方ラジアスロッド50と下方ラジアスロッド55に連結され、車幅方向の中央側に位置する支点部73を中心に回動可能な連結部材72と、を備え、連結部材72は、アクチュエータ60による下方ラジアスロッド50の移動に連動して支点部73を中心に回動することで、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
