To provide a rear wheel steering device which can efficiently convert a motion, suppress power consumption during position movement of a rod, and reduce size of an electric motor, and a vehicle using the same.SOLUTION: A rear wheel steering device includes a rod movably supported in an axial direction and changes the direction of rear wheels according to movement of the rod in the axial direction. The rod is a rod of an electric actuator. A drive part of the electric actuator comprises: an electric motor generating rotational torque; a differential reduction gear reducing rotational speed; and a motion conversion mechanism including a ball screw mechanism converting rotational motion reduced by the differential reduction gear into linear motion of the rod.SELECTED DRAWING: Figure 1

    【課題】効率のよい運動変換が可能で、ロッドの位置移動時の消費電力を抑え、電動モータサイズのコンパクト化を図ることが可能な後輪操舵装置およびこれを用いた車両を提供する。【解決手段】軸方向に移動可能に支持されるロッドを備え、このロッドの軸方向の移動に応じて後輪の向きを変化させる後輪操舵装置である。ロッドは電動アクチュエータのロッドである。電動アクチュエータの駆動部は、回転トルクを発生させる電動モータと、回転速度を減速する差動減速機と、差動減速機に減速された回転運動を前記ロッドの直線運動に変換するボールねじ機構を有する運動変換機構とを備える。【選択図】図1
