PROBLEM TO BE SOLVED: To provide a rear wheel steering device which is interposed in a suspension mechanism so as to steer rear wheels and can properly absorb vibration in a radial direction of a rod.SOLUTION: A rear wheel steering device of a vehicle includes: an electric motor stored in a housing; a speed reduction mechanism; and a direct-acting mechanism. The direct-acting mechanism has a nut member 36 and a rod 2 and converts a rotary motion of the nut member to a linear motion of the rod. The rod is screwed to the nut member and has one end connected to a second connection member (ball joint) and the other end which is extended from the nut member and is defined as a free end. An annular member 2x is held at the free end with a clearance in an axial direction and a radial direction of the rod. For example, a nut 2d is screwed to the free end of the nut member, the annular member 2x is fitted to the cylindrical body section 2da, and a snap ring 2y is locked to the cylindrical body section.SELECTED DRAWING: Figure 5

    【課題】サスペンション機構に介装し後輪を操舵する後輪操舵装置において、ロッドの径方向の振動を適切に吸収し得る装置を提供する。【解決手段】ハウジング内に収容する電動モータ、減速機構及び直動機構を備え、直動機構はナット部材36及びロッド2を有し、ナット部材の回転運動をロッドの直線運動に変換する。ロッドはナット部材に螺合すると共に、一方の端部を第2の連結部材(ボールジョイント)に連結し、他方の端部をナット部材から延出して自由端部とする。この自由端部に、環状部材2xをロッドの軸方向及び径方向に間隙を以って保持する。例えば、ナット部材の自由端部にナット2dを螺着し、その筒体部2daに環状部材2xを嵌合しスナップリング2yを筒体部に係止する。【選択図】図5
