To provide a rear wheel steering device capable of achieving smooth motor driving and excellent quietness.SOLUTION: A rear wheel steering device S includes: a first connection part J1 and a second connection part J2 mounted over a member on wheel side and a member on vehicle body side and installed on both ends thereof, of a suspension mechanism supporting rear wheels of a vehicle; a cylindrical housing 1 extending from the first connection part J1; a rod 2 extending from the second connection part J2 and reciprocatable on the same axial center as an axial center X of the housing 1 inside the housing 1; a motor M installed inside the housing 1 to drive the rod 2; a deceleration part 5 which decelerates a rotational speed of an output shaft 41 of the motor M and simultaneously transforms the rotation into reciprocation of the rod 2; a cover 6 which is disposed inside the housing 1, partitions between the motor M and the deceleration part 5 and has bearings supporting the output shaft 41; and a vibration control member 8 for suppressing mutual vibration transmission between the cover 6 and the housing 1.SELECTED DRAWING: Figure 1
【課題】モータの駆動が円滑で静寂性に優れた後輪操舵装置を得る。【解決手段】車両の後輪を支持するサスペンション機構のうち、車輪の側の部材と、車体の側の部材とに亘って取り付けられ、両端に設けられた第1連結部J1および第2連結部J2と、第1連結部J1から延出する筒状のハウジング1と、第2連結部J2から延出して前記ハウジング1の内部でハウジング1の軸芯Xと同一軸芯上に往復移動可能なロッド2と、ハウジング1の内部に設けられてロッド2を駆動するモータMと、モータMの出力軸41の回転速度を減速しつつ当該回転をロッド2の往復移動に変換する減速部5と、ハウジング1の内側に配置され、モータMと減速部5との間を仕切ると共に、出力軸41を支持する軸受を有するカバー6と、を備え、カバー6とハウジング1との間に、互いの振動伝達を抑制する防振材8が設けられている後輪操舵装置S。【選択図】図1
