To provide a compact rear wheel steering device.SOLUTION: A motor output shaft 28 is supported by a first bearing 23L having a rolling element 43 rolling along an inside raceway surface 41a and an outside raceway surface 42a, and a retainer 44 for retaining the rolling element 43. A planetary reduction gear is constituted of the first bearing by performing traction drive between the inside raceway surface 41a of the first bearing 23L and the rolling element 43, and between the outside raceway surface 42a and the rolling element 43. The reduction gear 23L is interposed on a torque transmission path between the motor output shaft 28 and a motion conversion mechanism 24L.SELECTED DRAWING: Figure 3

    【課題】 コンパクトな後輪操舵装置を提供する。【解決手段】 モータ出力軸28を、内側軌道面41aおよび外側軌道面42aを転動する転動体43と、転動体43を保持する保持器44とを有する第1軸受23Lで支持する。第1軸受23Lの内側軌道面41aと転動体43の間、および外側軌道面42aと転動体43との間でトラクションドライブを行うことにより第1軸受で遊星減速機を構成する。この減速機23Lを、モータ出力軸28と運動変換機構24Lとの間のトルク伝達経路に介在させる。【選択図】図3
