PROBLEM TO BE SOLVED: To provide a structure for stably supporting a final gear of a speed reduction part in an in-wheel motor drive device which reduces the speed of rotation of a motor part and transmits the rotation to a wheel hub bearing part.SOLUTION: A speed reduction part (31) includes an input shaft (32) connected to a motor rotating shaft (22) of a motor part (21), an input gear (33) connected to the input shaft, an output shaft (41) of a cylindrical shape connected to an outer ring (12), and an output gear (40) connected to the output shaft, and forms a drive transmission path that reduces the speed of rotation of the input gear and transmits the rotation to the output gear. Both ends of the output shaft are rotationally supported by a first output shaft bearing (44) rotationally supporting the outer diameter on one end side of the output shaft and by a second output shaft bearing (46) rotationally supporting the inner diameter on the other end side of the output shaft.SELECTED DRAWING: Figure 1

    【課題】モータ部の回転を減速して車輪ハブ軸受部に伝達するインホイールモータ駆動装置において、減速部の最終歯車を安定して支持する構造を提供する。【解決手段】減速部(31)は、モータ部(21)のモータ回転軸(22)と結合する入力軸(32)、入力軸と結合する入力歯車(33)、外輪(12)と結合する円筒形状の出力軸(41)、出力軸と結合する出力歯車(40)を含み、入力歯車の回転を減速して出力歯車に伝達する駆動伝達経路を構成する。そして出力軸の一方端側の外径を回転支持する第1出力軸軸受(44)と、出力軸の他方端側の内径を回転支持する第2出力軸軸受(46)とにより、出力軸の両端が回転支持される。【選択図】図1
