PROBLEM TO BE SOLVED: To provide technique for reducing vibration or partial contact in an inside of an in-wheel motor drive device.SOLUTION: An in-wheel motor drive device (21) includes an input shaft (25) having a plurality of eccentric parts (25a and 25b) provided at different positions in a direction of an axis (O), a plurality of revolving members (26a and 26b) supported by the eccentric parts to be relatively rotatable and revolving around the axis of the input shaft along with the rotation of the input shaft, an outer periphery engaging member (27) engaged with an outer periphery of the revolving members to generate rotation motion of the revolving members, motion converting mechanisms (28 and 31) for converting the rotation motion of the revolving members to turning motion around the axis of the input shaft to be output, and an axial direction pressing member (29) disposed between the adjacent two revolving members (26a and 26b) and pressing the one revolving member and the other revolving member so as to separate from each other in the axial direction.
【課題】インホイールモータ駆動装置内部の振動や片当たりを低減させる技術を提供する。【解決手段】インホイールモータ駆動装置(21)は、軸線(O)方向に異なる位置に設けられた複数の偏心部(25a,25b)を有する入力軸(25)と、各偏心部に相対回転可能に保持され入力軸の回転に伴って該入力軸の軸線を中心とする公転運動を行う複数の公転部材(26a,26b)と、公転部材の外周に係合して公転部材の自転運動を生じさせる外周係合部材(27)と、公転部材の自転運動を入力軸の軸線を中心とする回転運動に変換して出力する運動変換機構(28,31)と、隣り合う2個の公転部材(26a,26b)間に配置され、一方の公転部材と他方の公転部材とを軸線方向に離間するように押圧する軸方向押圧部材(29)とを備える。【選択図】図1
