PROBLEM TO BE SOLVED: To provide an in-wheel motor drive showing superior quietness and durability in which vibration or noise generated at a speed reducer is reduced.SOLUTION: This invention relates to an in-wheel motor drive 21 constituted by a motor part A, a speed reducer part B, and a wheel bearing part C. The speed reducer part B has a speed reducer input shaft 25 having eccentric parts 25a, 25b and rotationally driven by the motor part A; curved line plates 26a, 26b rotatably held at the outer peripheries of the eccentric parts 25a, 25b through a cylindrical roller bearing 41 so as to perform a revolving motion around a center of its rotating axial center as the speed reducer input shaft 25 is rotated; and a motion converting mechanism for converting a rotation movement generated at the curved line plates 26a, 26b during the revolving motion into a rotating motion of a speed reducer output shaft 28. The cylindrical roller 44 constituting the cylindrical roller bearing 41 has a crowning processing at its outer peripheral surface.SELECTED DRAWING: Figure 1

    【課題】 減速機部で発生する振動や騒音を低減し、静粛性および耐久性に優れたインホイールモータ駆動装置を提供する。【解決手段】 モータ部A、減速機部Bおよび車輪用軸受部Cを構成されたインホイールモータ駆動装置21であって、減速機部Bは、偏心部25a,25bを有し、モータ部Aにより回転駆動される減速機入力軸25と、偏心部25a,25bの外周に円筒ころ軸受41を介して回転自在に保持され、減速機入力軸25の回転に伴ってその回転軸心を中心とする公転運動を行う曲線板26a,26bと、公転運転中の曲線板26a,26bに生じる自転運動を減速機出力軸28の回転運動に変換する運動変換機構とを備え、円筒ころ軸受41を構成する円筒ころ44は、その外周面にクラウニングが施されている。【選択図】 図1
