PROBLEM TO BE SOLVED: To reduce a cost of an in-wheel motor drive unit, and to improve the durability of the in-wheel motor drive unit.SOLUTION: In an in-wheel motor drive unit 21 which is composed of a cycloid reduction mechanism having a reduction gear input shaft 25 in which a reduction part B has eccentric parts 25a, 25b, and curved plates 26a, 26b which are rotatably held to external peripheries of the eccentric parts 25a, 25b of the reduction gear input shaft 25, and perform rotation motions, the curved plates 26a, 26b are formed of case hardening steel, and have hardened layers H which are formed by being applied with carburization quenching and tempering.

    【課題】インホイールモータ駆動装置の低コスト化および耐久性向上を図る。【解決手段】減速部Bが、偏心部25a,25bを有する減速機入力軸25と、減速機入力軸25の偏心部25a,25bの外周に回転自在に保持されて公転運動を行う曲線板26a,26bとを有するサイクロイド減速機構からなるインホイールモータ駆動装置21において、曲線板26a,26bが肌焼き鋼で形成され、浸炭焼入れ焼戻しが施されることにより形成された硬化層Hを有する。【選択図】図5
