PROBLEM TO BE SOLVED: To maintain lubrication at sliding parts, which is a problem peculiar to a cycloidal speed reducer of an in-wheel motor drive unit.SOLUTION: An internal space of a decelerating part (B) accommodates revolving members (26a, 26b) that perform a revolution motion about an axis (O) of an input shaft of the deceleration part, are exposed to an oil atmosphere, and are attached to the outer peripheries of eccentric parts (25a, 25b) in a relatively rotatable manner, and are rotated with the rotation of the deceleration part input shaft (25), and plates (29, 46a, 46b) which slidably contact end faces of the revolving members. Numerous recesses (26d) for holding oil droplets are formed on at least one of the end faces of the revolving members and the end faces of the plates which are brought into sliding contact with each other.SELECTED DRAWING: Figure 4

    【課題】インホイールモータ駆動装置のサイクロイド減速機に特有の課題である、摺動箇所における潤滑を持続させる。【解決手段】減速部(B)の内部空間は、油雰囲気にされて、偏心部(25a,25b)の外周に相対回転可能に取り付けられて減速部入力軸(25)の回転に伴って減速部入力軸の軸線(O)を中心とする公転運動を行う公転部材(26a,26b)と、公転部材の端面に摺接するプレート(29,46a,46b)とを収容する。互いに摺接する公転部材の端面およびプレートの端面のうち少なくとも一方には、油滴を保持する無数の凹部(26d)が形成される。【選択図】図4
