PROBLEM TO BE SOLVED: To properly lubricate a splined part between a support member and a carrier in the last stage.SOLUTION: On the axial direction one side of a rotary shaft 39, there provided a male spline on the rotation source side 39A1 which is splined to a driven gear 27 of a speed reduction mechanism 23 and a male spline on the oil reservoir space side 39A2 which extends in an oil reservoir space 21. On a fitting flange contact surface 48B of a nut member 48 that is screwed with a male screw 47F of a carrier 47 in the last stage, a plurality of oil passages 49 is provided. By this, a lubricant 52 stored in the oil reservoir space 21 is scooped up by a male spline on the oil reservoir space side 39A2 of the rotary shaft 39, and attached to an end surface 14C of a fitting flange 14 of a support member 12. This oil drop 52A flows down along the end surface 14C onto the outer peripheral surface of the nut member 48, and then, is supplied via the oil passages 49 of the nut member 48 to a splined part between the support member 12 and the carrier 47. 【課題】 支持部材と最終段のキャリアとのスプライン結合部を適正に潤滑する。【解決手段】 回転軸３９の軸方向一側に、減速機構２３の従動歯車２７にスプライン結合される回転源側雄スプライン部３９Ａ１と、油溜め空間２１内に延在する油溜め空間側雄スプライン部３９Ａ２とを設ける。また、最終段のキャリア４７の雄ねじ部４７Ｆに螺合するナット部材４８の取付フランジ当接面４８Ｂに、複数の油路４９を設ける。これにより、油溜め空間２１内に貯溜された潤滑油５２が、回転軸３９の油溜め空間側雄スプライン部３９Ａ２によって掻上げられ、支持部材１２の取付フランジ１４の端面１４Ｃに付着すると、この油滴５２Ａは、端面１４Ｃに沿ってナット部材４８の外周面まで流下した後、ナット部材４８の油路４９を通じて支持部材１２とキャリア４７とのスプライン結合部に供給される。【選択図】 図６
