To provide an in-wheel motor type vehicle drive device which enables improvement of a speed reduction ratio.SOLUTION: This in-wheel motor type vehicle drive device 100 includes: a counter gear 21 having external teeth 21a which engage with external teeth 16a of a motor gear 16 of an electric motor 10; a planetary gear mechanism 101 to which driving force of the counter gear 21 is transmitted; and a hub 50 for transmitting driving force of the planetary gear mechanism 101 to a wheel 3 of a vehicle wheel 1. The planetary gear mechanism 101 is provided at a radial outer side of the counter gear 21, at least partially provided at an internal space 3a of the wheel 3, and includes: a first ring gear 24, a second ring gear 25, and a pinion gear 26 including a first gear part 27 which engages with the first ring gear 24 and the second gear part 28 which engages with the second ring gear 25 and has a diameter different from that of the first gear part 27.SELECTED DRAWING: Figure 1

    【課題】減速比を高めることが可能なインホイールモータ型の車両駆動装置を提供する。【解決手段】このインホイールモータ型の車両駆動装置100は、電気モータ10のモータギア16の外歯16aと噛み合う外歯21aを有するカウンタギア21と、カウンタギア21の駆動力が伝達される遊星歯車機構101と、遊星歯車機構101の駆動力を車輪1のホイール3に伝達するためのハブ50とを備える。そして、遊星歯車機構101は、カウンタギア21の径方向外側でかつ少なくとも一部がホイール3の内部空間3aに設けられ、第1リングギア24と、第2リングギア25と、第1リングギア24に噛み合う第1ギア部27と、第2リングギア25に噛み合うとともに第1ギア部27と直径の異なる第2ギア部28とを含むピニオンギア26と、を含む。【選択図】図1
