Zusammenfassung:To provide a driving device which enables improvement of cooling performance of a motor by using oil.SOLUTION: Each of driving units 6A, 6B of a driving device 4 includes: a motor 8 which rotates front wheels 5A, 5B; a counter gear 9 which rotates in response to rotation of an output shaft 16 of the motor 8; a counter gear 10 which engages with the counter gear 9; a planetary gear mechanism 11 which transmits rotation of the counter gear 10 to the front wheels 5A, 5B; and a housing 12 which houses the motor 8, the counter gears 9, 10, and the planetary gear mechanism 11 and in which oil for lubricating the counter gears 9, 10 and the planetary gear mechanism 11 is accumulated. An oil passage 33 in which the oil scraped by the counter gears 9, 10 is provided between the counter gears 9, 10 in the housing 12. An oil passage 34 in which the oil that has flowed through the oil passage 33 flows is provided between the planetary gear mechanism 11 and the motor 8 in the housing 12.SELECTED DRAWING: Figure 4 【課題】オイルを用いてモータの冷却性能を向上させることができる駆動装置を提供する。【解決手段】駆動装置4の駆動ユニット6A,6Bは、前輪5A,5Bを回転させるモータ8と、モータ8の出力軸16の回転に応じて回転するカウンタギア9と、カウンタギア9と噛み合うカウンタギア10と、カウンタギア10の回転を前輪5A,5Bに伝達する遊星歯車機構11と、モータ8、カウンタギア9,10及び遊星歯車機構11を収容すると共に、カウンタギア9,10及び遊星歯車機構11を潤滑するためのオイルが溜められる筐体12と、を備え、筐体12におけるカウンタギア9,10の間には、カウンタギア9,10により掻き上げられたオイルが流れるオイル流路33が設けられており、筐体12における遊星歯車機構11とモータ8との間には、オイル流路33を流れたオイルが流れるオイル流路34が設けられている。【選択図】図4
