    Abstract: In a drive device, a first flow path of a fluid connects a gear accommodation portion and an inlet of a pump. A second flow path connects an outlet of the pump and one end of a third flow path via a cooler. The third flow path is inside a partition wall of a housing and intersects a rotation axis of a first shaft. A fourth flow path connects another end of the third flow path and one end of a fifth flow path. The fifth flow path is inside a gear side lid of the housing. Another end of the fifth flow path is connected to one end of a second shaft in an axial direction. One end of a sixth flow path is connected to another end of the third flow path. Another end of the sixth flow path is inside a housing tubular portion.
