摘要： A drive device includes a transmission in a housing, and a flow path. The transmission includes a shaft and a bearing supporting the shaft. The housing has a bearing holding portion that includes a facing surface on a first side in an axial direction with respect to an end on the first side of the shaft and orthogonal to the axial direction, and an inner surface extending from the facing surface to the other, second side in the axial direction and supporting the bearing. The flow path includes an inflow portion and an outflow portion below the inflow portion, both open to the inner surface. The facing surface has a rib protruding to the second side and orthogonal to the axial direction. At least a part of the rib is below the inflow portion, and at least a part of the rib covers the outflow portion from above.
