Patent attributes
A drive device includes a first shaft, a gear portion, a lubricant flow path, and a housing. A gear portion having a second shaft is connected to an end portion of the first shaft in the axial direction. A side plate portion of the housing separates a motor tubular portion surrounding a motor accommodation portion that accommodates a rotor and a stator and a gear tubular portion surrounding a gear accommodation portion that accommodates the gear portion. First and second bearing holding portions disposed in the side plate portion rotatably support the first and second shafts via the first and second bearings, respectively. A lubricant supply portion that is disposed radially outward of the stator and supplies lubricant to the stator includes a lubricant flow path through which lubricant can flow. The lubricant flow path is connected to at least one of the first and second bearing holding portions.
