Abstract
A power system includes: an electric motor that drives wheels of a vehicle; a transmission that is disposed on power transmission paths between the electric motor and the wheels; and a differential gear system that distributes output power shifted by the transmission to the wheels. The transmission includes: a first gear mechanically connected to the electric motor; a second gear that has a rotation axis in common with the first gear and is mechanically connected to a differential gear casing of the differential gear system; a pinion gear that meshes with the first gear and the second gear; and a pinion holder that rotatably supports the pillion gear. The pinion holder has a pinion gear supporting portion which is disposed on a side of the differential gear casing to support the pinion gear, relative to a meshing portion between the second gear and the pinion gear.
