Abstract
A lubricating structure for a speed reducer includes: a case; an electric motor arranged inside the case; a reduction gear configured to rotate interlocking with an output shaft of the electric motor; a pair of drive axles configured to be driven to rotate by torque transmitted from the electric motor via the reduction gear; and a catch tank configured to store part of oil by scooping up the oil with the use of the reduction gear. The reduction gear is located on a front side of the vehicle with respect to a rotor of the electric motor, and is arranged such that a lower-side common tangent of an outer peripheral circle of the reduction gear and an outer peripheral circle of the rotor is inclined upward from the front side of the vehicle toward a rear side of the vehicle at a predetermined angle with respect to a horizontal line.
