Abstract
A vehicle drive unit with a support apparatus is provided which can provide both low rigidity in the translational direction at the center of gravity and high rigidity with respect to moment input caused by the drive shaft at the center of gravity. The low rigidity in the translational direction at the center of gravity provided by the support apparatus is required for vibration control. The high rigidity in the translational direction at the center of gravity provided by the support apparatus is required for controlling the jerking vibration that occurs during acceleration from a standstill. The support apparatus is preferably designed to support a drive unit with an integrated reduction gear. The support apparatus has multiple elastic mounting members in a vehicle for which at least the front wheels or the rear wheels are driven by an electric motor or the like. Preferably, the elastic mounting members that support the drive unit are at least three in number and arranged within the same plane. The elastic centers of the elastic mounting members are set so as to be contained within one plane. This plane is set so that when it is used as the mounting plane, two of the inertial axes of the drive unit lie within the mounting plane.
