There is provided a drive device for a vehicle. A forward clutch that is engaged during forward driving is provided in a power transmission path between an engine and a drive wheel. A spring is incorporated in an engagement oil chamber of the forward clutch, thereby causing the forward clutch to be held in a slipping state or an engaged state through the spring force even during an idling stop that suffers from reduced control oil pressure. This arrangement can prevent the forward clutch from producing an engagement shock during an engine restart. In addition, an input clutch driven by an electric actuator is provided in the power transmission path. With this arrangement, neutral control can be performed by disengaging the input clutch even if the forward clutch which is to be held in a slipping state or an engaged state is provided.

Drive device for vehicle

An orthogonal axis gear, a planetary gear reduction mechanism portion, and a differential gear mechanism portion are arranged along an axial center direction of left and right output shafts. The planetary gear reduction mechanism portion is constituted such that a sun gear thereof is provided as a continuation of a crown gear of the orthogonal axis gear, a ring gear thereof is fixed to a differential case, and a planetary carrier thereof serves as an output. Further, the differential gear mechanism portion employs a planetary gear mechanism and is constituted such that a ring gear of the planetary gear mechanism is provided as a continuation of the planetary carrier of the planetary gear reduction mechanism portion, a planetary carrier thereof is provided as a continuation of the left side output shaft, and a sun gear thereof is provided as a continuation of the right side output shaft.
