Abstract
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.
