Abstract
A vehicle driving apparatus includes a rotating electrical machine and an engagement device, which are disposed on a power transmission path linking an input member drive-coupled to an internal combustion engine and an output member drive-coupled to a wheel. The engagement device includes an engagement input coupled to the input member, an engagement output that forms a pair with the engagement input and is coupled to the rotating electrical machine, a friction member disposed between the engagement input and the engagement output, and a pressing member that presses the friction member in a pressing direction. An oil pressure chamber is formed between the pressing member and either the engagement input or the engagement output. A biasing spring biases the pressing member in the pressing direction when no oil pressure is supplied to the oil pressure chamber and is disposed on an exterior of the oil pressure chamber.
