<P>PROBLEM TO BE SOLVED: To provide a hybrid drive device capable of efficiently cooling an electric motor by preventing a capacity of an oil pump from being increased and preventing fuel economy of the vehicle from being deteriorated. <P>SOLUTION: The hybrid drive device is provided with a driving electric motor 8 constituted so as to include a motor case 22 divided to case spaces G1, G2 by a partition wall 24 and an extension housing 23, a stator 15 fixed to the motor case so as to clamp the partition wall and wound with a winding wire 15b, and a rotor 12 fixed to a rotor shaft 13 rotatably provided on an inner peripheral part of the stator; a separator plate 30 fixed to an inner peripheral part in a radiation direction of the motor case so as to clamp the partition wall; and a friction plate 31 provided engageably/disengageably with the separator plate. A through hole 59 for communicating the case spaces is formed on the partition wall near the separator plate and the friction plate. <P>COPYRIGHT: (C)2009,JPO&INPIT |
