Abstract

Abstract A hybrid vehicle driving device, wherein a motor generator (6) is disposed, with a specified clearance (C) provided between the motor generator and a rotor (43), on the outer diameter side of an intermediate portion (30b) at a position where at least a part of the motor generator is overlapped axially with a torque converter (5) and a rotor (43) is supported by one or a combination of two of the torque converter (5), a motor housing (15), and a crankshaft (52) except by the motor housing (15) only, whereby, by the presence of the space (C), the rotor (43) is not affected by the torque converter (5) on the outer diameter side and thus the efficiency of a motor will not be lowered.
