A proposition is to provide a power transmitting mechanism for a hybrid vehicle having improved energy utilization efficiency. A power transmitting mechanism for the hybrid vehicle using powers of the engine and the motor/generator in a combined manner, the mechanism includes an engine drive shaft coupled to an engine output shaft via a main clutch; a motor output shaft of a motor/generator rotatably supported separately from the engine drive shaft; a drive shaft brake releasing/fixing the engine drive shaft; a motor-brake releasing/fixing the motor output shaft; and a planetary gear mechanism.
