In a vehicular drive system for a hybrid vehicle, in which driving forces of an engine and a motor are transmitted through a power transmission mechanism to driven wheels, a common oil stored in a transmission case and a motor case is used for lubricating the power transmission mechanism and the motor. During travel by means of an engine, when a synchromesh mechanism operated by a shift fork isolates the motor from the power transmission mechanism, an oil return hole blocking rod, provided in the shift fork, blocks an oil return hole providing communication between the motor case and the transmission case, thereby preventing oil in the motor case from flowing into the transmission case, to lower oil level in the transmission case. Thus, during travel of the hybrid vehicle, driving force loss due to motor drag resistance and oil stirring resistance is minimized.
