In a vehicular hybrid drive system including an engine, a first rotary machine that is mechanically connected to the engine and is used at least as a generator, a belt-and-pulley continuously variable transmission to which output of the engine and the first rotary machine is transmitted via an input shaft, and a clutch device that permits and interrupts power transmission between the belt-and-pulley continuously variable transmission and driving wheels, and a second rotary machine that is used at least as an electric motor, and is arranged to cause a vehicle to run even when the engine is stopped, an input pulley of the belt-and-pulley continuously variable transmission is disposed coaxially with the engine, and is mechanically connected to the engine via the input shaft, such that the input pulley is rotated and stopped along with the engine at all times.
