1. A hybrid vehicle comprising:
an engine including an engine internal space;
an electric motor;
a transmission that
includes an input shaft, an output shaft, a gear train located at the input shaft and the output shaft, and a transmission internal space in which the gear train is located, and
is configured to change speed of rotational power transmitted from the engine and the electric motor to the input shaft and output the rotational power to a driving wheel;
an oil pump configured to be driven by the rotational power from the engine and the electric motor;
an oil passage including:
a common oil passage configured to have lubricating oil discharged from the oil pump flow therethrough,
an engine lubricating oil passage extending from the common oil passage toward the engine internal space, and
a transmission lubricating oil passage extending from the common oil passage toward the transmission internal space; and
a variable throttle valve that is configured to change a flow rate in the transmission lubricating oil passage and increase an opening degree of the variable throttle valve in a mode transition in which a first traveling mode in which the hybrid vehicle travels by driving power of the engine transitions to a second traveling mode in which the hybrid vehicle stops the engine and travels by the driving power of the electric motor.
