A hybrid power unit is mounted on a vehicle body frame of a saddle-type vehicle and is composed of an engine, a transmission, a clutch system, that enables switching between connection and disconnection of power transmission between a crankshaft and the transmission, and an electric motor capable of transmitting rotational power to the transmission. An operation of the electric motor alone is enabled with alleviation of the load. Thus, an increase in the size in the direction along the axis line of the crankshaft is avoided. The electric motor, rendered incapable of direct power transmission from and to a crankshaft, is housed in a transmission chamber so as to be allowed to transmit rotational power from a rotor of the electric motor to a transmission shaft. The rotor is disposed on an upper side relative to the highest oil level of lubricating oil in the transmission chamber.
