[Object] In a hybrid power unit that 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, operation of the electric motor alone is enabled with alleviation of the load and increase in the size in the direction along the axis line of the crankshaft is also avoided. [Solving Means] An electric motor MA rendered incapable of direct power transmission from and to a crankshaft 13 is housed in a transmission chamber 24 in such a manner as to be allowed to transmit rotational power from a rotor 46A of the electric motor MA to a transmission shaft 34, and the rotor 46A is disposed on the upper side relative to the highest oil level of lubricating oil in the transmission chamber 24. |
