Abstract: An electric supercharger-equipped moving machine includes: an engine; a supercharger configured to increase intake pressure of the engine; an electric motor including a motor driving shaft; a power transmitting path including a power transmitting shaft through which driving power of the engine is transmitted to a propulsive power generating body; and a switching clutch configured to be able to block power transmission from the electric motor to the power transmitting shaft. The motor driving shaft is connected to the supercharger so as to be able to drive the supercharger when the switching clutch is in a disengaged state. The motor driving shaft is connected to the power transmitting shaft so as to be able to drive the propulsive power generating body when the switching clutch is in an engaged state.

Abstract: An oil feed structure includes: a hydraulic clutch; a power transmitting shaft coupled to the hydraulic clutch; a valve element inserted into the power transmitting shaft, and a spring configured to bias the valve element. The valve element includes: a pressure receiving surface facing in an axial direction of the power transmitting shaft and configured to receive hydraulic pressure of a hydraulic pressure oil passage; and a port communicable with a clutch lubrication hole of the power transmitting shaft. The spring biases the valve element toward the hydraulic pressure oil passage against the hydraulic pressure received by the pressure receiving surface. When clutch operating hydraulic pressure changes, the valve element moves in the axial direction to change an opening degree of communication between the port and the clutch lubrication hole.

Abstract: A hybrid vehicle includes: a crankcase extending from a lower portion of a cylinder of an engine, the crankcase including a main body portion defining a crank chamber in which a crankshaft of the engine is accommodated, the crankcase further including a breather portion projecting upwardly from the main body portion and defining a breather chamber into which blowby gas is introduced from the crank chamber; a breather tube that introduces the blowby gas from the breather chamber into the intake passage; and a drive motor disposed rearwardly of the cylinder and mounted on a top surface of the crankcase. The breather portion has a facing surface facing an outer peripheral surface of the drive motor. The facing surface of the breather portion is shaped to conform to the outer peripheral surface of the drive motor.

Abstract: A crankcase includes: a main body portion aligned with a drive motor in a direction perpendicular to a motor drive shaft; and an extended portion continuous with the main body portion and located lateral to a motor housing, the extended portion receiving insertion of one end of the motor drive shaft. A power transmission mechanism that transmits power from the motor drive shaft to an input shaft is located partly in a first region defined by the main body portion and partly in a second region defined by the extended portion and communicating with the first region.
