Abstract: A piston with transverse-rib through holes formed easily therein for reducing the cost of manufacturing. A piston includes a pair of mutually opposed longitudinal ribs individually formed with piston pin bosses interconnecting a pair of piston skirt portions on a back side of a piston head. A pair of transverse ribs interconnect the mutually opposed longitudinal ribs with the transverse ribs. The pair of transverse ribs are formed with transverse-rib through holes at places proximal to the back side of the piston head. A skirt opening is formed by cutting away a part of the piston skirt portion that is opposed to the transverse rib and faces the transverse-rib through hole.

Abstract: A hybrid vehicle includes an engine; a motor; a power transmission mechanism and an oil pump for lubricating the engine and the power transmission mechanism with the rotation of a crankshaft. The oil pump has an oil pump shaft with an oil pump driven gear on one end thereof through a one-way clutch and an oil pump driven sprocket on the other end of the oil pump shaft through a one-way clutch. The oil pump driven gear is connected to a primary drive gear rotating integrally with a motor driven gear for transmitting the power of the motor to the drive wheel. The oil pump driven sprocket is connected to a cam chain of the engine to be rotated by power of the engine. The motor driven gear is disposed on one side of the crankshaft and the cam chain is disposed on the other side of the crankshaft.
