Abstract
An oil pump includes an oil supply pump and an oil recovery pump disposed on an extension line of a crankshaft of an engine. One joint member is provided at an end portion of the crankshaft, and another joint member is provided at an end portion of a pump shaft. The two joint members are coupled to each other on the same axial line within a front cover of an engine. The two joint members have alternating concave portions and convex portions. The convex portions of the two joint members include inclined faces and opposing driving transmission faces. The inclined faces of the convex portions guide the convex portions into the concave portion of the opposing joint member, so that the two joint members are meshed with one another. The crankshaft side joint member is fastened together with an ACG rotor. An oil tank connected to the oil pump is disposed above and very close to the oil pump.
