Abstract

An lubrication device for an engine includes: a crank case which freely rotatably supports a crank shaft and also which stores oil at its lower part; an oil strainer which is so arranged as to be fixed in the crank case; and an oil pump which suctions the oil at the lower part in the crank case via the oil strainer. In the lubricating device, the machining efficiency can be improved by reducing the time of machining to a crank case to thereby decentralize machining processes, and also the oil temperature can be reduced. A crank case cover covering part of a crank case and coupled with the crank case is provided with an oil suction passage which leads to an oil pump, and an oil strainer communicates with the oil suction passage via a connecting pipe which is a member different from the crank case.
