Abstract
A vertical internal combustion engine E is incorporated into an outboard motor or the like. The vertical internal combustion engine E includes a crankshaftenclosed in a crank chamber, and a belt-drive transmission mechanismincluding a rubber beltfor transmitting power of the crankshaftto a camshaft, and held in a belt chamber. The belt chamberis isolated from the crank chamberby a lower caseof a transmission caseholding the belt-drive transmission mechanismtherein such that the flow of an oil-containing gas from the crank chamberdeviates from a direction toward the belt. The beltis lubricated with oil injected concentratedly into the belt chamberthrough jet nozzlesdisposed in the belt chamber. Thus the excessive exposure of the beltto the oil-containing gas from the crank chamber can be avoided, the life of the belt can be extended and the belt is lubricated properly.
