Abstract
An oil-release space () is formed along a lower side portion () of a cylinder lateral and peripheral wall () below an oil-cooling jacket (). A reinforcing plate () spans between the lower side portion () of the cylinder lateral and peripheral wall () and a bottom wall () of a push-rod chamber () below the oil-release space (). The oil-release space () is communicated with an oil outlet () of an oil-return passage (). Engine oil that has passed through the oil-return passage () is released from the oil outlet () into the oil-release space (). The engine oil released into the oil-release space () is guided by an upper surface of the reinforcing plate () to drop from a led-out end () on a rear side of the reinforcing plate () onto a rear side space ().
