ABSTRACT:
In an OHV engine in which a pair of cylinder blocks is connected to the crankcase and power from a cam is transmitted to a rocker arm pivotably supported by the cylinder heads via connecting rods, to enable downsizing of the engine while reducing the number of components and the number of assembling steps. A part of the connecting rods out of the respective connecting rods are respectively stored in a rod storage chamber provided in both cylinder heads, both cylinder blocks and a crankcase between the cylinder axes of the adjacent cylinder bores in the respective cylinder blocks. The remaining connecting rod disposed outwardly of the cylinder axes of the outermost cylinder bores laid along the axis of the crankshaft is stored in part in a pipe member disposed at the position away from the outer walls of the cylinder blocks. In addition, the supporting shaft on the engine body is inserted into and supported by a plurality of shaft supporting members provided in the engine body and the arms are pivotably supported by the supporting shaft.
