<p>In order to protect a fuel injection valve (17) from interference with foreign matter in an engine, in which a cylinder axis is directed substantially horizontal, an air cleaner (22) is mounted to a vehicle front side of a cylinder head (20) in an overlapping state. A fuel injection valve (17) is mounted to an upper surface of the cylinder head (20). An intake pipe (40) connects between the upper surface of the cylinder head (20) and an upper surface of the air cleaner (22). As viewed from laterally of a vehicle, the intake pipe (40) is laid to bypass above the fuel injection valve (17). Consequently, the fuel injection valve (17) is arranged inside a region surrounded by the cylinder head (20), the air cleaner (22), and the intake pipe (40), so that it is protected from interference with foreign matters.
