    Abstract: An upper structure of an engine in which secondary air is supplied to an exhaust port of an engine (20). The upper structure includes: a cylinder head (23) in which an exhaust camshaft (56) and an intake camshaft (57) are installed; a cylinder head cover (24) fixed on the cylinder head by fastening members (69a to 69c); a reed valve (73) configured to prevent backflow of exhaust gas from the exhaust port to an upstream side; and an ignition plug (59) positioned between the intake camshaft and the exhaust camshaft. An accommodating portion (74) for accommodating the reed valve is provided adjacent to the ignition plug above the exhaust camshaft in the cylinder head cover. A supply path (64) for introducing secondary air from the accommodating portion to the exhaust port is formed on an opposite side of the cylinder head cover from the ignition plug across the exhaust camshaft.
