  "textContent": "An exhaust emission control device for an internal combustion engine includes multiple reed valve chambers (7) which include reed valves (7a), and which are provided on cylinder head portions (40L, 40R) of a multi-cylinder internal combustion engine (4). The reed valve chambers are formed by covering recessed portions (40a) in the cylinder head portion with reed valve covers (71). Upstream sides (7A) of the reed valve chambers communicate with the atmosphere via a secondary air supply pipe (72), and downstream sides (7B) communicate with exhaust ports (37) via communication passages (91) in the cylinder head portion. The multiple reed valve covers communicate individually with and are formed integrally with the secondary air supply pipe, and the reed valve covers are connected in series by the secondary air supply pipe. The size and weight of the exhaust emission control device can be reduced.",
