A noise reduction device for an automotive vehicle (14), comprises an under-cover (10) fixedly disposed directly under an engine (12) supported by a vehicle body (14a), each under-cover (10) including a plurality of louver boards (24) each of which is inclined downwardly in the direction toward a vehicle front (F), thereby making engine noise harmless while improving heat-release of the engine. |
