To provide a noise reduction structure capable of reducing the noise generating at the time of on-vehicle battery cooling without disturbing air inflow from an air-supply opening.SOLUTION: A noise reduction structure comprises: a cooling fan for cooling an on-vehicle battery; a duct in which the air taken in by the cooling fan for cooling a vehicle room circulates; a cover body connected to the duct to cover the in-vehicle air-supply opening being an inflow port of the cooling air; and a reduction louver provided on a circulation route of the cooling air. In the reduction louver, a plurality of louver bodies having a C-shaped cross sectional face are arranged in parallel, and C-shaped notch parts are arranged toward the inside of the circulation route of the cooling air.SELECTED DRAWING: Figure 1
【課題】給気用開口からの空気流入を妨げることなく、車載電池の冷却時に生起する騒音を低減させることが可能な騒音低減構造を提供する。【解決手段】車載電池の冷却を行う冷却用ファンと、冷却用ファンにより取り込まれる車室内の冷却用空気が流通するダクトと、ダクトに連結され、冷却用空気の流入口となる車室内の給気用開口を覆うカバー体と、冷却用空気の流通経路上に設けられた低減ルーバーと、を備えると共に、低減ルーバーは、断面C字形状とした羽体を複数平行且つC字形状の切欠部を冷却用空気の流通経路内側へ向け配置したことにより課題を解決した。【選択図】図1
