To provide a wind-noise reduction structure of a side visor having a function of effectively reducing occurrence of wind noise caused by traveling air.SOLUTION: In a side visor 5, as rectifying means for rectifying flow of air flowing through an inner surface side of an eave body 8 is provided at least on the inner surface of the eave body in an inclined visor part 6, flow in a gap space 4 between the inner surface of the eave body 8 and a window glass 3 can be rectified (divided and fractionized) by the rectifying means. When the flow of air in the gap space 4 is rectified (divided and fractionized), flow of air closer to a downwind side than a rectifying member 10 is weakened so that occurrence of countercurrents can be reduced. When the countercurrents are reduced, collisions of the flow in the gap space 4 are reduced so that flow of air flown out to the outside is reduced. The reduction of the flow of air flown out to the outside can reduce occurrence of turbulence 19, so that wind noise can be effectively reduced more in comparison with a case where a rib at a lower edge of the side visor 5 is extended and a gap between a tip of the rib and the window glass 3 is narrowed.SELECTED DRAWING: Figure 1

    【課題】 走行風による風切音の発生を効果的に低減する機能を有するサイドバイザーの風切音低減構造を提供する。【解決手段】サイドバイザー5では、少なくとも傾斜バイザー部6における庇体8の内面に、この内面側を流れる空気の流れを整流する整流手段が備えられているので、整流手段によって庇体8内面と窓ガラス3との隙間空間4内の流れを整流(分裂、細分化)することができる。この隙間空間4内の流れが整流(分裂、細分化)されることにより、整流部材10より風下の流れが弱まり、対向流の発生を低減することができる。対向流が低減されることで隙間空間4内での流れの衝突は低減され、外側へ流出される流れが小さくなる。外側へ流出される流れが小さくなることで、乱流19の発生を小さくすることが可能となり、結果、サイドバイザー5下端縁のリブを延設し、リブの先端と窓ガラス3との隙間を狭くするだけの場合に比べ、風切音を効果的に低減することが可能となる。【選択図】図1
