PROBLEM TO BE SOLVED: To reduce a travel resistance by enhancing an effect of straightening a travel wind while securing visibility of a tail light unit in a motor cycle in which a power unit is mounted on a vehicle body frame and the tail light unit for emitting light toward the rear side of a vehicle is arranged on a rear cowl covering a rear part of the vehicle body frame at least behind a riding seat.SOLUTION: Below a rear cowl 40 covering a rear part of a vehicle body frame F from the side and from above behind a riding seat, a straightening plate 50 is fixedly arranged, which covers the rear part of the vehicle body frame from below while allowing the air flowing rearward from the power unit to be straightened and exhausted to the vehicle rear side.SELECTED DRAWING: Figure 8

    【課題】パワーユニットが車体フレームに搭載され、乗車用シートの少なくとも後方で車体フレームの後部を覆うリヤカウルに、車両後方に向けて光を照射するテールライトユニットが配設される自動二輪車において、テールライトユニットの視認性を確保した上で、走行風の整流効果を高めて走行抵抗を減少する。【解決手段】乗車用シートの後方で車体フレームFの後部を側方および上方から覆うリヤカウル40の下方に、パワーユニットから後方に流れる空気を整流して車体後方に排出することを可能としつつ車体フレームFの後部を下方から覆う整流板50が固定配置される。【選択図】 図8
