To improve cooling efficiency by enhancing heat radiation performance of a rectifier.SOLUTION: A rectifier 50 is arranged so as to expose a heat radiation fin 54 in a front lower part of a main rear fender 42 provided above a rear wheel 12 in a position lower than the uppermost part of the rear wheel 12 in front of the rotation center of the rear wheel 12 of a motorcycle 10 in a normal travel state. An inner fender 45 is provided in the front lower part of the main rear fender 42 so as to cover a front upper part of the rear wheel 12, and the inner fender 45 extends backward more than a line of connecting the rear part lower edge of the heat radiation fin 54 and the rotation center of the rear wheel 12.SELECTED DRAWING: Figure 2

    【課題】レクチファイヤの放熱性能を高め、冷却効率を向上させる。【解決手段】通常走行状態の自動二輪車10の後輪12の回転中心よりも前方且つ後輪12の最上部より低い位置において、後輪12の上方に設けられる主リヤフェンダ42の前部下方に放熱フィン54が露出するようにレクチファイヤ50が配置されていることを特徴とする。主リヤフェンダ42の前部下方には、後輪12の前部上方を覆うようにインナーフェンダ45が設けられ、インナーフェンダ45は放熱フィン54の後部下縁と後輪12の回転中心とを結ぶ線よりも後方に延びている。【選択図】図2
