To increase down force that is generated by receiving travel wind flowing from upper front to lower rear of a front part of an under cowl, and to suppress heat build-up in the under cowl.SOLUTION: An under cowl 6 comprises a right wall part 7, a left wall part 8 and a front wall part 9. The front wall part 9 comprises a first wind reception plate 11 and a second wind reception plate 12, and the first wind reception plate 11 and the second wind reception plate 12 have wind reception surfaces 11A, 12A respectively that receive travel wind from upper front to lower rear of the front wall part 9. Each wind reception surface 11A, 12A expands in the front, rear, left and right directions, and has a front edge part which is inclines down relative to a rear edge part. Further, the second wind reception plate 12 is located so that a front end part thereof becomes an upper side and a rear side with respect to a front end part of the first wind reception plate 11, and a gap 13 is provided between the first wind reception plate 11 and the second wind reception plate 12.SELECTED DRAWING: Figure 4

    【課題】アンダーカウルの前部の上前方から下後方に流れる走行風を受けることによって生成されるダウンフォースを増大させ、かつアンダーカウル内の熱の籠もりを抑制する。【解決手段】アンダーカウル6は、右壁部7、左壁部8および前壁部9を備え、前壁部9は第1の風受け板11および第2の風受け板12を備え、第1の風受け板11および第2の風受け板12はそれぞれ、前壁部9の上前方から下後方に流れる走行風を受ける風受け面11A、12Aを有し、各風受け面11A、12Aは、前後左右方向に拡がり、前縁部が後縁部に対して下がるように傾斜している。また、第2の風受け板12は、その前端部が第1の風受け板11の前端部よりも上側かつ後ろ側となるように配置され、第1の風受け板11と第2の風受け板12との間には間隙13が設けられている。【選択図】図4
