向に通る中心線に沿って後方へ飛散するため、後輪に多
くの雨水が当たる。このため後輪の路面グリップ力が減
少するという不都合があった。(Background of the Invention) In a motorcycle, the front steering wheel throws up rainwater when traveling in the rain. Since the rainwater thrown up scatters rearward along the center line passing through the vehicle body in the front-rear direction, a large amount of rainwater hits the rear wheels. Therefore, there is a disadvantage that the road grip force of the rear wheels is reduced.

ズの状態で安定してバンクできる。44 is a substantially flat plate-shaped footrest located below the steering bar handle in the handlebar cover 30 and the driving seat 38, 46 is a rear cover that covers the power unit 18 and the upper side of the rear wheel 26, 48
Is a leg shield that covers the front portion of the steering shaft tube 12 and the front frame 14 from the front and back. In this embodiment, when the driver sits on the driver's seat 38 and places his feet on the footrest 44 with his feet aligned, the rear part near the lumbar vertebra of the driver is supported near the upper center of the backrest part 42 and near the lumbar vertebrae. The rear side portion of the back portion is supported near both sides of the upper portion of the backrest portion 42. Therefore, the driver's body is firmly held on the driver's seat 38, particularly from the waist to the back. If the body weight of the driver is leaned to the left or right, the body of the driver is restricted from moving to the left or right at the backrest portion 42, so that the vehicle body also leans in the same direction. That is, the body and the vehicle body are integrally banked to the left and right, and stable banking can be performed in a so-called lean with state.

止でき、安定して超低速で走行できる。At extremely low speeds, the driver can strengthen the integration of the body with the vehicle body by pressing the back or the vicinity of the waist against the backrest portion 42, so that it is possible to effectively prevent the vehicle body from wobbling and to stably maintain the extremely low speed. You can drive in.
なお背あて部42の上部は運転者の腰椎付近の後側方に当
接しているから、運転者の腰付近の保温が可能である。
特に寒さに敏感な腎臓付近の保温効果があるので、冬期
の走行が楽になる。Since the upper part of the backrest portion 42 is in contact with the rear side near the lumbar vertebra of the driver, it is possible to keep warm around the waist of the driver.
It helps keep you warm in the winter, especially in the cold sensitive kidneys.
この実施例では背あて部42の下部の幅を狭くしたので、
臀部の寸法が異なる運転者が着座する場合にも楽に着座
できると共に、走行抵抗が増えないという効果が得られ
る。In this embodiment, since the width of the lower portion of the backrest portion 42 is narrowed,
Even when a driver with different buttocks is seated, the seat can be easily seated and running resistance is not increased.
なおこの背あて部42は着脱式としてもよいのは勿論であ
る。Of course, the backrest portion 42 may be detachable.
足置台44は第３〜５図に示すように、運転者の足が載る
上板50と、その下方を覆うアンダカバー52とを備え、こ

れている。As shown in FIGS. 3 to 5, the footrest base 44 includes an upper plate 50 on which the driver's foot rests and an undercover 52 that covers the lower part of the upper plate 50. The upper plate 50 and the undercover 52 are fixed to the frame 10. ing.
従ってアンダカバー52は、前輪34後方の車体下面に位置
している。Therefore, the under cover 52 is located on the lower surface of the vehicle body behind the front wheels 34.

導水溝52B、52Bの間隔は車体後方へ向うに従って次第に
拡大し（第２図参照）、その後端は足置台44後部の左右
側下縁から車体後側方を指向している。The under cover 52 is formed with a central bulging portion 52A that projects downward substantially along a center line that passes through the vehicle body in the front-rear direction, and the left and right sides of the central bulging portion 52A have a cross section that is convex upward. The water guiding grooves 52B and 52B are formed so that The distance between the water guiding grooves 52B and 52B gradually increases toward the rear of the vehicle body (see FIG. 2), and the rear end thereof extends from the lower left and right edges of the rear portion of the footrest 44 toward the rear side of the vehicle body.

4後部の両側縁から車体外側方へ排出される。Therefore, the rainwater thrown up by the front wheels 34 when traveling in the rain hits the undercover 52, but is guided to the left and right water guiding grooves 52B by the central bulging portion 52A at the front part thereof and is sent to the rear of this water guiding groove 52B together with the traveling wind. . Since the water guiding groove 52B is deviated to the outer side of the vehicle body as it goes rearward, rainwater entering the water guiding groove 52B is also guided by the water guiding groove 52B and is deflected to the outer side of the vehicle body and flows backward. And finally the footrest 4 at the rear end of the water conduit 52B
4 It is discharged to the outside of the vehicle from both sides on the rear.
このように前輪34がまき上げる雨水は導水溝52Bによっ
て車体外側方へ導かれる。このため後輪26に当たる雨水
は減少する。In this way, the rainwater which the front wheels 34 roll up is guided to the outside of the vehicle body by the water guide groove 52B. Therefore, the amount of rainwater that hits the rear wheel 26 is reduced.

導水溝を形成すればよい。In the above embodiment, the undercover 52 is provided on the lower surface of the foot stand 44 of the scooter, and the central bulging portion 52A and the water guiding groove 52B are formed in the undercover 52. However, the present invention can also be applied to an undercover installed so as to cover the lower part of the engine in a normal motorcycle in which the driver puts his feet on both sides of the engine arranged behind the front wheels. Also includes things. In this case, the undercover is usually formed so that its cross section is convex downward, but it is sufficient to form a water guiding groove whose cross section is convex upward on the slopes on both sides of this convex central bulge.
また前記実施例では、左右一対の導水溝52B、52Bを設け
たが、複数対の導水溝を設けたものも本発明は包含す
る。Further, although the pair of left and right water guiding grooves 52B, 52B are provided in the above-described embodiment, the present invention also includes a plurality of water guiding grooves provided.

る。Since the undercover is usually formed with a smooth curved surface, its rigidity tends to decrease, but by applying the present invention, the rigidity can be increased and the function of protecting the lower part of the vehicle body from road surface obstacles and the like is improved. The effect of, is also obtained.

Since the gap between the two water guiding grooves is widened toward the rear of the vehicle body, the rainwater which the front wheels wind up is guided to the outside of the vehicle body by these water guiding grooves. As a result, the amount of rainwater that hits the rear wheels is reduced, and the road grip force of the rear wheels is increased.
