ー１３によりすつぽりと覆われている。 The embodiment shown in the figure shows a case where this invention is applied to a scooter type motorcycle, and the vehicle body includes a head pipe 2 that supports a front wheel 1 in a steerable manner.
The frame 4 between the frame 4 and the seat 3 is deeply curved downward in a U-shape as a whole, with a plate-shaped leg shield 5 extending to both sides attached to the front part, and a plate-shaped leg shield 5 extending to both sides at the bottom. A step board 6 is laid out below the seat 3, and the front end of a swing unit 9 on which an engine 7 and a blower 8 are mounted is pivoted to the frame 4 of the vehicle body by a shaft 10. It is suspended and supported by a frame 4 by a spring 11. The upper half of the swing unit 9 and rear wheel 12 are completely covered by a body cover 13.

ラジエータ１６がエア送風路１４のエアの流れ方
向に対し直角に取付けられている。 In the embodiment shown in the figure, a portion of the frame 4 extending from the horizontal lower part to the rear upper part is a hollow air blowing passage 14, and a duct cover 15 having a flared shape is connected to the rear end. A radiator 16 is attached to the rear end opening of the duct cover 15 at right angles to the air flow direction of the air blowing passage 14.

動きがダクト１８の伸縮方向にのみ作用するよう
に形成されている。 The duct 18 is arranged in a direction perpendicular to the center of swing of the swing unit 9, that is, a line connecting the shaft 10 and the air outlet 8a, and the duct 18 connects the air outlet 8a of the blower 8 and the air passage 14. This connection structure allows the swing unit 9 to move only in the direction of expansion and contraction of the duct 18.

できる。 Therefore, according to this invention, when an engine and a blower are mounted on a swing unit and a radiator is forced air-cooled from this blower through an air passage, the swing unit has elasticity in the direction perpendicular to the line connecting the fulcrum of the swing unit and the air outlet. By arranging a ventilation duct with a duct and connecting the ventilation opening of the blower and the ventilation opening provided on the vehicle body side with this ventilation duct, the vibration of the swing unit acts only in the direction of expansion and contraction of the duct. It is possible to significantly increase the durability of the swing unit without applying excessive force to the swing unit, and to make the movement of the swing unit smooth.

る場合にも適用可能である。 In addition, in the illustrated embodiment, an example is shown in which this invention is applied when a radiator is forcedly cooled by an air blower through an air passage in the frame, but it can also be applied even when the air passage is provided separately. Of course, it can also be applied to cases where the engine is directly forced air cooled.
