- the air cleaner 17 air inlet 17 1 e and the Pelt chamber 2 3 1 chamber chamber air inlet 2 3 3 a are located above the engine 13 thermally insulated by the heat insulating member 401 relative to the vehicle body axis. It is disposed at a substantially symmetrical position. With such an arrangement, the air above the engine 13 is distributed to the left and right with respect to the vehicle body axis, and is uniformly taken into the air inlets 1 7 1 e and 2 3 3 a.
- the air taken in at the belt chamber intake port 2 3 3 a passes through the belt chamber intake duct 2 3 3 and is further cleaned by the belt chamber air cleaner 2 3 4 Is supplied.
- An element 2 3 4 a is provided in the belt chamber 2 3 1 air cleaner 2 3 4.
- the belt chamber intake port 2 33 3 a is formed of, for example, an elastic member such as rubber, and can cope with the vertical swing of the swing type drive pinion 11.
- the entire belt chamber suction duct 2 33 may be integrally formed of, eg, plastic.
- the air cleaner is disposed above the engine, and the bottom surface of the object storage portion on the lower side of the seat and the upper surface of the air cleaner are formed in substantially the same shape. In the upward swing of Even if there is, it approaches at a substantially constant interval. Therefore, by arranging the air cleaner above the engine, the vehicle body can be made slender, and the sheet height can be suppressed to secure the capacity of the object storage portion and the air cleaner.
- the air cleaner can be divided into the front and rear parts, and the rear part of the air cleaner is exposed below the lower edge of the cover. This makes it easy to replace the air cleaner. In addition, since the rear of the power unit is exposed, it is possible to make the car body thinner.
- the air cleaner is disposed above the engine, and the air cleaner intake port and the transmission device intake port are provided inside the cover above the engine and in front of the air cleaner. Since it is arranged in the space surrounded by the engine and the air cleaner, it is possible to make the vehicle body slender and to suppress the entry of dust into the engine and the inside of the transmission.
- the engine and the air cleaner are supported such that at least a portion is narrower than the distance between the pair of left and right frames and positioned between the frames when at least a part of the engine and the air cleaner swings. For this reason, it is possible to make the width direction and the front and back direction of the vehicle compact while suppressing the seat height.
- the intake duct of the transmission can be made simple, and the width direction and the front and rear direction of the vehicle can be made compact.
- the air cleaner intake port and the transmission apparatus intake port are separated in the left-right direction, interference between intakes from each other is suppressed. You can control.
- the air cleaner intake port and the transmission apparatus intake port are biased upward and downward, interference between the intake air of each other can be suppressed.
- the heat insulating member is disposed between the engine and the air cleaner such that the tip end is located closer to the front of the engine and the rear end extends rearward from the air cleaner and the air inlet of the transmission. Therefore, it is possible to suppress the intake of air warmed by the heat of the engine into the air cleaner, and to suppress the decrease in engine performance.
- the lower waterproof flap provided on the lower side of the air cleaner has its upper side bent to the rear wheel side and the lower side hangs down so as to cover the engine. Dust can be properly prevented from entering the air cleaner and engine.
- the upper waterproof flap installed on the upper side of the air cleaner curves when the power unit swings downward, so that the lower side contacts the upper side of the air cleaner and bends, so the dust from the rear wheel side becomes air cleaner and engine Properly prevented from entering the
- the lower waterproof flaps and the upper waterproof flaps are fixed to the vehicle body frame by a plurality of mounting projections formed to project from the both flaps. Therefore, by simply fitting the plurality of mounting projections into the mounting holes of the vehicle body frame, the two flaps can be fixed extremely easily, and work efficiency can be improved and economy can be achieved. Can.
