【Effect of the invention】
In the present invention, because the driver for driving variable valve actuating mechanism is arranged on the side wall of air filter, it is made
Side is covered by the lateral wall of air filter, and lower section is covered by power unit, it is thus possible to utilize power unit and air
Cleaner protects sidepiece and the bottom of driver, protects it from the collision influence of stone etc., in addition, make driver will not with it is attached
Near miscellaneous part produces interference, it is not necessary to set special protecting component in addition.
In addition, variable valve actuating mechanism has opening and switching valve, wherein, opening is formed in the extension of the air intake passage
Portion, and near the side wall configuration of the driver for installing the air filter, the switching valve is used to be opened and closed the opening,
Valve shaft is provided with the side wall of the air filter, the valve shaft is set through the side wall, and the switching valve is by the valve shaft
Supporting, the driver is connected to the end of the valve shaft.Thus, it is possible to switching valve and driver are made variable near configuration
Valve actuating mechanism miniaturization, compact conformation.
In addition, during side-looking, the upper and lower ends of the driver are located in the range of the height of air filter.Thus,
Driver can be completely covered from side by air filter, so that driver is protected solidly, and, it is to avoid
Driver is beyond the height direction of air filter, it is to avoid maximization.
In addition, the part outside air filter of air intake passage extends to internal combustion engine side, and relative to suction
The part extended inside air filter of gas passage leads to vehicle central lateral bend, driver configuration in the air-breathing by bending
In the lateral wall area defined of road and air filter.Thus, using air intake passage bend formed pipeline side with
The dead angle area that air filter lateral surface is surrounded carrys out configuration driven device, is not only able to protect driver, and can make knot
Structure densification.
Because power unit has the internal combustion engine, variable-speed motor and driving wheel, and the power unit is supported on the frame of vehicle
On frame, near the anterior configuration of variable-speed motor, and can be swung centered on swinging axle, air filter is arranged on power unit
On, and positioned at the rear of the swinging axle, for set driver air filter side wall to swinging axle.Thus, energy
Enough near pivot configuration driven device, in the less part configuration driven device of hunting range (pendulum angle) such that it is able to suppress to drive
Dynamic device in hunting range with it near part produce interference, minimize power unit.
Stretch out the support to be formed for supporting the swinging axle in the upper surface of the power unit, the supporting portion in
The front of the air filter, makes the swinging axle configuration in the front of the driver.Thus, it is possible to protected by pivot drive
Device is moved from coming from the influence of the flying below front.
The variable valve actuating mechanism has valve body, and valve body supports switching valve, the switching valve is rotated by valve shaft,
The sidepiece of valve body is formed with flange part, and valve body is arranged on the air filter by the flange part, the driving
Device is arranged on the flange part.Thus, it is possible to make that variable valve actuating mechanism is structure-integrated, simplicity, the quantity of part is reduced,
By variable valve actuating mechanism blocking, so as to be easily installed.
Reduction gearing is configured between the rotating shaft of the valve shaft and the driver, so that rotating shaft configuration is in institute
The top of valve shaft is stated, the jaw opening sensor of the aperture for detecting the switching valve is connected in the end of the valve shaft, it is described
Jaw opening sensor is configured in the lower section of the driver, and positioned at the top of the power unit.Thus, by valve shaft and driver
Rotating shaft be in staggered configuration, by driver configuration up, jaw opening sensor is connected to the end (axial end portion) of valve shaft, will open
Degree sensor configuration is between driver and power unit such that it is able to protect jaw opening sensor by the part of surrounding.

Variable valve actuating mechanism 106 is worked using inertia supercharging effect (inertia supercharging) of air-breathing.It is so-called
Inertia supercharging effect refers to that the inertia force of the air (air column (air column)) in the air intake passage of engine suction is formed
Pressurization.When slowly running, air intake passage is more long, and, in engine high-speed rotation, if air intake passage is shorter, meeting
Pressurization is produced, therefore, it is possible to rotating speed according to engine switches the length of air intake passage.I.e., in the present embodiment, exist
When engine speed is relatively low, switching valve 119 is closed, suck air via the connecting tube air entry 72c of connecting tube 72 so that air-breathing is led to
Road is more long.In addition, when engine speed is higher, opening switching valve 119, mainly inhaled via the connection tube opening 72d of connecting tube 72
Enter air so that air intake passage is shorter.In this way, air intake passage length is allowed hand over using variable valve actuating mechanism 106, so as to draw
