Following explanation is carried out to the admission port of above-described inlet channel.
With reference to Fig. 4, inlet channel 47 extends out from airfilter 46 towards legging baffle plate 61.The admission port 103 of inlet channel 47 is at space 81 inner opening of legging baffle plate 61.The admission port 103 of inlet channel 47 is positioned at the outside of the side 114 on the right side of airfilter 46 on overall width direction, therefore, compared with being configured in the situation in the width range of the side 113,114 of the left and right of airfilter 46 with admission port 103, the admission port 103 of inlet channel 47 can be made away from the ear of chaufeur being positioned at overall width direction immediate vicinity.
Like this, because the admission port 103 of inlet channel 47 is away from the ear configurations of chaufeur being positioned at overall width direction immediate vicinity, therefore, it is possible to make air inlet sound be difficult to be transmitted to chaufeur.Because air inlet sound is difficult to be transmitted to chaufeur, therefore, it is possible to make the air inlet sound being transmitted to chaufeur reduce, and the complex structure of inlet channel 47 can not be made as in the past.Further, owing to can simplify the structure of inlet channel 47, therefore, intake air restriction also can reduce.
On this basis, owing to being attenuated, therefore, it is possible to make the air inlet sound being transmitted to chaufeur reduce further in space 81 in legging baffle plate of the air inlet sound dispersed from admission port 103.So, according to the present invention, can provide a kind of and can suppress the increase of intake air restriction and the two-wheeled vehicle 10 that air inlet sound can be made to reduce.
Simultaneously with reference to Fig. 1, Fig. 6 and Fig. 7, the crest line 150 of inner cover 63 is formed in the rear face of the legging baffle plate 61 of the rear view of vehicle side configuration of inlet channel 47, and extends towards the oblique back lower place of vehicle.Inlet channel 47 extends from airfilter 46 to the oblique back lower place of vehicle.The direction that formation legging baffle plate inner cover 63 below extends and the direction that inlet channel 47 extends are all towards the oblique back lower place of vehicle.
If when inlet channel 47 is to rear view of vehicle horizontal-extending, just needs to consider legging baffle plate 61 and the interference of inlet channel 47, just may produce restriction to the duct length of inlet channel 47.
This respect, in the present invention, become direction that legging baffle plate 61 inner cover 63 below extends and the direction that inlet channel 47 extends all towards the oblique back lower place of vehicle, therefore, the duct length of inlet channel 47 can be made to guarantee specified length, and can by legging baffle plate 61 miniaturization in vehicle lengthwise direction.
On this basis, because the admission port 103 of inlet channel is towards the oblique lower opening of vehicle, therefore, the direction of admission port 103 becomes towards direction, ground.Because the direction of admission port 103 is not towards chaufeur, therefore, it is possible to make the air inlet sound being transmitted to chaufeur reduce further.
Simultaneously with reference to Fig. 2, be formed with connected entrance 82 at the inner cover 63 of legging baffle plate 61.Owing to being provided with connected entrance 82, therefore, ambient atmos just enters into the space 81 in legging baffle plate 61.Therefore, it is possible to ambient atmos to be taken into very fully the space 81 in legging baffle plate 61.Further, connected entrance 82 is located at inner cover 63 bottom of legging baffle plate 61.Because inner cover 63 is towards rear view of vehicle, therefore, it is possible to the foreign matters such as the dust making the front-wheel 16 being positioned at legging baffle plate 61 front roll are difficult to enter into space from connected entrance 82.
With reference to Fig. 9 and Figure 10, arrange at the inner cover 63 of the rear face as legging baffle plate 61 and be arranged on different positions in the height direction from the position of the connected entrance 82 of ft connection and the admission port 103 of inlet channel 47.If when making the position of connected entrance and the position of admission port be arranged on cardinal principle same position in the height direction, the air inlet sound that admission port produces just is easy to be transmitted to chaufeur.
This respect, in the present invention, because connected entrance 82 is configured to than admission port 103 closer to below, therefore, it is possible to reduce the air inlet sound being transmitted to chaufeur.Further, because admission port 103 is set to than connected entrance 82 closer to top, therefore, it is possible to make the foreign matters such as the dust entered from connected entrance 82 be difficult to suck.
With reference to Fig. 5, inlet channel 47 between the first notch 107 being formed at shield 106 and the second notch 108 being formed at legging baffle plate 61 by and extend towards rear view of vehicle.
If when not arranging first notch 107 and second notch 108, after just needing outside the overall width direction making inlet channel 47 extend to shield 106, it is made to extend to rear view of vehicle.Therefore, the maximization on overall width direction may be caused.
This respect, in the present invention, at shield 106, the first notch 107 is set, at legging baffle plate 61, the second notch 108 is set, and through inlet channel 47 between these first notchs 107 and the second notch 108, therefore, it is possible to make inlet channel 47 at case of air cleaner 95(Fig. 4) side near pass, and can configure close on overall width direction to case of air cleaner 95 and legging baffle plate 61, seek the miniaturization on overall width direction.
Although illustrate example air filtering device structure being applied to two-wheeled vehicle in the present embodiment, also can be applied to three-wheel vehicle, be applied to common vehicle also passable.
