Like this; Through from suction port 78 to forming repeatedly crooked inlet air pathway the air filter element E; Especially stream to above the air inlet that changes import can capture ratio anharmonic ratio air big water of the rearward end on road 91 or sand etc.; The eyelet obstruction that can suppress them to arrive air filter element E and cause etc., and can keep the strainability of air filter element E for a long time well.In addition, the moisture that accumulates in the rearward end on air inlet importing road 91 etc. is discharged to outside the shell through said floss hole 79b.
Air inlet import road 91 on by suction port lower wall 86,87 and in the lead-in portion of outer side wall 85,88 encirclements; Along with Backwards and left and right sides narrowed width from suction port 78; Afterwards; Be bent the curved section that wall 96, outer side wall 84, stage casing wall 89 and lower wall 83 surround, keeping roughly certain sectional shape and extension rearward.That is, owing to outer side wall 84 is the amount that divider 95 is given prominence to left to the outstanding and outstanding amount of left also, therefore behind the said lead-in portion of process, the stream that air inlet imports road 91 does not narrow down.
In addition, because curved wall 96 and outer side wall 84 form to the outstanding arch in the shell outside, therefore utilize its shape can improve self rigidity and other reinforcer etc. need be set, and can realize reducing air inlet sound.And then; Because divider 95 is outstanding to left, its outer side wall 84 (curved wall 96) leaves from air filter element E, and the admission space in air filter element E dead ahead (right inner space 93) enlarges; Therefore can carry out air inlet effectively, can improve the output capability of motor 22.
That kind as described above; The air filter case 28 of two-wheeled 1 in the foregoing description is that the boundary is divided into the dirty side of suction port 78 sides and the clean side of motor 22 sides with the inner space of air-cleaner box 71 with the air filter element E that in this air-cleaner box 71, accommodates, keeps; Import road 91 through the air inlet that is arranged at divider 95 in the said air-cleaner box 71 and marks off said suction port 78 sides and import the right inner space 93 of the road 91 crooked said air filter element E sides that link to each other with respect to this air inlet in said dirty side; Said divider 95 has along the short flange 95a of the reference level K of flat condition in its periphery; This weak point flange 95a is combined, is bearing on the said air-cleaner box 71, and this divider 95 is to be configured in order to enlarge said right inner space 93 import the side-prominent member in road 91 with respect to said reference level K to said air inlet.
According to this structure; On the one hand the periphery of divider 95 is combined, is bearing on the air-cleaner box 71 along the reference level K of flat condition; Making this divider 95 import road 91 sides (an opposite side with air filter element E) with respect to said reference level K to air inlet on the one hand gives prominence to; Thus; On the basis of inheriting existing structure, can enlarge the air inlet stream (right inner space 93) in said air filter element E dead ahead, can not have to utilize whole air filter element E to come to carry out effectively air inlet biasedly.
In addition; In above-mentioned air filter case 28; What said air inlet imported road 91 is arranged to outstanding and outstanding to the outside of said air-cleaner box 71 (with said divider 95 opposite sides) corresponding to said divider 95 with said divider 95 relative wall portions (outer side wall 84); Divider 95 is formed to air inlet import the width that road 91 side-prominent outstanding shapes are guaranteed air inlet importing road 91; And make the outer side wall 84 of air-cleaner box 71 outstanding to the shell outside, and also can guarantee the width of right inner space 93, can further carry out air inlet effectively.
In addition, this invention is not limited to the foregoing description, and for example, air filter element also can be a member cylindraceous and that formed by urethane fat vacuole foam material, and in addition, the reference level of divider also can be slight curving or to have a small stair poor.And the structure of stream etc. self-evidently can be carried out various changes in the detail shape of air-cleaner box, divider, air-cleaner box in the scope that does not break away from main points of the present invention.
