P In the air intake of conventional vehicles, to prevent water from seeping into the air filter housing

In the V body, the waterproof rib is set on the rear fender facing the inlet of the intake duct of the air cleaner case (see, for example, Patent Document 1). <Patent Document 1 &gt; Japanese Patent No. 3 3 0 8 3 4 0

(Problems to be Solved by the Invention) However, the above-described conventional construction is limited in the range of the waterproof rib. Further, there is a problem that the gap between the rear fender and the air cleaner case is increased or decreased, which affects the drainage of water along the rear fender.

Accordingly, the present invention provides an air intake device for a vehicle that can cover the outer circumference of the intake duct in a wide range, improve water repellency, and maintain a gap between the rear fender and the air cleaner housing to improve drainage. (Means for Solving the Problem) As a solution to the above problem, the invention of claim 1 is characterized in that it is provided in a suction air cleaner case (for example, the air cleaner case 5 1 of the embodiment). An intake duct of the intake air (for example, the intake duct 53 of the embodiment) is disposed on the side of the cover of the air cleaner case (for example, the cover 6 1 of the embodiment), and integrally covers the outer circumference of the intake duct. A catheter cap (such as the catheter cap 1 1 2 of the embodiment) is attached to the cap. 5 312XP/Invention Manual (Supplement)/94-09/941 ] 7209 1306489 According to this configuration, a large range around the intake duct can be covered by the duct cover. Further, the duct cover and the casing cover can be integrally operated. The invention according to claim 2 is characterized in that the duct cover has an opening portion penetrating the intake duct (for example, the duct through opening portion 1 16 of the embodiment), and the mounting portion of the casing cover of the intake duct (For example, the catheter fitting groove portion 108 of the embodiment) supports the opening portion. According to this configuration, the opening portion of the intake duct and the mounting portion of the duct cover can be shared, and the mounting structure can be simplified.

According to this configuration, the mounting configuration can be simplified as compared with the case where the catheter cover is attached to the cover using a fastener or the like. Further, it is possible to effectively prevent the floating of the outer peripheral portion of the duct cover. At this time, if the invention of the fifth aspect of the patent application is made to lock the rear portion of the duct cover to the rear fender (for example, the rear fender 4 2 of the embodiment), the rear mud can be maintained. The gap between the plate and the catheter cover is fixed. The invention of claim 6 is characterized in that a rib portion (for example, a rib portion 1 2 4 of the embodiment) extending in the front-rear direction is provided on the rear surface of the rear fender facing the rear side of the duct cover. According to this configuration, it is ensured that the predetermined gap is between the rear of the duct cover and the rear fender. The invention of claim 7 is characterized in that the above-mentioned duct cover is composed of an elastic member. According to this configuration, even if it interferes with the bottom plate of the seat cushion or the like, it is easily deformed and can be excellently absorbed. (Effect of the Invention) According to the invention of claim 1, the water repellency of the air cleaner case can be improved by widely covering the periphery of the intake duct. Further, the assembly and removal work of the duct cover and the casing cover can be easily performed, and the number of work can be reduced.

According to the invention as set forth in claim 2, the attachment structure of the intake duct and the casing cover can be simplified, and the cost of the air cleaner casing can be reduced. According to the invention of the third and fourth aspects of the patent application, the installation structure of the duct cover can be simplified, and the cost of the air cleaner case can be reduced. Further, it is possible to prevent the outer peripheral portion of the duct cover from floating, and to properly maintain the waterproofness and commerciality of the air cleaner case. According to the invention contained in items 5 and 6 of the patent application, the gap between the rear mud plate and the pipe cover can be ensured, and the drainage of water transferred to the rear fender can be improved.

According to the invention as set forth in claim 7, the assembly and removal work of the duct cover, the seat cushion, and the like can be easily performed, and the number of the work can be reduced.
