Abstract

Straddle type vehicle takes traveling wind into a space between paired left and right main frames. Air is introduced to an air cleaner arranged between the paired left and right main frames. The paired main frames include left and right U-shaped portions having U-shaped cross sections opened inward in the vehicle width direction and constituting a part of an air cleaner case. Hollow left and right frame portions are provided below the left and right U-shaped portions, and the air cleaner is arranged between the left and right U-shaped portions.

First claim

The invention claimed is:

1. A straddle type vehicle, comprising:
a head pipe;
paired left and right main frames branching into left and right vehicle width directions from the head pipe and extending toward a vehicle rear; and
an opening provided in a vicinity of said head pipe configured to take in traveling wind to introduce air from the opening to an air cleaner disposed between said paired left and right main frames,
said paired left and right main frames including
left and right U-shaped portions having U-shaped cross sections opened inward in the vehicle width direction and constituting a part of an air cleaner case, and
hollow left and right frame portions provided below the left and right U-shaped portions,

wherein said air cleaner is disposed between said left and right U-shaped portions, and
wherein the left and right U-shaped portions at least partially overlap a portion of the hollow left and right frame portions.

2. A straddle type vehicle, comprising:
a head pipe;
paired left and right main frames branching into left and right vehicle width directions from the head pipe and extending toward a vehicle rear; and
an opening provided in a vicinity of said head pipe configured to take in traveling wind to introduce air from the opening to an air cleaner disposed between said paired left and right main frames,
said paired left and right main frames including
left and right U-shaped portions having U-shaped cross sections opened inward in the vehicle width direction and constituting a part of an air cleaner case, and
hollow left and right frame portions provided below the left and right U-shaped portions,

wherein said air cleaner is disposed between said left and right U-shaped portions, and
said left and right U-shaped portions comprising:
left and right ceiling portions extending inward in the vehicle width direction;
left and right wall portions extending downward from outer ends of the left and right ceiling portions; and
left and right floor portions extending inward in the vehicle width direction from bottom ends of the left and right wall portions,
wherein said air cleaner comprises a cleaner case cover,
said left and right ceiling portions include an attachment hole configured to attach said cleaner case cover from above, and wherein
said cleaner case cover is attached to said left and right ceiling portions by a fastening member inserted into said attachment hole.

3. The straddle type vehicle according to claim 2 , wherein:
said left and right floor portions are connected at a lower connecting portion, and the lower connecting portion together with said left and right floor portions form a connecting bottom portion,
a vehicle front end of the connecting bottom portion continues to a bottom portion of said opening,
a vehicle rear end of said connecting bottom portion continues to a rear end of said air cleaner,
front portions of said left and right ceiling portions are connected at an upper ceiling portion, and the upper ceiling portion together with said left and right ceiling portions form a connecting ceiling portion; and
wherein a vehicle front end of the connecting ceiling portion continues to a ceiling portion of said opening.

4. A straddle type vehicle, comprising:
paired left and right main frames branching into left and right vehicle width directions from a head pipe and extending toward a vehicle rear;
an engine provided below the paired left and right main frames; and
an air cleaner constituting an intake system of the engine provided between said paired left and right main frames,
said paired left and right main frames including
a plate-shaped connecting bottom portion bridged across the paired left and right main frames,
left and right outer wall portions extending upward and downward from the plate-shaped connecting bottom portion,
left and right ceiling portions extending inward in the vehicle width direction from top ends of said left and right outer wall portions, and
left and right inner wall portions extending downward from said plate-shaped connecting bottom portion inside said left and right outer wall portions in the vehicle width direction,

wherein said air cleaner includes an air cleaner case; and wherein
the air cleaner case is disposed above said plate-shaped connecting bottom portion.

5. The straddle type vehicle according to claim 3 , wherein a first hole portion is provided in said connecting bottom portion, and a funnel configured to take air into the engine is disposed so as to penetrate said first hole portion, wherein
one end of the funnel is connected to said engine, and wherein another end of said funnel is disposed inside said air cleaner.

6. The straddle type vehicle according to claim 2 , further comprising:
a convex portion provided in said left and right ceiling portions;
a concave portion to be fitted into said convex portion, provided in said cleaner case cover; and
an O ring provided between said convex portion and said concave portion.

7. A straddle type vehicle, comprising:
a head pipe;
paired left and right main frames branching into left and right vehicle width directions from the head pipe and extending toward a vehicle rear; and
an opening provided in a vicinity of said head pipe configured to take in traveling wind to introduce air from the opening to an air cleaner disposed between said paired left and right main frames,
said paired left and right main frames including
left and right U-shaped portions having U-shaped cross sections opened inward in the vehicle width direction and constituting a part of an air cleaner case, and
hollow left and right frame portions provided below the left and right U-shaped portions,

wherein said air cleaner is disposed between said left and right U-shaped portions,
said air cleaner includes a cleaner filter,
one end of said cleaner filter is locked onto a first locking portion formed in said paired left and right main frames, and
another end of said cleaner filter is locked onto a second locking portion formed in said cleaner case cover.

8. The straddle type vehicle according to claim 7 , wherein a second hole portion is provided in said connecting bottom portion at a position below said connecting ceiling portion and closer to a vehicle front than said cleaner filter, and wherein said second hole portion communicates into hollow portions of said frame portions.

9. The straddle type vehicle according to claim 4 , wherein said engine is supported by bottom ends of said left and right main frames and rear ends of said left and right main frames, the bottom ends of said left and right main frames support said engine through a first fastening bolt extending in the vehicle width direction, and wherein the rear ends of said left and right main frames support said engine through a second fastening bolt extending parallel to an axial direction of said head pipe.

10. A straddle type vehicle, comprising:
head pipe means for supporting vehicle steering components thereupon;
left and right main frame means branching into left and right vehicle width directions from the head pipe means, and extending toward a vehicle rear; and
opening means provided in a vicinity of the head pipe means, said opening means for taking in travelling wind and introducing air from the opening means to an air cleaner means disposed between the left and right main frame means,
said left and right main frame means including
left and right U-shaped means having U-shaped cross sections opened inward in the vehicle width direction, said U-shaped means for forming part of an air cleaner case means, and
hollow left and right frame means disposed below the left and right U-shap
