Cowl of saddle-ridden type vehicle
A cowl which covers a front component of a saddle-ridden type vehicle, includes: a cowl body; and passage forming portions each of which extends from a front, central, in a left-right direction, position of the cowl body or a vicinity of the front, central position to a side position of the cowl body; each of the passage forming portions forms an air passage that extends from the front, central position of the cowl body or a vicinity of the front, central position to the side position of the cowl body; the passage forming portions or each of the passage forming portions has an inlet as defined herein; each of the passage forming portions has an outlet as defined herein; and the air passages cause a riding wind occurring during running of the saddle-ridden type vehicle to flow through the air passages.
1. A cowl which covers a front component of a saddle-ridden type vehicle, comprising:
a cowl body; and
passage forming portions each of which extends from a front, central, in a left-right direction, position of the cowl body or a vicinity of the front, central position to a side position of the cowl body, wherein:
each of the passage forming portions forms an air passage that extends from the front, central position of the cowl body or a vicinity of the front, central position to the side position of the cowl body;
the passage forming portions or each of the passage forming portions has an inlet that is opened at the front, central position of the cowl body or a position near the front, central position so as to face the side in front of the cowl body;
each of the passage forming portions has an outlet that is opened at a side position of the cowl body so as to face the side on rear-left or rear-right of the cowl body; and
the air passages cause a riding wind occurring during running of the saddle-ridden type vehicle to flow through the air passages.
2. The cowl according to claim 1 , wherein the cowl body has curved portions each of which extends between a front portion or a front edge and a side end portion or side end of the cowl body while being curved so as to be convex outward and partially defines the associated air passage.
3. The cowl according to claim 1 , wherein the air passages are inclined with respect to a front-rear reference line, located at the center in the left-right direction, of the saddle-ridden type vehicle in an approximately horizontal sectional view.
4. The cowl according to claim 2 , wherein the air passages are inclined with respect to a front-rear reference line, located at the center in the left-right direction, of the saddle-ridden type vehicle in an approximately horizontal sectional view.
5. The cowl according to claim 1 , wherein:
the cowl body has, at the front, central position, a projection portion which projects forward;
the inlets are located near the projection portion; and
the cowl body has slant surfaces each of which extends from the projection portion to the inlet and is inclined gently so as to go rearward as the position goes from the projection portion to the inlet.
6. The cowl according to claim 2 , wherein:
the cowl body has, at the front, central position, a projection portion which projects forward;
the inlets are located near the projection portion; and
the cowl body has slant surfaces each of which extends from the projection portion to the inlet and is inclined gently so as to go rearward as the position goes from the projection portion to the inlet.
7. The cowl according to claim 3 , wherein:
the cowl body has, at the front, central position, a projection portion which projects forward;
the inlets are located near the projection portion; and
the cowl body has slant surfaces each of which extends from the projection portion to the inlet and is inclined gently so as to go rearward as the position goes from the projection portion to the inlet.
8. The cowl according to claim 4 , wherein:
the cowl body has, at the front, central position, a projection portion which projects forward;
the inlets are located near the projection portion; and
the cowl body has slant surfaces each of which extends from the projection portion to the inlet and is inclined gently so as to go rearward as the position goes from the projection portion to the inlet.
9. The cowl according to claim 1 , wherein the outlets are located higher than the inlets.
10. The cowl according to claim 2 , wherein the outlets are located higher than the inlets.
11. The cowl according to claim 3 , wherein the outlets are located higher than the inlets.
12. The cowl according to claim 4 , wherein the outlets are located higher than the inlets.
13. The cowl according to claim 1 , wherein each of the passage forming portions has a narrowing portion which makes the sectional area of the air passage smaller as the position goes from the inlet to the outlet.
14. The cowl according to claim 2 , wherein each of the passage forming portions has a narrowing portion which makes the sectional area of the air passage smaller as the position goes from the inlet to the outlet.
15. The cowl according to claim 3 , wherein each of the passage forming portions has a narrowing portion which makes the sectional area of the air passage smaller as the position goes from the inlet to the outlet.
16. The cowl according to claim 4 , wherein each of the passage forming portions has a narrowing portion which makes the sectional area of the air passage smaller as the position goes from the inlet to the outlet.
17. The cowl according to claim 1 , wherein each of the passage forming portions has a hole which causes an intermediate portion of the air passage to communicate with the inside of the cowl body.
18. The cowl according to claim 2 , wherein each of the passage forming portions has a hole which causes an intermediate portion of the air passage to communicate with the inside of the cowl body.
19. The cowl according to claim 3 , wherein each of the passage forming portions has a hole which causes an intermediate portion of the air passage to communicate with the inside of the cowl body.
20. The cowl according to claim 4 , wherein each of the passage forming portions has a hole which causes an intermediate portion of the air passage to communicate with the inside of the cowl body.
