AI Technical Summary
In saddle-riding vehicles, the air guiding port of the shroud allows a significant amount of running air to enter the area below the fuel tank, while also needing to prevent water infiltration, such as raindrops, which requires separating the air cleaner's intake port from the air guide path and providing a wall to prevent water entry.
The saddle-ride type vehicle incorporates a wind guide member behind the head pipe with an air guide port that opens towards the front, equipped with a downwardly inclined louver to reduce water intrusion while maintaining airflow efficiency.
This configuration effectively suppresses water intrusion into the air guide port while ensuring efficient airflow to the air intake port, improving the rectifying effect and waterproofing of the air guide opening.

Abstract
Description
[Technical field]
[0001] The present invention relates to a saddle-ride type vehicle. [Background technology]
[0002] Conventionally, in saddle-type vehicles, a tank shroud (shroud: an air guide member that covers vehicle parts and guides airflow in a specific direction) is extended toward the front of the vehicle from the side of the fuel tank located at the driver's knee grip position, and an inner member of this shroud is positioned behind the head pipe of the body frame, and this inner member has an air guide port that is provided below the fuel tank (see, for example, Patent Document 1). [Prior art documents] [Patent documents]
[0003] [Patent Document 1] JP 2013-075585 A Summary of the Invention [Problem to be solved by the invention]
[0004] It is desirable for the air intake of the shroud to be configured to take in a large amount of wind generated while traveling into the area below the fuel tank, while suppressing the intrusion of water such as raindrops. For example, in a shroud intended to draw air into the air cleaner below the fuel tank, in order to prevent water from infiltrating through the air intake, it was necessary to position the air cleaner intake away from the air intake path or to provide a wall in front of the intake to prevent water from infiltrating.
[0005] SUMMARY OF THE PRESENT DISCLOSURE In view of the above, an object of the present invention is to prevent water from entering through an air guide port in a saddle-ride type vehicle having an air guide member behind the head pipe that takes in airflow produced while the vehicle is running. [Means for solving the problem]
[0006] As a means for solving the above problem, a first aspect of the present invention is characterized in that in a saddle-type vehicle (1) including a head pipe (6) and an air guide member (45) arranged rearward of the head pipe (6), the air guide member (45) is provided with an air guide port (51) that opens toward the front of the vehicle, and the air guide port (51) is provided with a louver (52) that is inclined downwardly and forward. According to this configuration, by providing the air guide member behind the head pipe with an air guide port that opens to the front of the vehicle, the traveling wind that reaches the air guide port first hits the head pipe and the steering parts supported by the head pipe, causing the wind speed to drop, and the louvers of the air guide port make it easier to straighten the air flow. Furthermore, by providing the air guide port with a louver that is inclined downward, it is possible to prevent the intrusion of water contained in the traveling wind without impeding the flow of the traveling wind to the rear of the air guide member.
[0007] A second aspect of the present invention is characterized in that, in the above-mentioned first aspect, it comprises an internal combustion engine (13) and an air cleaner (21) connected to an intake side of the internal combustion engine (13), an air intake port (22a) of the air cleaner (21) is arranged rearward of the air guide member (45), and the air intake port (22a) is arranged so as to at least partially overlap with the air guide port (51) in the vehicle width direction. According to this configuration, the intake port of the internal combustion engine and the air guide port of the air guide member are arranged so as to overlap in the vehicle width direction, which makes it easier to introduce the wind generated by driving from the air guide port to the intake port, thereby improving the intake efficiency.
[0008] A third aspect of the present invention is characterized in that, in the above-mentioned first or second aspect, a pair of left and right front forks (3) are supported on the head pipe (6) so as to be steerable, and the air guide port (51) is positioned rearward and inward in the vehicle width direction relative to the pair of left and right front forks (3). According to this configuration, by locating the air guide port rearward and inward in the vehicle width direction relative to the left and right front forks, the traveling wind reaching the air guide port first hits the left and right front forks and is reduced in speed, making it easier to straighten the air with the louvers and to prevent water from entering. In other words, the straightening effect and waterproofing effect of the air guide port can be improved.
[0009] A fourth aspect of the present invention is characterized in that, in any one of the first to third aspects, the air guide member (45) has a concave portion (49) that is recessed toward the rear of the vehicle in a top view, and the air guide port (51) is formed from a rear end position (49a) of the concave portion (49) toward the inside in the vehicle width direction in a top view. According to this configuration, the air guide opening is formed in the range from the rear end position of the concave portion that is concave toward the rear of the vehicle in a top view of the air guide member toward the vehicle width direction (the range of the concave portion in the vehicle width direction) toward the inside, so that the range on the outside of the concave portion in the vehicle width direction can be used as an air guide, and more traveling air can be guided to the air guide opening. The traveling air guided on the outside of the concave portion in the vehicle width direction changes its flow direction and its wind speed is reduced, so that it is easy to straighten the air by the louver and to prevent water from entering. In other words, the straightening effect and waterproof effect of the air guide opening can be improved.
[0010] A fifth aspect of the present invention is characterized in that, in the above-mentioned second aspect, it further comprises a radiator (23) arranged in front of the internal combustion engine (13) and used to cool the internal combustion engine (13), and a radiator shroud (40) attached to the radiator (23), the radiator shroud (40) comprising an outer shroud (41) on the outer side in the vehicle width direction and an inner shroud (45) on the inner side in the vehicle width direction, and the air guide port (51) is formed in the inner shroud (45). According to this configuration, the air guide port is formed in the inner shroud of the radiator shroud that covers the radiator, which makes it easier to introduce the running wind to the rear of the radiator shroud, and therefore the running wind can be efficiently guided to vehicle parts such as an air cleaner disposed behind the radiator shroud.
[0011] A sixth aspect of the present invention is characterized in that, in the second aspect, there is provided a fuel tank (18) arranged above the internal combustion engine (13) and storing fuel for the internal combustion engine (13), and a tank shroud (30) attached to the fuel tank (18), and the air guide port (51) is at least partially overlapped with the tank shroud (30) in a side view of the vehicle. According to this configuration, the tank shroud that covers the fuel tank and the air guide port overlap each other when viewed from the side of the vehicle, making the air guide port less noticeable when viewed from the side of the vehicle and reducing the impact on the appearance. In addition, the tank shroud can be used to guide more running wind to the air guide port.
[0012] A seventh aspect of the present invention is characterized in that, in any one of the first to sixth aspects, the air guide port (51) at least partially overlaps with an area (5c) surrounded by frame members (6, 7, 7a) of the vehicle body frame (5). According to this configuration, the air guide port and the area surrounded by the frame member of the body frame face each other, so that the airflow generated during traveling can be efficiently guided to the area surrounded by the body frame behind the air guide member. Effect of the Invention
[0013] According to the present invention, in a saddle-ride type vehicle having an air guide port for taking in airflow generated while the vehicle is running in an air guide member behind the head pipe, it is possible to prevent water from entering through the air guide port.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0015] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the following description, the directions of front, rear, left and right are the same as those in the vehicle described below unless otherwise specified. In addition, in the drawings used in the following description, an arrow FR indicating the front of the vehicle, an arrow LH indicating the left side of the vehicle, an arrow UP indicating the top of the vehicle, and a line CL indicating the center of the left and right of the vehicle body are shown at appropriate positions.
[0016] <Entire vehicle> As shown in Fig. 1, this embodiment is applied to a motorcycle 1 as an example of a saddle-ride type vehicle. A front wheel (steerable wheel) 2 of the motorcycle 1 is supported at the lower end of a pair of left and right front forks 3. Upper portions of the left and right front forks 3 are steerably supported on a head pipe 6 at the front end of a body frame 5 via a steering stem 4. A bar-type steering handle 4a is attached to a top bridge 4b of the steering stem 4. In the figure, reference numeral 4c denotes a bottom bridge of the steering stem 4, and reference numerals 4d and 4e denote a meter device and a headlight device supported by the steering stem 4, respectively.
[0017] The body frame 5 includes a head pipe 6, a pair of left and right main frames 7 extending downward and rearward from an upper portion of the head pipe 6, a pair of left and right gusset pipes 7a extending between a lower portion of the head pipe 6 and front portions of the left and right main frames 7, and a pair of left and right down frames 7b extending downward and rearward from the left and right gusset pipes 7a. The configuration including the head pipe 6 and the left and right frame members in its vicinity (the front upper portions of the left and right main frames 7 and the left and right down frames 7b, and the left and right gusset pipes 7a) is referred to as the frame front end portion 5a.
[0018] A power unit PU including a prime mover of the motorcycle 1 is supported below the left and right main frames 7. The power unit PU integrally includes an engine (internal combustion engine, prime mover) 13 located in front of it and a transmission (not shown) located in the rear. For example, the engine 13 is an air-cooled single-cylinder engine with the rotation axis of the crankshaft aligned in the left-right direction (vehicle width direction). A fuel tank 18 that stores fuel for the engine 13 is supported above the left and right main frames 7.
[0019] Although not shown, the body frame 5 includes a pivot frame connected below the rear ends of the left and right main frames 7, and a seat frame connected to the rear of the left and right main frames 7 and the pivot frame. A front end of a swing arm is supported on the pivot frame so as to be able to swing up and down. A rear wheel (drive wheel) of the motorcycle 1 is supported on the rear end of the swing arm. The rear wheel is connected to an output portion of the power unit PU (output portion of the transmission) via, for example, a chain-type transmission mechanism.
[0020] The fuel tank 18 includes a hollow tank body 19. The tank body 19 is made of, for example, a steel plate, and has concave knee-grip portions 19a formed on both the left and right sides of the rear portion so as to fit along the knees of the driver. 5, the inside of the front part of the tank body 19 in the vehicle width direction is formed in a concave shape that opens downward, and an air cleaner 21 that filters the intake air of the engine 13 is arranged in this concave shape. A pair of left and right intake ducts 22 extend from a case of the air cleaner 21 toward the front side of the vehicle, and the front end openings of these left and right intake ducts 22 serve as intake ports 22a of the air cleaner 21. The intake ports 22a are arranged in an area between the left and right frame members (inter-left frame area 5b). Traveling wind can be introduced into the inter-left frame area 5b from an air guide port 51, which will be described in detail later, and outside air that is not subjected to heat from the engine 13 or the radiator 23 can be supplied to the engine 13.
[0021] As shown in Figs. 1 to 4, tank shrouds 30 are attached to both the left and right sides of the front part of the tank main body 19 so as to cover these parts from the outside on the left and right. 1 and 2, the tank shroud 30 is formed to protrude outward to the left and right in front of the knee grip portion 19a. The front end 19b of the tank main body 19 is formed to be rounded so that the left and right width becomes narrower toward the front, whereas the front portion 30a of the tank shroud 30 is formed to be wider in left and right width than the tank main body 19 toward the front. The front portion 30a of the tank shroud 30 has a triangular shape that protrudes toward the front of the vehicle in a side view of the vehicle, extends forward beyond the front end 19b of the tank main body 19, and a lower edge portion 30c side of the front portion 30a overlaps with the front portion of the main frame 7. In the drawings, the reference symbol 30d indicates an upper edge portion of the front portion 30a of the tank shroud 30. The front end portion 30b of the tank shroud 30 extends to a position overlapping the head pipe 6 in a side view of the vehicle. The tank shroud 30 functions as a wind guide member that receives a large amount of wind from the front of the vehicle and guides it in a specific direction, thereby reducing the amount of wind that strikes the driver's knees.
[0022] 4, the tank shroud 30 includes a pair of left and right tank outer shrouds 31 arranged on the outer side in the vehicle width direction, and a tank inner shroud 35 arranged on the inner side in the vehicle width direction. The left and right tank outer shrouds 31 form the shape of the tank shroud 30 in a side view. The tank inner shroud 35 is integrally provided across between the upper edge portions of the front parts of the left and right tank outer shrouds 31 (corresponding to the upper edge portion 30d of the front part 30a of the tank shroud 30), and covers the front end portion 19b of the tank main body 19 from the front. The tank inner shroud 35 has an upwardly convex curved shape so as to straddle above the front part of the main frame 7 in a front view of the vehicle.
[0023] The left and right side portions of the tank inner shroud 35 are formed with upper concave portions 36 that are recessed in an arc shape toward the rear of the vehicle in a top view. The upper concave portions 36 are provided so as to be continuous with a lower concave portion 49 of the radiator inner shroud 45, which will be described in detail later. The upper and lower concave portions 36, 49 are formed in a concave shape so as to avoid the rotation area of the left and right front forks 3 when the front wheel 2 is turned (see FIG. 5). The upper and lower concave portions 36, 49 are inclined so as to be positioned further forward as they are lower, so as to follow the inclination of the left and right front forks 3 (and the head pipe 6) in a side view of the vehicle.
[0024] 1 to 3, a radiator 23 for cooling the engine 13 is disposed in front of the engine 13 and in front of the down frame 7b. The radiator 23 has a rectangular thick plate shape in a front view of the vehicle. The radiator 23 is disposed with upper and lower side portions 23a, 23b aligned along the left-right direction in a front view of the vehicle, and is disposed at an incline so that the lower side is positioned further rearward in a side view of the vehicle. The radiator 23 has a left-right width that exceeds the distance between the front ends of the left and right tank outer shrouds 31 (corresponding to the front end portions 30b of the tank shroud 30), and the left and right ends of the upper side portion 23b are disposed below the front end portions 30b of the left and right tank outer shrouds 31.
[0025] A radiator shroud 40 is attached to the left and right side edge portions 23c of the radiator 23 so as to cover the portions from the outside in the vehicle width direction. The radiator shroud 40 is formed so as to protrude outward in the vehicle width direction at the upper portion except for the vicinity of the lower end portion of the left and right side edge portions 23c. The radiator shroud 40 protrudes outward in the vehicle width direction beyond the front end portions 30b of the left and right tank outer shrouds 31. The radiator shroud 40 extends above the upper edge portion 23a of the radiator 23. The radiator outer shroud 41 on the outer side of the radiator shroud 40 in the vehicle width direction extends rearward in a portion (outer upper portion 41) located above the radiator 23, and the upper portion of this extending portion overlaps the lower edge portion 30c of the front portion 30a of the tank shroud 30 from the outside in the vehicle width direction.
[0026] The radiator shroud 40 is formed so that its front side is open toward the front of the vehicle, similar to the tank shroud 30. The radiator shroud 40 receives a large amount of wind from the front of the vehicle and guides it to the radiator 23, and also functions as a wind guide member that guides a portion of the wind toward the inter-frame region 5b.
[0027] 1 to 4, the radiator shroud 40 includes a pair of left and right radiator outer shrouds 41 arranged on the outer side in the vehicle width direction, and a pair of left and right radiator inner shrouds 45 arranged on the inner side in the vehicle width direction. The left and right radiator outer shrouds 41 form the shape of the radiator shroud 40 in a side view, except for an upward extension portion 47 of the radiator inner shroud 45, which will be described later. The left and right radiator inner shrouds 45 are provided between front portions of the left and right radiator outer shrouds 41, and are separated in the left-right direction across the frame front end portion 5a.
[0028] The radiator 23 is located in front of and below the frame front end 5a. The left and right radiator inner shrouds 45 are provided in a region below the tank inner shroud 35 and above the radiator 23, and close the spaces on both the left and right sides of the frame front end 5a. On the outer sides of the left and right radiator inner shrouds 45 in the vehicle width direction, downward extensions 48 are formed that extend downward along the left and right side edges 23c of the radiator 23, and close the spaces between the left and right radiator outer shrouds 41 and the left and right side edges 23c of the radiator 23.
[0029] The left and right radiator inner shrouds 45 include an inner main body portion 46 arranged on the outer side in the vehicle width direction of the lower structure of the frame front end portion 5a (upper front portions of the left and right down frames 7b and the left and right gusset pipes 7a), and an upward extension portion 47 extending above the inner main body portion 46 and inward in the vehicle width direction and arranged on the outer side in the vehicle width direction of the upper portion of the head pipe 6. The upward extension portion 47 extends above the upper edge portions 41b of the left and right radiator outer shrouds 41. The upward extension portion 47 extends above the front end portion 30b of the tank outer shroud 31.
[0030] The upper end of the upward extension portion 47 protrudes above the upper side portion 30d of the front portion 30a of the tank outer shroud 31, but most of the upward extension portion 47 is disposed on the inner side in the vehicle width direction of the front portion 30a of the tank outer shroud 31. For this reason, the upward extension portion 47 is difficult to see when viewed from the side of the vehicle.
[0031] The range from the upper edge of the inner main body 46 to the outer edge and upper edge of the upward extension 47 is joined to the range from the lower edge to the inner edge of the tank inner shroud 35. The range from the inner edge of the inner main body 46 to the lower edge of the upward extension 47 is appropriately cut out to avoid the lower structure of the frame front end 5a. In the embodiment, the right inner main body 46 and the upper extension 47 are further cut out to avoid not only the lower structure of the frame front end 5a but also rope-like members such as a clutch cable and a brake hose. For this reason, the cutout shapes of the inner main body 46 and the upward extension 47 are asymmetrical.
[0032] 1 to 4, the upward extension 47 is formed with an air guide port 51 for introducing traveling wind into the region 5b between the left and right frames. The air guide port 51 is disposed to face frame openings 5c (see FIG. 1) on both the left and right sides of the frame front end 5a. The frame openings 5c are triangular regions surrounded by the head pipe 6, the main frame 7, and the gusset pipes 7a on each of the left and right sides of the frame front end 5a. The traveling wind that reaches the air guide port 51 is introduced into the region 5b between the left and right frames through the air guide port 51 and the frame openings 5c.
[0033] The air guide port 51 is disposed on the inside in the vehicle width direction of the front portion 30a of the tank outer shroud 31, and like the upward extension portion 47, is difficult to see when viewed from the side of the vehicle. Therefore, the influence on the appearance caused by providing the upward extension portion 47 and the air guide port 51 is suppressed. On the other hand, the air guide port 51 disposed at the front of the vehicle body makes the intake sound more audible to the rider than when the air guide port 51 is disposed at the middle portion between the front and rear of the vehicle body or at the rear. This improves the marketability of the motorcycle 1.
[0034] In the radiator shroud 40, which receives a large amount of the traveling wind, the air guide port 51 opening toward the front of the vehicle is configured to be able to introduce a large amount of the traveling wind into the region 5b between the left and right frames while suppressing the intrusion of water such as raindrops. 6, the air guide port 51 has a louver 52 inclined downward. The louver 52 has a plurality of blades 53 inclined so as to be positioned downward toward the front. When the wind passes through slit-shaped openings 54 between the blades 53 of the louver 52, rainwater, etc. contained in the wind hits the downwardly inclined blades 53 and is captured, and drips below the air guide port 51. This prevents rainwater, etc. from entering the region 5b between the left and right frames, and allows the wind to be well guided to the region 5b between the left and right frames.
[0035] Therefore, even in a configuration in which the intake port 22a of the air cleaner 21 faces the region 5b between the left and right frames, it is possible to prevent water from entering without impairing the intake efficiency. Also, it is not necessary to provide a waterproof structure on the intake duct 22 side of the vehicle parts such as the air cleaner 21, and the design freedom of the vehicle parts can be increased.
[0036] 4, the air guide opening 51 is offset upward with respect to the air intake opening 22a in a front view of the vehicle, and is disposed so as not to overlap with the air intake opening 22a (avoiding the air intake opening 22a). Therefore, the traveling wind introduced from the air guide opening 51 into the region 5b between the left and right frames is not introduced directly into the air intake opening 22a, and the intrusion of rainwater, etc. is further suppressed.
[0037] Referring to Figures 4 and 5, when viewed from above the vehicle, the air guide port 51 overlaps with the air intake port 22a in the vehicle width direction, and the air introduced into the area 5b between the left and right frames from the air guide port 51 is weakened by the vertical offset of the air guide port 51 and the air intake port 22a, and is then quickly introduced into the air intake port 22a.
[0038] A lower concave portion 49 that is recessed in an arc shape toward the rear of the vehicle when viewed from above is formed in the upward extension portion 47 of the radiator inner shroud 45. The lower concave portion 49 is provided so as to be continuous with the upper concave portion 36 (see FIG. 4) of the tank inner shroud 35, and together with the upper concave portion 36, avoids the rotation area of the left and right front forks 3.
[0039] The rear end position 49a of the lower concave portion 49 is located behind the front fork 3, and overlaps the front fork 3 in the vehicle width direction. The air guide opening 51 is formed in the range from the vicinity of the rear end position 49a of the lower concave portion 49 to the inside in the vehicle width direction. The traveling wind that reaches the lower concave portion 49 flows rearward while hitting the parts in front of it, such as the front fork 3, and the wind speed is appropriately reduced. After that, the traveling wind that reaches the inside of the lower concave portion 49 in the vehicle width direction is introduced into the region 5b between the left and right frames through the air guide opening 51. The traveling wind that reaches the outside of the lower concave portion 49 in the vehicle width direction changes direction toward the inside in the vehicle width direction along the curved shape of the lower concave portion 49 and reaches the air guide opening 51. This further reduces the wind speed of the traveling wind passing through the air guide opening 51, making it easier to straighten the louver 52 and to prevent water from entering.
[0040] As described above, the motorcycle 1 in the above embodiment is a saddle-ride type vehicle equipped with a head pipe 6 of a body frame 5 and an air guide member (radiator inner shroud 45) arranged behind the head pipe 6, and the radiator inner shroud 45 is equipped with an air guide port 51 that opens toward the front of the vehicle, and the air guide port 51 is equipped with louvers 52 (vanes 53) that are inclined toward the downward front. According to this configuration, by providing the radiator inner shroud 45 behind the head pipe 6 with the air guide port 51 that opens to the front of the vehicle, the traveling wind that reaches the air guide port 51 first hits the head pipe 6 and the steering parts supported by the head pipe 6, thereby reducing the wind speed, and the air flow can be easily rectified by the louvers 52 of the air guide port 51. Furthermore, by providing the air guide port 51 with the louvers 52 that are inclined downward, the intrusion of water contained in the traveling wind can be suppressed without impeding the flow of the traveling wind to the rear of the radiator inner shroud 45.
[0041] The motorcycle 1 is equipped with an engine 13 and an air cleaner 21 connected to the intake side of the engine 13. An intake port 22a of an intake duct 22 connected to the air cleaner 21 is disposed rearward of the radiator inner shroud 45. The intake port 22a opens toward the front of the vehicle rearward of the radiator inner shroud 45 and is disposed so as to overlap at least a portion of the air guide port 51 in the vehicle width direction. According to this configuration, the intake port 22a of the engine 13 and the air guide port 51 of the radiator inner shroud 45 are positioned so as to overlap in the vehicle width direction, making it easier to introduce the wind generated by driving from the air guide port 51 to the intake port 22a, thereby improving the intake efficiency.
[0042] The motorcycle 1 includes a pair of left and right front forks 3 steerably supported by the head pipe 6, and the air guide port 51 is disposed rearward and inward in the vehicle width direction of the pair of left and right front forks 3. According to this configuration, the air guide port 51 is disposed rearward and inward in the vehicle width direction relative to the left and right front forks 3, so that the traveling wind reaching the air guide port 51 first hits the left and right front forks 3 and is reduced in wind speed, making it easier to straighten the air by the louvers 52 and to prevent water from entering. In other words, the straightening effect and waterproof effect of the air guide port 51 can be improved.
[0043] In the above motorcycle 1, the radiator inner shroud 45 has a lower concave portion 49 that is recessed toward the rear of the vehicle in a top view, and the air guide port 51 is formed from a rear end position 49a of the lower concave portion 49 to the inside in the vehicle width direction in a top view. According to this configuration, the air guide port 51 is formed in a range from the rear end position 49a of the lower concave portion 49, which is concave toward the rear of the vehicle in a top view of the radiator inner shroud 45, to the inside in the vehicle width direction (the range of the inside of the concave shape in the vehicle width direction), so that the outside range of the lower concave portion 49 in the vehicle width direction can be used as an air guide, and more traveling wind can be guided to the air guide port 51. The traveling wind guided on the outside of the lower concave portion 49 in the vehicle width direction changes its flow direction and its wind speed is reduced, so that it is easy to straighten the flow by the louvers 52 and to prevent water from entering. That is, the straightening effect and waterproof effect of the air guide port 51 can be improved.
[0044] The motorcycle 1 is provided with a radiator 23 that is disposed in front of the engine 13 and is used to cool the engine 13, and the radiator inner shroud 45 is an inner shroud on the inside in the vehicle width direction of a radiator shroud 40 that is attached to the radiator 23. According to this configuration, the air guide port 51 is formed in the inner shroud of the radiator shroud 40 that covers the radiator 23, which makes it easier to introduce the running wind to the rear of the radiator shroud 40. Therefore, the running wind can be efficiently guided to the vehicle parts such as the air cleaner 21 arranged behind the radiator shroud 40.
[0045] The motorcycle 1 is provided with a fuel tank 18 disposed above the engine 13 for storing fuel for the engine 13, and a tank shroud 30 attached to the fuel tank 18, and the air outlet 51 is at least partially overlapped with the tank shroud 30 when viewed from the side of the vehicle. According to this configuration, the tank shroud 30 covering the fuel tank 18 and the air guide port 51 overlap each other when viewed from the side of the vehicle, making the air guide port 51 less noticeable when viewed from the side of the vehicle and reducing the impact on the appearance. In addition, the tank shroud 30 can be used to guide more traveling wind to the air guide port 51.
[0046] In the motorcycle 1, the air guide port 51 at least partially overlaps with a frame opening 5c surrounded by frame members of the body frame 5 (head pipe 6, main frame 7, and gusset pipe 7a). According to this configuration, the air guide port 51 and the frame opening 5c surrounded by the frame members of the body frame 5 face each other, so that the running wind can be efficiently guided to the left-right frame area 5b surrounded by the body frame 5 behind the radiator inner shroud 45.
[0047] The present invention is not limited to the above embodiment. For example, the present invention is not limited to the configuration in which the radiator inner shroud has the air guide port, and the radiator outer shroud or the tank shroud may have the air guide port. The air guide structure of the present embodiment may be applied to saddle-ride vehicles other than motorcycles. The saddle-ride vehicles include all vehicles on which the driver straddles the vehicle body, and include not only motorcycles (including motorized bicycles and scooter-type vehicles), but also three-wheeled vehicles (including vehicles with one front wheel and two rear wheels, as well as vehicles with two front wheels and one rear wheel) or four-wheeled vehicles (four-wheeled buggies, etc.). The present invention may also be applied to vehicles including an electric motor as a prime mover. The present invention is also applicable to vehicles other than saddle-ride vehicles (passenger cars, buses, trucks, etc.). The configurations in the above-described embodiments are merely examples of the present invention, and various modifications are possible without departing from the gist of the present invention, such as replacing the components of the embodiments with well-known components.
