Abstract
Description
Technical Field
[0001] This invention relates to a straddle-type vehicle. Background Technology
[0002] In the past, in straddle-type vehicles, in order to make the side cover under the seat appear smaller, there was a structure that divided the side cover in front and behind (for example, see Japanese Patent No. 4721280). Summary of the Invention
[0003] In the aforementioned body cover structure, there is a desire to make the rear of the side cover appear smaller and lighter, and also to make the front side cover appear smaller.
[0004] On the other hand, in recent years, more and more people are conducting extensive research and development to contribute to energy efficiency in order to ensure a reliable and sustainable use of energy.
[0005] In the case of vehicles, in addition to improving the efficiency of the drive source, technologies that help improve aerodynamics are also effective.
[0006] Therefore, in the structure of the body cover as described above, it is desirable to also consider structures that improve aerodynamics.
[0007] The purpose of this invention is to improve the appearance and aerodynamics of a motorcycle with a segment exposed on the outer surface of the body cover.
[0008] The first aspect of the present invention is a motorcycle-type vehicle, comprising: a rear side cover covering the side of the rear part of the vehicle body; and a front side cover covering the side of the front part of the vehicle body. The rear side cover is divided into a first rear cover and a second rear cover by a rear dividing line extending from the front to the rear as viewed from the side of the vehicle. The front side cover is divided into a first front cover and a second front cover by a front dividing line extending from the front to the rear as viewed from the side of the vehicle. As viewed from the side of the vehicle, an imaginary extension of the rear dividing line passes above the upper end of the rear wheel. As viewed from the side of the vehicle, the imaginary extension of the front dividing line overlaps with one of the first rear cover and the second rear cover. An opening facing outwards in the vehicle width direction is formed at the portion of one of the first rear cover and the second rear cover that overlaps with the imaginary extension of the front dividing line as viewed from the side of the vehicle.
[0009] According to this structure, the rear and front side fairings each have a sloping rear and front dividing line that is higher at the front and lower at the rear (i.e., lower at the rear and higher at the front), thus creating a dynamic design when viewed from the side. The sloping rear dividing line, positioned slightly above the top of the rear wheels, flattens the slope (approaching horizontal) when viewed from the side, resulting in a speed-oriented appearance. An opening is formed at the point where one of the first and second fairings overlaps with the front dividing line, thus guiding the airflow along the front dividing line towards the periphery of the opening in the rear side fairing, achieving airflow straightening along the opening.
[0010] The second aspect of the present invention, based on the first aspect described above, may also be that the opening is formed at the upper edge of the opening that extends from the front to the rear when viewed from the side of the vehicle, and that the upper edge of the opening, the rear dividing line, and the front dividing line are substantially parallel to each other when viewed from the side of the vehicle.
[0011] According to this structure, the upper edge of the opening is substantially parallel to the dividing lines of the front and rear side covers, thus enabling a lightweight design with continuity.
[0012] The third embodiment of the present invention, based on the first embodiment described above, may also include an opening portion having an upper edge extending from the front to the rear when viewed from the side of the vehicle, a second upper edge extending from the front end of the upper edge extending from the front to the rear, a lower edge extending from the rear end of the upper edge extending from the front to the rear, and a second lower edge extending from the front end of the lower edge extending from the rear. When viewed from the side of the vehicle, the straight line connecting the front and rear ends of the opening portion is longer than the straight line connecting the upper and lower ends.
[0013] Based on this structure, the opening is made into a rhombus that is longer front to back when viewed from the side of the vehicle, thus creating a design that conveys a sense of speed.
[0014] The fourth aspect of the present invention, based on the third aspect described above, may also include a rear first cover or a rear second cover having the opening, which extends in a front-high-rear-low configuration when viewed from the side of the vehicle, a second upper cover extending from the front end of the upper cover in a front-low-rear-high configuration, a lower cover extending from the rear end of the upper cover in a front-low-rear-high configuration, and a second lower cover extending from the front end of the lower cover in a front-high-rear-low configuration.
[0015] Based on this structure, the first or second cover with the opening is diamond-shaped when viewed from the side of the vehicle, just like the opening, thus creating a design that conveys a sense of speed together with the opening. The first or second cover has a frame-like appearance, which evokes a sense of light airflow.
[0016] The fifth aspect of the present invention, based on the fourth aspect described above, may also include a footrest for passengers between the front body equipped with the front side cover and the rear body equipped with the rear side cover, and a bottom side cover facing downwards on the left and right outer sides of the footrest, wherein the bottom side cover is connected from below to the first rear cover or the second rear cover having the opening.
[0017] According to this structure, the bottom side covers on the left and right outer sides of the bottom pedal are connected from below to the first or second cover with an opening, thereby integrating the frame-shaped cover with the bottom side cover to achieve rationalization.
[0018] The sixth embodiment of the present invention, based on the fifth embodiment described above, may also be that the bottom side cover faces outward in the vehicle width direction.
[0019] According to this structure, when viewed from the side of the vehicle, the frame-shaped cover and the bottom cover can form a unified appearance.
[0020] The seventh aspect of the present invention, based on any of the first to sixth aspects described above, may also include fastening connections for fixing the first rear cover or the second rear cover having the opening to the vehicle body, located in front of, behind, and below the opening.
[0021] Based on this structure, the frame-shaped cover can be securely fastened and fixed in a balanced manner.
[0022] The eighth aspect of the present invention, based on the seventh aspect described above, may also include the arrangement of the opening in the area where the plurality of fastening connections are connected when viewed from the side of the vehicle.
[0023] According to this structure, multiple fastening connections are provided in a manner that surrounds the opening, thereby enabling the cover with the opening to be fastened and fixed in a balanced and good manner, and improving the appearance.
[0024] The ninth embodiment of the present invention, based on any of the first to sixth embodiments described above, may also be that the angle of inclination of the rear dividing line and the front dividing line relative to the horizontal line is within 45 degrees when viewed from the side of the vehicle.
[0025] Based on this structure, compared to cases where the rear and front dividing lines have large angles of inclination relative to the horizontal line, it can create an appearance that conveys a sense of speed.
[0026] The tenth aspect of the present invention, based on any of the first to sixth aspects described above, may also be that the line connecting the two ends of the rear dividing line is used as the rear dividing reference line, and the extended portion of the rear dividing reference line is used as the imaginary extended portion.
[0027] According to this structure, even if the dividing line is bent when viewed from the side of the vehicle, the configuration of the imaginary extension based on the dividing line can be appropriately determined.
[0028] According to the present invention, in a straddle-type vehicle where the segment is exposed on the outer surface of the body cover, improvements in appearance and aerodynamics can be achieved. Attached Figure Description

[0033] Figure 5 This is the front view of the aforementioned motorized two-wheeled vehicle. Detailed Implementation
[0034] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the directions (front, back, left, right, etc.) in the following description are the same as the directions in the vehicle described below. Furthermore, arrows indicating the front of the vehicle (FR) and the top of the vehicle (UP) are shown in appropriate positions in the drawings used in the following description.
[0035] Figure 1 This diagram shows a left-side view of a small motorcycle-type motorized two-wheeled vehicle (horse-riding type) 1, as an example of a vehicle, viewed from the left-right direction (vehicle width direction). The motorized two-wheeled vehicle 1 has a front wheel 3 as a steering wheel and a rear wheel 4 as a drive wheel. The front wheel 3 is supported by a front fork 3a and can be steered via handlebars 2. The rear wheel 4 is supported by a swing-type power unit 8 and can be driven by the power unit 8. A steering system component including the handlebars 2, front fork 3a, and front wheel 3 is steerably supported on the head tube 10a at the front end of the frame 10. The front part of the power unit 8 is sway-mounted and supported at the front-rear center of the frame 10 (not limited to the center). The power unit 8 includes a drive source 8a for vehicle movement and a transmission device 8b that transmits the driving force generated by the drive source 8a to the rear wheel 4. The drive source 8a may include, for example, at least one of an internal combustion engine and an electric motor.
[0036] A footrest 6 for the rider is located between the front wheel 3 and the rear wheel 4. A front body 11 is located in front of the footrest 6. A rear body 12 is located behind the footrest 6. The space K1 between the front body 11 and the rear body 12, and above the footrest 6, serves as the rider's straddle space. A handlebar 2 is positioned above the front body 11 and is covered by a handlebar cover 2a. A seat 5 for the rider is positioned above the rear body 12. A tiltable side rack 7 is located on the lower left side of the footrest 6, capable of supporting the motorcycle in an upright position tilted to the left.
[0037] The frame 10 of the motorized two-wheeled vehicle 1 is covered by a body cover 20. The body cover 20 has a front central cover 21 that covers the front body 11 from the front, front side covers 22 (front side covers) that cover the front body 11 from the left and right sides, and an inner cover 23 that covers the front body 11 from the rear.
[0038] In addition, the body cover 20 has a bottom cover 24 that covers the bottom step 6 from above, and a bottom side cover 25 that covers the bottom step 6 from the left and right sides.
[0039] In addition, the body cover 20 has a rear central cover 26 that covers the rear body 12 from the front, and rear side covers 27 (rear side covers) that cover the rear body 12 from the left and right sides.
[0040] The front center cover 21 and the front side cover 22 form the outer surface of the front body 11. The rear center cover 26 and the rear side cover 27 form the outer surface of the rear body 12. The upper surface of the bottom cover 24 forms the footrest 24a of the bottom step 6. The footrest 24a is, for example, flat across the entire width in the vehicle width direction. The bottom step 6 may also have a central passage that rises upwards from the inside in the vehicle width direction.
[0041] The rear cover 27 is divided into a lower rear cover 27a (rear first cover) and an upper rear cover 27b (rear second cover) by a rear dividing line 27c (rear dividing line) that slopes from front to back when viewed from the side of the vehicle.
[0042] Refer to together Figure 2 , Figure 3 The rear first cover 27a and the rear second cover 27b, for example, form a continuous outer surface that is in the same plane. It should be noted that the rear cover 27 is not limited to a structure where the rear first cover 27a and the rear second cover 27b form a single outer surface. For example, the rear first cover 27a and the rear second cover 27b can also be a so-called layered cowl structure, where one is offset relative to the other in the vehicle width direction and they overlap. In this case, the end edge of the cover on the outer side in the vehicle width direction can be used as the rear dividing line 27c.
[0043] Reference Figure 1The rear dividing line 27c of the rear side cover 27 is straight when viewed from the side of the vehicle. This straight line along the rear dividing line 27c is used as the rear dividing reference line 27d (rear dividing reference line). If the rear dividing line 27c is curved when viewed from the side of the vehicle, the straight line connecting the front and rear ends of the rear dividing line 27c is used as the rear dividing reference line 27d when viewed from the side of the vehicle. The range defining the front and rear ends of the rear dividing line 27c may exclude, for example, portions that are locally tilted in the opposite direction near the front and rear ends of the rear dividing line 27c.
[0044] In this implementation, a line that extends continuously for more than half the length of the entire dividing line is used as the dividing line. Lines with different orientations that become part of a reverse slope near the front and rear ends are not included.
[0045] The rearward extension (imaginary extension) of the rear segment reference line 27d, when viewed from the side of the vehicle, passes above the upper end t1 of the rear wheel 4 (and does not overlap with the rear wheel 4 when viewed from the side of the vehicle). The angle θ1 of the direction in which the rear segment reference line 27d slopes from the horizontal line (front-high, rear-low, or rear-low, front-high) when viewed from the side of the vehicle (the angle of slope from the horizontal line) is within 45 degrees. Thus, the rear segment reference line 27d and the rear segment line 27c suppress the angle of slope from the horizontal line when viewed from the side of the vehicle, thereby achieving a horizontal tone and contributing to a speed-like appearance. The rear segment reference line 27d and the rear segment line 27c slope from the front-high, rear-low when viewed from the side of the vehicle, thereby contributing to a dynamic appearance. The rear side of the rear segment reference line 27d is located at an upper position, thereby enabling the miniaturization of the rear second cover 27b. The rear first cover 27a becomes large, but on the other hand, it has an opening 31, thus appearing smaller than it actually is, resulting in a nimble appearance.
[0046] A rhomboid opening 31 is formed in the rear first cover 27a when viewed from the side of the vehicle. The opening 31 has an upper edge 31a that extends from the front to the rear when viewed from the side of the vehicle, a second upper edge 31b that extends from the front end of the upper edge 31a that extends from the front end to the rear end, a lower edge 31c that extends from the rear end of the upper edge 31a that extends from the front end to the rear end, and a second lower edge 31d that extends from the front end of the lower edge 31c that extends from the front end to the rear end. The front end of the second lower edge 31d is connected to the front end of the second upper edge 31b. When viewed from the side of the vehicle, the angle formed by the second lower edge 31d and the second upper edge 31b is an acute angle, and the angle formed by the lower edge 31c and the upper edge 31a is also an acute angle.
[0047] Reference Figure 2When viewed from the side of the vehicle, the straight line L2 connecting the front and rear ends t4 and t5 of the opening 31 is longer than the straight line L1 connecting the upper and lower ends t2 and t3. That is, the shape of the opening 31 when viewed from the side of the vehicle is a rhombus with a front-to-back width greater than its top-to-bottom width.
[0048] Each end edge 31a-31d of the opening 31 appears as a straight line when viewed from the side of the vehicle. Specifically, the straight line along the upper end edge 31a of the opening is used as the reference line 31a1 for the upper end edge of the opening (see reference). Figure 1 When the upper edge 31a of the opening is bent under the side view of the vehicle, the straight line connecting the front and rear ends of the upper edge 31a of the opening under the side view of the vehicle will be used as the upper edge reference line 31a1.
[0049] The opening 31 extends through the rear first cover 27a in the vehicle width direction, for example. A split cover 33 can be installed inside the opening 31 to close it. This prevents vehicle components inside the rear first cover 27a in the vehicle width direction from protruding outwards from the opening 31. By forming the opening 31, the rear first cover 27a can appear smaller and lighter, contributing to improved aesthetics.
[0050] The rear first cover 27a has a rhomboid shape, which, when viewed from the side of the vehicle, is approximately similar to the opening 31. The rear first cover 27a has an upper edge 32a extending from the front (higher at the front, lower at the rear) when viewed from the side of the vehicle; a second upper edge 32b extending from the front end of the upper edge 32a (lower at the front, higher at the rear); a lower edge 32c extending from the rear end of the upper edge 32a (lower at the front, higher at the rear); and a second lower edge 32d extending from a portion or the front of the lower edge 32c (higher at the front, lower at the rear). The front end of the second lower edge 32d connects to the front end of the second upper edge 32b. When viewed from the side of the vehicle, the angle between the second lower edge 32d and the second upper edge 32b is an acute angle, and the angle between the lower edge 32c and the upper edge 32a is also an acute angle. That is, the shape of the rear first cover 27a is also a rhomboid whose front-to-back width is larger than its top-to-bottom width. The first cover 27a has an appearance like a frame with diamond-shaped openings, which is a design that evokes the flow of light air.
[0051] The upper edge 32b and lower edge 32d of the second cover of the rear first cover 27a are formed by ridges substantially parallel to the upper edge 31b and lower edge 31d of the second opening of the opening 31. An upper inclined surface 32b1 extending inward in the vehicle width direction is formed on the inner side of the upper edge 32b of the second cover. A lower inclined surface 32d1 extending inward in the vehicle width direction is formed on the inner side of the lower edge 32d of the second cover. The front ends of the upper and lower inclined surfaces 32b1 and 32d1 are connected to each other in front of the rhomboid front end (top) of the rear first cover 27a. The upper and lower inclined surfaces 32b1 and 32d1 are arranged in front of the opening 31 in an acute V-shape that protrudes forward when viewed from the side of the vehicle.
[0052] The rear end of the bottom cover 25 is integrally connected to the lower end of the first rear cover 27a.
[0053] The outer surface 25a of the bottom side cover 25 faces outward and downward in the vehicle width direction. The bottom side cover 25 has an extension 25c extending obliquely rearward and above the rear end of the outer surface 25a, via a ridge 25b substantially parallel to the footrest 24a. The upper end of the extension 25c connects from below to the lower end (the lower end (top) of the rhomboid shape) of the rear first cover 27a. The rear first cover 27a and the bottom side cover 25 are integrally formed, for example, by one-piece molding.
[0054] Reference Figure 2 The rear first cover 27a and the bottom side cover 25 are integrally fixed to the vehicle body by multiple fastening connections. These fastening connections include a first fastening connection 34a located in front of the opening 31, a second fastening connection 34b located behind the opening 31, and a third fastening connection 34c located below the opening 31. Each fastening connection 34a, 34b, and 34c is shaped to expose large screws outwards in the vehicle width direction, forming a mechanical design that complements the frame-like appearance of the rear first cover 27a. When viewed from the side of the vehicle, the opening 31 is generally positioned in the area R1 connecting the centers of each fastening connection 34a, 34b, and 34c, allowing the frame-like rear first cover 27a to be securely fastened in a balanced and well-proportioned manner.
[0055] The bottom cover 25 on the left side of the vehicle body is secured to the lower frame (not shown) by claws 25d at two locations on the upper edge. Although not shown, the bottom cover 25 on the right side of the vehicle body is secured to the lower frame by claws at two locations on both the upper and lower edges.
[0056] The lower part of the bottom cover 25 on the left side of the vehicle body is cut out to ensure the configuration space of the side parking rack 7, and the claws (locking parts) on the two parts of the lower edge are removed compared with the bottom cover 25 on the right side of the vehicle body.
[0057] Reference Figures 2-4 The lower side cover 25 on the left side of the vehicle body has a protrusion 25e that protrudes outward in the vehicle width direction from the lower edge of the cutout for the side parking rack 7. The protrusion 25e is, for example, fin-shaped (plate-shaped) and elongated in the vehicle longitudinal direction, which helps to straighten the airflow around the side parking rack 7. The protrusion 25e protrudes outward in the vehicle width direction from the outer surface of the lower side cover 25. The protrusion 25e is only provided on the left side of the vehicle body and also functions as an overhang extending upward around the root periphery of the side parking rack 7.
[0058] Reference Figure 1 , Figure 5 The front fairing 22 is divided into an upper front first fairing 22a (front first fairing) and a lower front second fairing 22b (front second fairing) by a front dividing line 22c (front dividing line) that slopes downwards when viewed from the side of the vehicle. For example, the front first fairing 22a and the front second fairing 22b are a so-called layered fairing structure where one (e.g., the front second fairing 22b) is offset relative to the other (e.g., the front first fairing 22a) in the vehicle width direction and they overlap. In this embodiment, the front second fairing 22b is offset outwards in the vehicle width direction than the front first fairing 22a. In this case, the edge of the fairing on the outer side in the vehicle width direction can be used as the front dividing line 22c. The front second fairing 22b bulges outwards in the vehicle width direction when viewed from the front-rear direction of the vehicle.
[0059] It should be noted that the front side cover 22 is not limited to a structure in which the first front cover 22a and the second front cover 22b are offset from each other in the vehicle width direction. For example, the first front cover 22a and the second front cover 22b may also form a continuous outer surface of the cover in the same plane.
[0060] The front dividing line 22c of the front side hood 22 is straight when viewed from the side of the vehicle. This straight line along the front dividing line 22c is used as the front dividing reference line 22d. If the front dividing line 22c is curved when viewed from the side of the vehicle, the straight line connecting the front and rear ends of the front dividing line 22c is used as the front dividing reference line 22d. The range of the front and rear ends of the front dividing line 22c may exclude, for example, portions that are locally inclined in opposite directions near the front and rear ends of the front dividing line 22c. In this embodiment, a line that extends continuously for more than half the length of the dividing line is used as the dividing line. Lines with different orientations that are partially inclined in opposite directions near the front and rear ends are excluded.
[0061] The rearward extension (imaginary extension) of the front split baseline 22d overlaps with the opening 31 of the rear side hood 27 when viewed from the side of the vehicle. The angle θ2 of the direction in which the front split baseline 22d slopes from the horizontal (front-high, rear-low, or rear-low, front-high) is within 45 degrees. Thus, the front split baseline 22d and the front split line 22c suppress the slope angle from the horizontal when viewed from the side of the vehicle, thereby achieving a horizontal tone and contributing to a sense of speed in the appearance. The front split baseline 22d and the front split line 22c slope from the front to the rear when viewed from the side of the vehicle, thus contributing to a dynamic appearance.
[0062] A portion of the airflow around the front cover 22 is guided along the front dividing line 22c and flows toward the opening 31 of the rear cover 27. This airflow flows smoothly rearward by branching upward and downward through the V-shaped vertically inclined surfaces 32b1 and 32d1 at the front end of the rear cover 27 (in front of the opening 31). This reduces air resistance. Furthermore, the front dividing line 22c extending in the longitudinal direction and the diamond-shaped opening 31 that suppresses vertical width also contribute to a sense of speed in appearance.
[0063] The front dividing line 22c of the front side cover 22 and the rear dividing line 27c of the rear side cover 27 are both inclined at the front and lower at the rear, and are substantially parallel to each other (for example, they do not intersect each other within the front-to-rear width of the vehicle). This creates a dynamic appearance when viewed from the side. Furthermore, the upper edge 31a (upper edge reference line 31a1) of the diamond-shaped opening 31 of the rear side cover 27 is also substantially parallel to the rear dividing line 27c (rear dividing reference line 27d) of the rear side cover 27 and the front dividing line 22c (front dividing reference line 22d) of the front side cover 22 (as described above). This results in a unified design with consistent lines.
[0064] As explained above, the motorized two-wheeled vehicle 1 in the above embodiment includes a rear side cover 27 that covers the sides of the rear of the vehicle body and a front side cover 22 that covers the sides of the front of the vehicle body. The rear side cover 27 is divided into a rear first cover 27a and a rear second cover 27b by a rear dividing line 27c that extends from the front to the rear when viewed from the side of the vehicle. The front side cover 22 is divided into a front first cover 22a and a front second cover 22b by a front dividing line 22c that extends from the front to the rear when viewed from the side of the vehicle. When viewed from the side of the vehicle, the rear dividing line 27c (or An imaginary extension of the rear dividing reference line 27d, which connects the front and rear ends of the rear dividing line 27c, passes above the upper end t1 of the rear wheel 4. In a side view of the vehicle, the imaginary extension of the front dividing line 22c (or the front dividing reference line 22d, which connects the front and rear ends of the front dividing line 22c) overlaps with the rear first cover 27a. An opening 31 facing outward in the vehicle width direction is formed in the part of the rear first cover 27a that overlaps with the imaginary extension of the front dividing line 22c (front dividing reference line 22d) in a side view of the vehicle.
[0065] According to this structure, the rear side cover 27 and the front side cover 22 have a rear dividing line 27c and a front dividing line 22c that are inclined at the front and back (i.e., rear low and front high), respectively, thus creating a dynamic design when viewed from the side of the vehicle. The rear dividing line 27c (rear dividing reference line 27d), which is inclined at the front and back, passes above the upper end t1 of the rear wheel 4, so the slope when viewed from the side of the vehicle becomes gentler (close to horizontal), creating a speed-oriented appearance. An opening 31 is formed in the rear first cover 27a at the part that overlaps with the front dividing line 22c (front dividing reference line 22d), so the driving airflow flowing along the front dividing line 22c is guided to flow appropriately around the opening 31 of the rear side cover 27, thus achieving airflow rectification along the opening 31.
[0066] In the aforementioned motorized two-wheeled vehicle 1, the opening 31 is formed with an upper edge 31a that extends from front to rear when viewed from the side of the vehicle. When viewed from the side of the vehicle, the upper edge 31a (or the upper edge reference line 31a1 connecting the front and rear ends of the upper edge 31a), the rear dividing line 27c (rear dividing reference line 27d) and the front dividing line 22c (front dividing reference line 22d) are substantially parallel to each other.
[0067] According to this structure, the upper edge 31a of the opening is substantially parallel to the dividing lines 22c and 27c of the front and rear side covers 22 and 27, thus enabling a lightweight design with continuity.
[0068] In the aforementioned motorized two-wheeled vehicle 1, the opening 31 includes an upper edge 31a extending from the front to the rear when viewed from the side of the vehicle, a second upper edge 31b extending from the front end of the upper edge 31a in a way that is lower in the front and higher in the rear, a lower edge 31c extending from the rear end of the upper edge 31a in a way that is lower in the front and higher in the rear, and a second lower edge 31d extending from the front end of the lower edge 31c in a way that is higher in the front and lower in the rear.

The rear first cover 27a has a frame-like appearance, which evokes a sense of light and airy flow.
[0072] In the aforementioned motorized two-wheeled vehicle 1, a footrest 6 for passengers is provided between the front body equipped with a front side cover 22 and the rear body equipped with a rear side cover 27. A bottom side cover 25 facing downwards is provided below the left and right outer sides of the footrest 6. The bottom side cover 25 is connected from below to the rear first cover 27a having an opening 31.
[0073] According to this structure, the bottom side cover 25 on the left and right outer sides of the bottom pedal 6 is connected from below to the rear first cover 27a with an opening 31, thereby making the rear first cover 27a with a frame-like appearance integrated with the bottom side cover 25 and thus achieving rationalization.
[0074] In the aforementioned motorized two-wheeled vehicle 1, the bottom side cover 25 faces outward in the vehicle width direction.
[0075] According to this structure, when viewed from the side of the vehicle, the frame-shaped rear first cover 27a and the bottom side cover 25 can form an integrated appearance.
[0076] In the aforementioned motorized two-wheeled vehicle 1, fastening connections 34a, 34b, and 34c are provided in front of, behind, and below the opening 31 for fixing the first rear cover 27a or the second rear cover 27b having the opening 31 to the vehicle body.
[0077] According to this structure, the frame-shaped rear first cover 27a can be securely fastened and fixed in a balanced manner.
[0078] In the aforementioned motorized two-wheeled vehicle 1, the tilt angles θ1 and θ2 of the rear dividing baseline 27d and the front dividing baseline 22d relative to the horizontal line under the side view of the vehicle are within 45 degrees.
[0079] According to this structure, compared with the case where the rear dividing baseline 27d and the front dividing baseline 22d have a large tilt angle relative to the horizontal line, it can achieve a speed-like appearance.
[0080] It should be noted that the present invention is not limited to the above-described embodiments. For example, the fairing structure of this embodiment can also be applied to straddle-type vehicles other than motorized two-wheeled vehicles. The straddle-type vehicles include all vehicles in which the driver straddles the vehicle, including not only motorized two-wheeled vehicles (including bicycles and small motorcycles with a prime mover), but also three-wheeled (including vehicles with two front wheels and one rear wheel, in addition to those with one front wheel and two rear wheels) or four-wheeled vehicles (such as four-wheeled buggies). The present invention can also be applied to vehicles whose prime mover includes an electric motor.
[0081] Furthermore, the structure described above is an example of the present invention, and the constituent elements of the embodiment can be replaced with well-known constituent elements, etc., and various changes can be made without departing from the spirit of the present invention.
