Description

This disclosure relates to a drainage structure for a saddle-type vehicle.

Patent document 1 discloses that multiple elongated drainage holes are formed in the bottom wall of the upper fender, which is attached at a position above the front wheels.

JP 2016-179784 A

However, according to the technology disclosed in Patent Document 1, water runs down the surface of the upper fender and falls from the location of the drainage hole. As a result, various parts located below the drainage hole may become wet.

Therefore, the purpose of this disclosure is to further improve the waterproofing of various parts of saddle-type vehicles.

To solve the above problem, the drainage structure for a saddle-type vehicle includes a cover having an outer surface exposed to the outside of the saddle-type vehicle, an inner surface opposite the outer surface, and a drainage hole penetrating between the outer surface and the inner surface, and a drainage guide that guides water that passes through the drainage hole from the outer surface toward a drainage position different from the drainage hole in a plan view.

This can further improve the waterproofing of various parts of saddle-type vehicles.

FIG. 1 is a plan view showing a motorcycle to which a drainage structure is applied. FIG. 2 is a side view showing the motorcycle. FIG. 3 is a partial plan view showing the motorcycle. FIG. 4 is a plan view showing the drainage guide. FIG. 5 is an exploded perspective view of the drainage guide, the side cover, and the lower side cowl. FIG. 6 is a cross-sectional view taken along line VI-VI in FIG.

{Embodiment}
Hereinafter, a drainage structure in a saddle-type vehicle according to an embodiment will be described. An example of a vehicle to which the drainage structure is applicable is a motorcycle. A motorcycle is a two-wheeled vehicle equipped with a power engine. In the following embodiment, an example in which the vehicle is a motorcycle will be described. The vehicle may be another ground-traveling vehicle, for example, a saddle-type vehicle (a three-wheeled motor vehicle, an ATV (All Terrain Vehicle), etc.) that is driven by a user, i.e., a driver, straddling a seat.

<About motorcycles>
For the sake of convenience, the motorcycle 10 will be described. FIG. 1 is a plan view showing the motorcycle 10 to which the drainage structure 31 is applied. FIG. 2 is a side view showing the motorcycle 10. FIG. 1 shows the front part of the motorcycle 10. FIG. 2 mainly shows the front cover and the fuel tank 22 of the motorcycle 10. In the following description, when referring to up/down, front/rear, and left/right, each direction is defined as follows. First, the side where the front wheel 14 of the motorcycle 10 contacts the road surface is the bottom, and the opposite side of the bottom is the top. In addition, the running direction when the motorcycle 10 runs is the front, and the opposite side of the front is the rear. Furthermore, when a user rides on the motorcycle 10 as a driver, the left and right based on the user are the left and right of the motorcycle 10. The width direction is the vehicle width direction from left to right.

In the motorcycle 10, a front wheel 14 is rotatably supported at the lower end of the front fork 12. When the motorcycle 10 is traveling, the front wheel 14 rotates at the lower end of the front fork 12. A pair of upper and lower brackets 16 are attached to the upper end of the front fork 12. The upper bracket 16 is shown in FIG. 1. A steering shaft 18 is supported by the pair of brackets 16. The steering shaft 18 is inserted into a head pipe located at the front of the body frame and supported so as to be rotatable. A handlebar 24 is supported by the upper bracket 16. When the handlebar 24 is operated, the steering shaft 18, bracket 16, and front fork 12 rotate around the axis of the head pipe. This rotation causes the front wheel 14 to rotate around the axis of the head pipe, allowing the motorcycle 10 to change its traveling direction.

The fuel tank 22, the rider's seat 23, etc. are located behind the handlebars 24. An engine is located below the fuel tank 22 and the rider's seat 23 as a power plant. The power plant of the motorcycle 10 may be an electric motor. The power plant rotates and drives a rear wheel that is provided at the rear of the body frame.

A cover 30 is provided on the motorcycle 10. The cover 30 covers at least a portion of the components of the motorcycle 10. The cover 30 has an outer surface and an inner surface. The outer surface is exposed to the outside of the motorcycle 10. The inner surface is located on the opposite side to the outer surface in the thickness direction of the cover 30. The inner surface faces the components of the motorcycle 10. The cover 30 may cover any portion of the components of the motorcycle 10.

In this embodiment, a cover 30 is provided to surround the front and both sides of the handlebars 24. The cover 30 is directly or indirectly supported by the body frame and does not move in accordance with the rotation of the handlebars 24. The cover 30 is made of resin or the like. In this embodiment, the cover 30 includes a front cowl 26, a side cover 40, an upper side cowl 50, and a lower side cowl 60. The side cover 40, the upper side cowl 50, and the lower side cowl 60 are provided on both sides of the motorcycle 10 in the vehicle width direction. The front cowl 26 is directly or indirectly attached to the body frame so as to cover the front outer side of the handlebars 24. A windshield 25 is supported at the rear of the front cowl 26 in the center of the width direction. The side cover 40 covers the outer side of the motorcycle 10 in the vehicle width direction in a plan view. In this embodiment, the side cover 40 covers an area that is on the outer side of the handlebars 24 in the vehicle width direction and extends in the front-rear direction. The side cover 40 is attached directly or indirectly to the body frame. The upper side cowl 50 and the lower side cowl 60 are attached directly or indirectly to the body frame at a position rearward of the front cowl 26 and below the side cover 40 so as to cover the motorcycle 10 from the outside in the vehicle width direction. The upper side cowl 50 covers the area above the lower side cowl 60.

It is arbitrary which areas of the cover 30 are integrated and which parts are divided. For example, the entire cover 30 may be molded integrally from the same resin. Also, some parts of the front cowl 26, side cover 40, upper side cowl 50, and lower side cowl 60 may be molded integrally from the same resin. Also, any part of the front cowl 26, side cover 40, upper side cowl 50, and lower side cowl 60 may be divided into smaller parts. Each part of the cover 30 is fixed directly or indirectly to the vehicle frame, for example, by screws S, an insert structure, etc.

The gauge 27 is located behind the front cowl 26 and inside the windshield 25. The gauge 27 is a display unit that displays vehicle information such as speed and engine RPM. The gauge 27 may display vehicle information in an analog format, a digital format, or a combination of analog and digital formats.

<Drainage structure>
The drainage structure 31 in the motorcycle 10 will be described. In this embodiment, an example in which the side cover 40 has drainage holes 46 will be described. Fig. 3 is a partial plan view showing the motorcycle 10. Fig. 3 mainly shows the side cover 40, the upper side cowl 50, and the lower side cowl 60. Below, focusing on the left side portion of the motorcycle 10, the left side cover 40, the upper side cowl 50, and the lower side cowl 60 will be described. The drainage structure may be incorporated into either the left or right side of the motorcycle 10, or may be incorporated into both the left and right sides.

As shown in Figs. 1 to 3, the side cover 40 includes a first upper cover part 42, a second upper cover part 44, and a valley part 43. The side cover 40 may be a member that is molded integrally from the same resin. The rear edge of the first upper cover part 42 is lower than the front edge. The second upper cover part 44 is located rearward of the first upper cover part 42. The rear edge of the second upper cover part 44 is higher than the front edge. The valley part 43 connects the rear edge of the first upper cover part 42 and the front edge of the second upper cover part 44. Therefore, the valley part 43 forms a valley that extends along the boundary between the first upper cover part 42 and the second upper cover part 44.

More specifically, the first upper cover part 42 is located rearward of the vehicle width direction outer portion of the rear edge of the front cowl 26. In the front-rear direction, the first upper cover part 42 is located at the same position as the gauge 27 or rearward of the gauge 27. The first upper cover part 42 is located forward of the passenger seat 23. The first upper cover part 42 may be located forward of the fuel tank 22 or may be located forward of the handlebars 24. The first upper cover part 42 may be located below the handlebars 24. The first upper cover part 42 may be located at the same height as the passenger seat 23 or may be located at a higher position than the passenger seat 23. The first upper cover part 42 is formed in a flat shape. The front edge of the first upper cover part 42 is in contact with the vehicle width direction outer portion of the rear edge of the front cowl 26. The vehicle width direction outer edge of the first upper cover part 42 is in contact with the upper edge of the upper side cowl 50. The inner edge of the first upper cover part 42 in the vehicle width direction forms part of the edge surrounding the opening in which the front forks 12 are disposed. The rear edge of the first upper cover part 42 is V-shaped and convex downward.

An interface device is supported on the first upper cover part 42. The interface device is a connection device for transmitting information, signals, or power between the motorcycle 10 and an external device or a rider. The interface device may be, for example, a switch, a charging connector, or a display device. In FIG. 3, switches 48a and 48b are exemplified as the interface device. The switch 48a is a round switch, and the switch 48b is a square switch. The switches 48a and 48b are directly or indirectly supported on the body frame on the front side of the first upper cover part 42. The first upper cover part 42 has holes 42h1 and 42h2 for arranging the switches 48a and 48b. By arranging the switches 48a and 48b in the holes 42h1 and 42h2, the switches 48a and 48b are supported at fixed positions in the direction in which the first upper cover part 42 extends. In addition, in FIG. 1, the second upper cover part 44 on the right side supports a charging connector 48c as an interface device. The charging connector 48c may be covered by a cover 48d.

The first upper cover part 42 is located forward and below the face of the rider sitting on the rider's seat 23, and faces diagonally upward. By supporting the interface device on this first upper cover part 42, the rider can easily operate and see the interface device. In highly information-rich motorcycles 10, the number and mounting area of interface devices mounted are increasing. For this reason, the installation space for the gauges 27 located in the front center of the handlebars 24 and the installation space for the switches around the handlebar grips may not be enough area to mount the interface devices. The first upper cover part 42 can be used as a space to mount the increasing number of interface devices.

The second upper cover part 44 is located rearward relative to the first upper cover part 42. The first upper cover part 42 passes outside the handlebar 24 in the vehicle width direction and extends toward the side of the center in the front-rear direction of the fuel tank 22. The front edge of the second upper cover part 44 is V-shaped with a downward convexity and is integrally connected to the rear edge of the first upper cover part 42. The second upper cover part 44 includes a V-groove part 44a extending rearward from the front edge. The V-groove part 44a gradually becomes shallower from the front edge of the second upper cover part 44 toward the rear. The front end of the deepest part of the V-groove part 44a is lower than the rear end. The second upper cover part 44 includes a mountain-shaped part 44b connected to the rear part of the V-groove part 44a. The mountain-shaped part 44b is in an inverted V shape with the highest point at the center in the width direction. The mountain-shaped portion 44b curves rearward from the rear of the V-shaped groove portion 44a toward the center in the vehicle width direction, and reaches the fuel tank 22. The outer edge of the second upper cover portion 44 in the vehicle width direction is in contact with the upper edge of the upper side cowl 50. The inner edge of the second upper cover portion 44 in the vehicle width direction forms part of the edge surrounding the opening in which the front fork 12 is disposed.

It may be considered that the first upper cover part 42 is a part for placing an interface device facing the rider, and the second upper cover part 44 is a part that extends rearward from the lower edge of the first upper cover part 42 and forms a surface for smoothly flowing the wind backward. In this way, it is considered that a valley part 43 that is V-shaped when the motorcycle 10 is viewed from the side is formed between the cover part for creating the surface facing the rider and the cover part for forming the surface for smoothly flowing the wind backward.

The valley portion 43 extends along the boundary between the rear edge of the first upper cover portion 42 and the front edge of the second upper cover portion 44. Therefore, the valley portion 43 forms a V-shaped groove formed by a portion near the rear edge of the first upper cover portion 42 and a portion near the front edge of the second upper cover portion 44. The valley portion 43 gradually descends from the inner portion of the rear edge of the first upper cover portion 42 toward the outer side in the vehicle width direction, reaches the deepest portion 43D located at the lowest position, and extends gradually upward from the deepest portion toward the outer side in the vehicle width direction. Note that in this embodiment, the inner edge of the valley portion 43 in the vehicle width direction is lower than the outer edge in the vehicle width direction.

Suppose the motorcycle 10 is exposed to rainwater or the like. In this case, water that falls onto the first upper cover part 42 heads toward the valley part 43, and water that falls into the V-groove part 44a of the second upper cover part 44 also heads toward the valley part 43. When water accumulates in the valley part 43, it is considered that the water will run down the valley part 43 and overflow from the inner edge of the valley part 43 in the vehicle width direction.

Here, it is assumed that various parts of the motorcycle 10 are located lower than the side cover 40. For example, it is assumed that the air cleaner 49c is located lower than the side cover 40 and closer to the center in the vehicle width direction. It is assumed that the air intake 49d of the air cleaner 49c faces forward so as to easily take in air while driving. It is assumed that the air intake 49d is located at the same position as the valley portion 43 or behind the valley portion 43 in the front-rear direction. For this reason, it is assumed that water dripping from the valley portion 43 will enter the air intake 49d due to the influence of the wind during driving, etc. Also, for example, it is assumed that the charcoal canister 49a and the purge valve 49b are located directly below the side cover 40. In this case, it is assumed that the water overflowing from the valley portion 43 will splash on the charcoal canister 49a and the purge valve 49b.

In this embodiment, in order to form a drainage path different from the water drainage path by the outer surface 40f1 of the side cover 40, in this embodiment, a drainage hole 46 is formed in the side cover 40 and a drainage guide 70 is positioned below the drainage hole 46. The drainage hole 46 penetrates between the outer surface 40f1 and the inner surface 40f2 of the side cover 40. Therefore, water running down the outer surface 40f1 of the side cover 40 penetrates the side cover 40 and is guided to the inner surface 40f2 side. The drainage guide 70 guides the water that has passed through the drainage hole 46 toward a drainage position P different from the drainage hole 46 in a plan view.

In this embodiment, the drain hole 46 is formed in the valley portion 43. More specifically, the drain hole 46 is formed in the deepest portion 43D of the valley portion 43. The drain hole 46 may be formed in a portion of the valley portion 43 other than the deepest portion 43D. A funnel-shaped guide surface 46a that gradually narrows toward the drain hole 46 may be formed around the upper opening of the drain hole 46 in the side cover 40. The guide surface 46a can more reliably guide water toward the drain hole 46. An annular protrusion 46b that protrudes downward may be formed around the lower opening of the drain hole 46 in the side cover 40. The annular protrusion 46b is shown in FIG. 6. The annular protrusion 46b makes it easier for water that has passed through the drain hole 46 to drip downward from the lowest end of the annular protrusion 46b, and is less likely to flow along the inner surface 40f2 of the side cover 40.

In this embodiment, the side cover 40 may be understood to be a cover having the drainage holes 46. Alternatively, the combination of the side cover 40 and the upper side cowl 50 may be understood to be a cover having the drainage holes 46.

Figure 4 is a plan view showing the drainage guide 70. The side cover 40 and the lower side cowl 60 are omitted from Figure 4. Figure 5 is an exploded perspective view of the drainage guide 70, the side cover 40, and the lower side cowl 60.

2, 4, and 5, the drain guide 70 is located in a position to receive water drained from the drain hole 46. For example, in a plan view, at least a portion of the drain guide 70 is located directly below the drain hole 46. In a plan view, at least a portion of the drain guide 70 may overlap at least one of the electrical equipment and the wiring. The drain guide 70 enhances the waterproofing effect for at least one of the electrical equipment and the wiring. For example, in a plan view, the portion of the drain guide 70 located directly below the drain hole 46 may overlap at least one of the electrical equipment and the wiring. This prevents water that has passed through the drain hole 46 from falling directly onto at least one of the electrical equipment and the wiring, enhancing the waterproofing effect for at least one of the electrical equipment and the wiring.

The drain guide 70 may be located between the drain hole 46 and the air intake 49d in the vertical direction. This makes it difficult for water that has passed through the drain hole 46 to reach the air intake 49d. It is preferable that the drain guide 70 be located between the drain hole 46 and the air intake 49d on a straight line connecting the drain hole 46 and the air intake 49d, but this is not essential. As described above, it is sufficient that the drain guide 70 is located between the drain hole 46 and the air intake 49d in the vertical positional relationship.

The drain guide 70 has a bottom 71 and a peripheral wall 72. The bottom 71 is located below the drain hole 46, and a part of the bottom 71 is located directly below the drain hole 46. The peripheral wall 72 extends around the bottom 71, and in this embodiment, along the front edge, rear edge, and inner edge of the bottom 71 in the vehicle width direction.

More specifically, the bottom 71 includes a first bottom 71a and a second bottom 71b. The first bottom 71a includes a square portion extending below the drainage hole 46 and an extension portion extending from the rear portion of the square portion to the outside in the vehicle width direction. The second bottom 71b is located outside the square portion of the first bottom 71a in the vehicle width direction and in front of the extension portion. The second bottom 71b is located at a lower position than the first bottom 71a. The first bottom 71a and the second bottom 71b are connected via a step wall 73.

The peripheral wall portion 72 surrounds the front edge, the inner edge in the vehicle width direction, and the rear edge of the first bottom portion 71a. A portion of the inner edge in the vehicle width direction of the first bottom portion 71a of the peripheral wall portion 72 is recessed. This recess corresponds to the shape of the valley portion 43. The drainage hole 46 is located on the outer side of the recess in the vehicle width direction in a plan view. Therefore, water that passes through the drainage hole 46 falls onto the first bottom portion 71a.

The outer edge of the first bottom 71a in the vehicle width direction may be lower than the inner edge in the vehicle width direction, and the outer edge of the second bottom 71b in the vehicle width direction may be lower than the inner edge in the vehicle width direction. In other words, the first bottom 71a and the second bottom 71b may be inclined downward toward the outside in the vehicle width direction. In this case, water that falls onto the first bottom 71a flows outward in the vehicle width direction along the first bottom 71a, or flows outward in the vehicle width direction via the first bottom 71a and the second bottom 71b.

The drainage extension 74 is located along the outer edges of the first bottom 71a, the step wall, and the second bottom 71b in the vehicle width direction. The drainage extension 74 is a long, thin plate-like portion that protrudes toward the outside in the vehicle width direction. The drainage extension 74 also inclines downward toward the outside in the vehicle width direction. Water running down the first bottom 71a and the second bottom 71b is guided outside the first bottom 71a and the second bottom 71b by the extension dimension of the drainage extension 74. In this embodiment, the position of the outer edge in the vehicle width direction of the drainage extension 74 is the drainage position P. The drainage position P is located outside the drainage hole 46 in the vehicle width direction. The drainage extension 74 may be omitted. In this case, water may be drained with the outer edges of the first bottom 71a and the second bottom 71b in the vehicle width direction as the drainage position.

It is preferable that the first bottom 71a and the second bottom 71b are inclined downward toward the rear. This prevents water from flowing forward and makes it easier for water to flow outward along the step wall or the rear peripheral wall 72.

A wiring recess is formed in the front edge of the first bottom 71a of the peripheral wall 72. A wiring hole 71bh is formed in the front part of the second bottom 71b. The wiring member 75 passes through the wiring recess, passes above the first bottom 71a and the second bottom 71b, and is routed so as to pass through the wiring hole 71bh. The wiring hole 71bh is located higher in the direction of gravity than the drainage position P. This makes it difficult for water to enter the wiring hole 71bh. By routing the wiring member 75 as described above, the space above the drainage guide 70 can be used as a space for arranging the wiring member 75. It is not essential that the wiring member 75 pass through this path.

The relationship between the drainage structure 31, the upper side cowl 50, and the lower side cowl 60 will now be described. Figure 6 is a cross-sectional view taken along line VI-VI in Figure 2.

As shown in Figures 2 to 6, the lower side cowl 60 has a lower cover body 62. The lower cover body 62 has a lower surface 62f that extends below the outer surface 40f1 of the side cover 40. The lower surface 62f faces outward in the vehicle width direction at a position that is outside and lower than the side cover 40 in the vehicle width direction. The drainage guide 70 is integrally formed with the lower cover body 62.

In this embodiment, the lower cover body 62 extends from the rear edge of the front cowl 26 to a position below the fuel tank 22. A drain guide 70 extends from the front portion of the upper edge of the lower cover body 62 toward the inside in the vehicle width direction. The lower cover body 62 and the drain guide 70 may be molded integrally from the same resin, for example. The drain extension 74 extends from the lower surface of the lower cover body 62 outward in the vehicle width direction beyond 62f.

A ridge portion 62a extends along the front-rear direction from the vertical middle portion of the lower cover body 62. The ridge portion 62a of the lower cover body 62 protrudes outward in the vehicle width direction beyond the vertical regions of the ridge portion 62a.

The upper side cowl 50 extends downward from the upper part of the rear edge of the front cowl 26, passing under the fuel tank 22, toward the passenger seat 23. The upper side cowl 50 extends downward from the outer edge of the side cover 40 in the vehicle width direction, and covers the upper region of the lower cover body 62 from the outside in the vehicle width direction. In other words, the upper side cowl 50 covers the space between the side cover 40 and the drainage guide 70 from the outside in the vehicle width direction. The upper side cowl 50 also covers the drainage guide 70 and the portion where the drainage guide 70 and the lower cover body 62 are connected from the outside in the vehicle width direction.

The drainage extension 74 is covered by the upper side cowl 50. A gap large enough for water to pass through is formed between the leading edge of the drainage extension 74 and the inner surface of the upper side cowl 50. The drainage extension 74 closes the gap between the upper side cowl 50 and the lower cover body 62. As a result, when the upper side cowl 50 and the lower cover body 62 are observed from below, the drainage extension 74 hides the depth of the gap.

The lower edge of the upper side cowl 50 may extend to a position along the ridge portion 62a of the lower cover body 62 or to a position near the ridge portion 62a. For example, the lower edge of the upper side cowl 50 may be located within 3 cm, preferably 2 cm, and more preferably 1 cm of the ridge portion 62a of the lower cover body 62.

The upper side cowl 50 may have a knee grip portion 58 that is recessed inward and where the rider's knees K are placed. In this embodiment, a recess 22g that recesses inward is formed in the rear and lower portion of the side of the fuel tank 22. A knee grip portion 58 is formed in the rear portion of the upper side cowl 50, continuing diagonally downward and forward from the recess 22g. The rider can place his knees K in the recess 22g and the knee grip portion 58 to stably hold the fuel tank 22 and the left and right upper side cowls 50.

The water drainage position P is located forward of the knee-grip portion 58. The water drainage position P may be located further outboard in the vehicle width direction than the bottom of the knee-grip portion 58. Note that a step on which the feet are placed is located below the knee-grip portion. Therefore, the driver's feet are positioned downward from the knee-grip portion 58. The water drainage position P is located at a position forward and away from the driver's feet.

In this embodiment, the side cover 40 and the upper side cowl 50 are separate bodies. The side cover 40 and the upper side cowl 50 may be integrally molded parts made of the same resin. In other words, the drain position P is located in a forward position away from the driver.

Explain the drainage operation.

Suppose that rainwater falls on the side cover 40 in a rainy environment. The rainwater flows down according to gravity along the outer surfaces of the first upper cover part 42 and the second upper cover part 44 as shown by the arrow F1. The flow of rainwater may be affected by the wind during driving. The rainwater flows toward the valley part 43, and when it reaches the deepest part 43D, it passes through the drainage hole 46 as shown by the arrow F2 and falls below the side cover 40. The falling water reaches the bottom part 71 of the drainage guide 70, and flows outward in the vehicle width direction according to the inclination of the bottom part 71 as shown by the arrow F3. When the water reaches the outer edge of the bottom part 71 in the vehicle width direction, it further flows outward in the vehicle width direction along the drainage extension part 74 as shown by the arrow F4, and falls from the tip part of the drainage extension part 74 as shown by the arrow F5. Furthermore, as shown by arrow F6, the water passes between the upper side cowl 50 and the lower cover body 62 of the lower side cowl 60, and is discharged from the motorcycle 10 to the outside between the lower edge of the upper side cowl 50 and the ridge portion 62a. For example, if the water falls naturally, it may fall downward from the ridge portion 62a. When the motorcycle 10 is traveling, the water may be blown away by the wind between the lower edge of the upper side cowl 50 and the ridge portion 62a. In either case, the water is discharged outside the outer surface of the lower side cowl 60, and is unlikely to flow into the charcoal canister 49a, the purge valve 49b, or the intake port 49d of the air cleaner 49c.

With the drainage structure 31 configured as described above, water running down the outer surface 40f1 of the side cover 40 flows through the drainage holes 46 toward the inner surface 40f2 of the side cover 40, and is drained from the drainage position P via the drainage guide 70. Therefore, the water is drained from the drainage position P, avoiding a position where it would fall onto various components inside the side cover 40. This improves the waterproofing of various components of the motorcycle 10.

In other words, water does not flow along the outer surface 40f1 of a cover such as the side cover 40, but is guided through the drainage holes 46 located midway along the outer surface 40f1 to the inner surface 40f2 of the cover. Furthermore, water is guided by the drainage guide 70 from the drainage holes 46 toward the drainage position P where water is less likely to get on various parts of the motorcycle 10. This improves the waterproofing of various parts of the motorcycle 10. Note that this effect can be achieved even without the following configurations.

The side cover 40 also includes a valley portion 43, and the drainage holes 46 are formed in the valley portion 43. This allows water present on the first upper cover portion 42 and the second upper cover portion 44 to be collected in the valley portion 43 and drained through the drainage holes 46. This makes it difficult for water on the side cover 40 to fall from places other than the drainage holes 46, further improving the waterproofing of various parts of the motorcycle 10.

In addition, a drain guide 70 is located between the drain hole 46 and the air intake 49d of the air cleaner 49c in the vertical direction. Therefore, water that falls through the drain hole 46 is blocked by the drain guide 70 and is unlikely to flow toward the air intake 49d. This prevents water from the drain hole 46 from entering the air cleaner 49c.

The interface device is supported on the first upper cover part 42. Therefore, the interface device can be supported by the first upper cover part 42 facing the driver. It is suitable for the first upper cover part 42 to face diagonally upward from the rear. In this case, it is considered that a valley part 43 where water tends to accumulate will be formed at the rear edge of the first upper cover part 42. By forming a drainage hole 46 in the valley part 43, water that tends to accumulate due to the provision of the first upper cover part 42 that supports the interface device can be effectively drained to a position where it is unlikely to splash on various components.

In addition, because the drainage position P is located on the outer side of the drainage hole 46 in the vehicle width direction, water is less likely to get on the internal parts of the motorcycle 10.

In addition, the water drainage position P is located forward of the knee grip portion 58. Because the driver's knees K are positioned in the knee grip portion 58, which is recessed inward, water drained from the water drainage position P is unlikely to splash onto the driver's knees K.

In addition, because the drainage guide 70 is integrally formed with the lower cover body 62, the number of parts can be reduced compared to when an additional part is provided for the drainage guide 70.

In addition, because the upper side cowl 50 covers the drainage guide 70 and the portion where the drainage guide 70 and the lower cover body 62 are connected, the drainage position P is hidden between the upper side cowl 50 and the lower cover body 62, making the drainage guide 70 and the drainage position P less noticeable.

{Modification}
In the above embodiment, the drainage holes 46 are formed in the side cover 40. The cover in which the drainage holes are formed does not have to be the side cover. For example, the drainage holes may be formed in the front cowl 26, the lower side cowl 60, or a rear cover of the motorcycle 10.

It is not essential that the drainage holes 46 are formed in the valley portions 43. For example, the drainage holes may be formed in positions on the side cover other than the valley portions 43. For example, the drainage holes may be formed in the middle of the first upper cover portion 42 or the second upper cover portion 44. The drainage holes may be formed in positions that tend to act as a water flow path or positions where water tends to accumulate. For example, the drainage holes may be formed in the bottom of a groove or recess.

The shape of the drainage guide 70 is not limited to the shape described in the above embodiment. For example, the drainage guide may be semi-cylindrical or dish-shaped. The drainage guide may extend with a curved semi-cylindrical groove to reach a position suitable for drainage. Furthermore, the drainage position of the drainage guide is not limited to the above example. The drainage guide may guide water that has passed through the drainage hole backward or forward from the position of the drainage hole.

The configurations described in the above embodiment and each modified example can be combined as appropriate as long as they are not mutually inconsistent.

This disclosure discloses the following aspects:

The first aspect is a drainage structure for a saddle-type vehicle, comprising a cover having an outer surface exposed to the outside of the saddle-type vehicle, an inner surface opposite the outer surface, and a drainage hole penetrating between the outer surface and the inner surface, and a drainage guide that guides water that has passed through the drainage hole from the outer surface toward a drainage position different from the drainage hole in a plan view.

This drainage structure allows water running down the outer surface of the cover to avoid falling onto various components and is instead drained through the drainage holes and drainage guides. This improves the waterproofing of various components of the saddle-type vehicle.

The second aspect is a drainage structure for a saddle-type vehicle according to the first aspect, in which the cover has a side cover covering the outside of the width direction of the saddle-type vehicle, the side cover including a first upper cover part arranged so that its rear edge is lower than its front edge, a second upper cover part arranged so that its rear edge is higher than its front edge, and a valley part connecting the rear edge of the first upper cover part and the front edge of the second upper cover part, and the drainage hole is formed in the valley part. In this case, water above the first upper cover part and the second upper cover part can be collected in the valley part and drained.

The third aspect is a drainage structure for a saddle-type vehicle according to the first or second aspect, further comprising an air cleaner having an intake port, and the drainage guide is positioned between the drainage hole and the intake port in the vertical direction. In this case, the drainage guide can prevent water from the drainage hole from entering the air cleaner.

The fourth aspect is a drainage structure for a saddle-type vehicle according to the second aspect, further comprising an interface device supported by the first upper cover part. In this case, the interface device facing the driver can be supported by the first upper cover part.

The fifth aspect is a drainage structure for a saddle-type vehicle according to any one of the first to fourth aspects, in which the drainage position is located on the outer side of the vehicle width direction of the saddle-type vehicle relative to the drainage hole. In this case, water is discharged to the outer side of the vehicle width direction of the saddle-type vehicle, so that water is less likely to splash on internal parts of the saddle-type vehicle.

The sixth aspect is a drainage structure for a saddle-type vehicle according to any one of the first to fifth aspects, in which the cover has a knee-grip portion that is recessed inward and where the driver's knees are placed, and the drainage position is located forward of the knee-grip portion. In this case, because the driver's knees are placed in the knee-grip portion that is recessed inward, water drained from the drainage position is unlikely to splash on the driver.

The seventh aspect is a drainage structure for a saddle-type vehicle according to any one of the first to sixth aspects, further comprising a lower cover body having a lower surface extending below the outer surface, and the drainage guide being integrally formed with the lower cover body. In this case, since the drainage guide is integrally formed with the lower cover body, the number of parts can be reduced compared to when the drainage guide is prepared as a separate part.

The eighth aspect is the drainage structure for a saddle-type vehicle according to the seventh aspect, in which the cover covers the drainage guide and the portion where the drainage guide and the lower cover body are connected. In this case, the drainage position is hidden between the cover and the lower cover body, making the drainage guide and drainage position less noticeable.

The above description is illustrative in all respects and does not limit the present invention. It is understood that countless variations not illustrated can be envisioned without departing from the scope of the present invention.
