Description

Technical Field

[0001] This invention relates to the air intake structure of a saddle-type vehicle. Background Technology

[0002] In the past, in saddle-type vehicles, it is known that a structure is used to draw in air from the front of the vehicle and supply it to the engine (for example, see Patent Document 1). In Patent Document 1, the air intake duct opens forward at the rear of the front riser.

[0005] Patent Document 1: Japanese Patent No. 4139394 Summary of the Invention

[0006] The problem that the invention aims to solve

[0007] When the air duct opens behind the front riser, structures at the front of the vehicle, such as the headlights, interfere with the opening of the air duct when viewed directly, making it difficult for airflow to enter the duct. Furthermore, if an air intake is installed at the front of the vehicle to avoid this, it may also negatively impact the vehicle's appearance as the intake is easily noticeable from the front.

[0008] The present invention was made in view of the above circumstances, and its object is to provide an air intake structure for a saddle-type vehicle with an air intake that is not conspicuous and can easily draw in driving air.

[0009] Methods for solving problems

[0010] This specification contains the entire contents of Japanese Patent Application No. 2021-022551, filed on February 16, 2021.

[0011] The air intake structure of a saddle-riding vehicle is an air intake structure in which an air intake pipe is arranged between the front forks, characterized in that the air intake pipe has an air intake port that opens forward, and a first lighting device is arranged in front of the front fork, the first lighting device extending along the outer periphery of the air intake port.

[0012] In the aforementioned structure, the first lighting device may have a pair of light-emitting portions in the vehicle width direction, wherein, when viewed from the front, the pair of light-emitting portions in the vehicle width direction have at least one portion disposed above and below the air intake.

[0013] Alternatively, in the above structure, when viewed from the front, the following portions of the air intake constitute at least a part of the opening shape of the air intake: an outer edge in the vehicle width direction located at the outer end of the vehicle width direction; an upper edge extending from the upper end of the outer edge in the vehicle width direction; and a lower edge extending from the lower end of the outer edge in the vehicle width direction, wherein the first lighting fixture is arranged along the outer edge in the vehicle width direction, the upper edge, and the lower edge.

[0014] Alternatively, in the above structure, a second lighting device may be provided inside the first lighting device, and the air inlet may be located outside the second lighting device in the vehicle width direction.

[0015] Alternatively, in the above structure, the second lighting fixture may be in a convex shape that protrudes forward.

[0016] Alternatively, in the above structure, the second lighting fixture may be positioned below the area surrounded by the first lighting fixture.

[0017] Alternatively, a support frame may be provided above the second lighting fixture to support both the first and second lighting fixtures.

[0018] In addition, in the above structure, the air intake can also be configured such that, when viewed from the front, the width increases towards the rear.

[0019] Alternatively, in the above structure, the first lighting fixture may be configured such that its width increases towards the rear.

[0020] Alternatively, in the above structure, the support frame may have a support portion that supports the fork and the second lighting fixture, without the first lighting fixture being disposed on the support portion.

[0021] Invention Effects

[0022] The air intake structure of a saddle-riding vehicle is characterized by an air intake pipe disposed between the front forks, wherein the air intake pipe has an air intake opening facing forward, and a first lighting device is disposed in front of the front fork, extending along the outer periphery of the air intake. According to this structure, the easily noticeable first lighting device extends along the outer periphery of the air intake; therefore, the air intake can be positioned at the front without being conspicuous, facilitating the intake of riding air.

[0023] In the above structure, the first lighting device may also have a pair of light-emitting portions in the vehicle width direction, wherein, when viewed from the front, the pair of light-emitting portions in the vehicle width direction have portions disposed above and below the air intake. According to this structure, the first lighting device is disposed on most of the outer periphery of the air intake, thus allowing the air intake to be positioned at the front and making it less conspicuous.

[0024] Alternatively, in the above structure, when viewed from the front, the following portions of the air intake may constitute at least a part of the opening shape of the air intake: an outer edge in the vehicle width direction located at the outer end of the vehicle width direction; an upper edge extending from the upper end of the outer edge in the vehicle width direction; and a lower edge extending from the lower end of the outer edge in the vehicle width direction, wherein the first lighting fixture is arranged along the outer edge in the vehicle width direction, the upper edge, and the lower edge. According to this structure, the first lighting fixture is arranged on most of the outer periphery of the air intake, thus allowing the air intake to be positioned at the front and making it less conspicuous.

[0025] Alternatively, in the above structure, a second lighting fixture may be located inside the first lighting fixture, and the air intake may be located outside the second lighting fixture in the vehicle width direction. According to this structure, the air intake is sandwiched between the easily noticeable first and second lighting fixtures, thus making the air intake relatively less conspicuous.

[0026] Alternatively, in the above structure, the second lighting fixture may be in a convex shape that protrudes forward.

[0027] According to this structure, the convex shape of the second lighting device can be used to separate the driving air in the vehicle width direction, and the driving air can be easily drawn into the air intake in the vehicle width direction of the second lighting device.

[0028] Alternatively, in the above configuration, the second lighting fixture can be positioned below the area surrounded by the first lighting fixture. This configuration facilitates the intake of air for driving.

[0029] Alternatively, a support frame can be provided above the second lighting fixture to support both the first and second lighting fixtures. With this structure, stable support can be achieved by supporting the first and second lighting fixtures from above.

[0030] Furthermore, in the above structure, the air intake can also be configured such that, when viewed from the front, its width increases towards the rear. With this structure, it is easy to draw in airflow that is deviated from the front end to the rear of the air intake.

[0031] Alternatively, in the above structure, the first lighting fixture can be configured such that its width increases towards the rear. This configuration facilitates the intake of air during driving.

[0032] Alternatively, in the above structure, the support frame may have a support portion that supports the fork and the second lighting fixture, but the first lighting fixture is not disposed on the support portion. This structure contributes to the increased strength of the support portion. Attached Figure Description

[0054] Figure 2 This is a right-side view of the periphery of the headlight 40 of a saddle-type vehicle 10 according to an embodiment of the present invention. Figure 3 This is a perspective view taken from the right front of the periphery of the headlight 40 of the saddle-type vehicle 10 according to an embodiment of the present invention.

[0055] The saddle-mounted vehicle 10 includes a headlight 40 and an instrument display (instrument unit) 50. The headlight 40 is supported on the front fork 14 via a headlight bracket 46. The instrument display 50 is supported on the front fork 14 via an instrument bracket 56.

[0056] The front fork 14 has a steering shaft 31 that is rotatably supported on the front seat tube 18 (see reference). Figure 3 A top axle 32 extending in the left-right direction (vehicle width direction) is fixed to the upper end of the steering axle 31. A bottom axle 33 extending in the left-right direction is fixed to the lower end of the steering axle 31. A pair of left and right fork tubes 34 extending in the up-down direction are supported by the top axle 32 and the bottom axle 33. Figure 1 As shown, the fork tube 34 is tilted backward relative to the vertical direction by an amount equivalent to the tilt angle set for the saddle-type vehicle 10.

[0057] The fork tube 34 of this embodiment is configured to include: an upper tube 35 forming the upper part, a lower tube 36 slidably fitted inside the upper tube 35, and an axle support member 37 fixed to the lower end of the lower tube 36. The axle 13a is supported by the axle support member 37. The lower tube 36 forms the lower part of the fork tube 34.

[0058] The front fork 14 of this embodiment is formed by the steering shaft 31, top bridge 32, bottom bridge 33 and a pair of left and right fork tubes 34.

[0059] The top bridge 32 has a top bridge body 32A extending along the vehicle width direction. Fork tubes 34 are fixed to both ends of the top bridge body 32A. A handle post 32B protruding upwards is provided at the center of the top bridge body 32A in the left-right direction (see reference). Figure 2 (etc.). A handle 21 extending in the left-right direction is fixed to the handle column 32B.

[0060] like Figure 3 As shown, a bridge support portion 32C is formed at the front of the main body 32A of the top bridge. The bridge support portion 32C has a pair of left and right support legs 32D and 32E protruding forward from the main body 32A of the top bridge. A columnar fastening portion 32F extending in the left and right direction is supported at the front end of the support legs 32D and 32E. A pair of left and right fastening members 71 extending in the left and right direction are fastened to the fastening portion 32F from the left and right directions, and the headlight support 46 and the instrument support 56 are fastened together to the fastening portion 32F. The fastening members 71 are, for example, bolts.

[0061] Figure 4 This is a front view showing the periphery of the headlight 40 of a saddle-type vehicle 10 according to an embodiment of the present invention.

[0062] The headlight bracket 46 in this embodiment is a metal bracket. The headlight bracket 46 has a central portion (bracket portion) 46A extending downward from the bridge bracket portion 32C. The central portion 46A is formed with a U-shaped cross-section. The front end of the central portion 46A tapers, and when viewed from the front, its width decreases towards the lower end (end side). When viewed from the side, the central portion 46A curves upward in a convex shape and extends downward (see reference). Figure 2 ).

[0063] At the center 46A, a pair of fixing portions 46A1 are formed corresponding to the upper end of the U-shape. The fixing portions 46A1 are formed as cylindrical sections extending in the left-right direction. A reinforcing plate 46A2 protruding forward and upward is formed on the outer periphery of the fixing portions 46A1 (see reference). Figure 3 ).

[0064] The fixing part 46A1 is arranged on the left and right sides of the bridge support part 32C, and is supported on the fastening part 32F by various fastening members 71. A lighting fixture support part 46A3 (see reference) is formed in the lower part of the central part 46A, which is shaped by a portion missing from the front to the rear. Figure 3 ).

[0065] A pair of side portions 46B and 46C are provided on the left and right sides of the central portion 46A. The side portions 46B and 46C are connected to a position above the lighting fixture support portion 46A3. The left side portion 46B and the right side portion 46C are symmetrical.

[0066] exist Figure 4 In the front view shown, the side portions 46B and 46C protrude outwards from the rear of the central portion 46A in the left and right directions, and extend downwards towards the central portion in the left and right directions while bending convexly in the left and right directions.

[0067] In this embodiment, the side portions 46B and 46C are connected to the lower end of the central portion 46A. In other words, the side portions 46B and 46C in this embodiment are formed by the left side portion 46B and the right side portion 46C together to form an open-topped, roughly U-shaped (or roughly C-shaped) shape, and the upper end of the open end of the roughly U-shaped (or roughly C-shaped) shape is connected to the upper rear part of the central portion 46A from the left and right sides.

[0068] An air intake 61 for drawing in driving air supplied to the power unit 12 is formed between the central portion 46A, the left side portion 46B, and the right side portion 46C. The air intake 61 is formed by the enclosing shape of the central portion 46A, the left side portion 46B, and the right side portion 46C. The air intake 61 is divided left and right by the central portion 46A, having a left air intake 61A and a right air intake 61B. Here, the side portions 46B and 46C tilt forward as they move downwards when viewed from the side (see reference). Figure 2The air intakes 61, namely the left air intake 61A and the right air intake 61B, are configured such that, when viewed from the front, the width increases towards the rear in the left-right direction. Compared to cases where the width does not increase towards the rear, the air intakes 61 can more easily draw in driving air.

[0069] exist Figure 4 In the front view shown, the opening shapes of the left and right air intakes 61A and 61B in this embodiment are formed by the following parts: left and right outer edges 61A1 and 61B1 provided at the outer ends in the left and right directions; upper edges 61A2 and 61B2 extending from the upper ends of the left and right outer edges 61A1 and 61B1; lower edges 61A3 and 61B3 extending from the lower ends of the left and right outer edges 61A1 and 61B1; and left and right inner edges 61A4 and 61B4 connecting the inner ends of the upper edges 61A2 and 61B2 and the lower edges 61A3 and 61B3 in the vehicle width direction to each other.

[0070] That is, when viewed from the front, the opening shape of at least a portion of the air inlet 61 is formed by the outer edges 61A1 and 61B1 in the left and right directions, the upper edges 61A2 and 61B2, and the lower edges 61A3 and 61B3.

[0071] A DRL (first lighting fixture) 41 is disposed on the outer periphery of the air intake 61. The DRL 41 is disposed on the front surface of the sides 46B and 46C. DRL is short for Daytime Running Light. The DRL 41 has a resin housing 41A, a light-emitting element (not shown) housed in the housing 41A, and a lens 41B through which light from the light-emitting element passes. The light-emitting element of the DRL 41 is, for example, composed of a light source body (not shown) and a light guide member (not shown) that guides the light from the light source body. In the DRL 41, the light-emitting element emits light, and the lens 41B appears to emit light. The light-emitting part 41C of this embodiment is constituted by the light-emitting element (not shown) and the lens 41B.

[0072] like Figure 4 As shown, the light-emitting part 41C has a pair of light-emitting parts 41D and 41E on the left and right. The light-emitting parts 41D and 41E are formed symmetrically on the left and right. When viewed from the front, the light-emitting parts 41D and 41E have: side parts 41D1 and 41E1 extending in the vertical direction, upper parts 41D2 and 41E2 extending from the upper end of the side parts 41D1 and 41E1 inward in the vehicle width direction, and lower parts 41D3 and 41E3 extending from the lower end of the side parts 41D1 and 41E1 inward in the vehicle width direction.

[0073] The side portions 41D1 and 41E1 of the light-emitting part 41C extend along the outer edges 61A1 and 61B1 of the air inlet 61 in the left and right directions, respectively. The upper portions 41D2 and 41E2 of the light-emitting part 41C extend along the upper edges 61A2 and 61B2 of the air inlet 61, respectively. The lower portions 41D3 and 41E3 of the light-emitting part 41C extend along the lower edges 61A3 and 61B3 of the air inlet 61, respectively.

[0074] In this embodiment, the lower portions 41D3 and 41E3 are positioned below the center portion 46A of the headlight bracket 46. Specifically, in this embodiment, the lower portion 41D3 on the left and the lower portion 41E3 on the right are connected below the center portion 46A to form an integral shape. The pair of light-emitting portions 41D and 41E have portions positioned below the air intake 61. In this embodiment, the light-emitting portion 41C is formed by the left light-emitting portion 41D and the right light-emitting portion 41E integrally forming a generally U-shaped structure.

[0075] The housing 41A of DRL 41 is secured to the portions of sides 46B and 46C corresponding to the outer periphery of air inlet 61 by fastening member 72. DRL 41 extends along the outer periphery of air inlet 61.

[0076] In the DRL 41 of this embodiment, when viewed from the front, the housing 41A is wider in all parts compared to the light-emitting part 41C, which extends in a roughly U-shape. The housing 41A is configured to be wider towards the rear. The housing 41A has a wall surface on the air intake 61 side that slopes towards the air intake 61 side as it moves towards the rear. As a result, the driving air from the front is guided by the housing 41A and easily drawn into the left and right air intakes 61A and 61B.

[0077] Because the DRL 41, which is easily noticeable, is arranged on most of the outer periphery of the air intake 61, the air intake 61 can be positioned at the front and made relatively inconspicuous. Therefore, the appearance of the saddle-type vehicle 10 is improved compared to the case where the air intake 61 is easily noticeable.

[0078] In addition, since the central part 46A does not have a DRL 41, there is no need to provide cutouts, fastening holes, etc. for supporting the DRL 41, which can help increase the strength of the central part 46A.

[0079] A beam lamp (second lighting fixture) 42 is disposed inside the enclosing shape of the headlight 41. The beam lamp 42 functions as both a high beam and a low beam. The beam lamp 42 is disposed on the lower side of the area enclosed by the headlight 41. The beam lamp 42 is supported on the lighting fixture support portion 46A3 of the headlight bracket 46 (see reference). Figure 3The beam lamp 42 has a light-emitting element (not shown) and a lens 42A through which light from the light-emitting element passes. The light-emitting element of the beam lamp 42 is, for example, composed of a light source body (not shown) and a reflector (not shown) that reflects light from the light source body. In the beam lamp 42, the light-emitting element emits light, and the lens 42A appears to emit light. The light-emitting section 42B of this embodiment is constituted by the light-emitting element (not shown) and the lens 42A.

[0080] A pair of air inlets 61A and 61B are formed around the beam lamp 42. Therefore, since the air inlets 61A and 61B are sandwiched between the easily noticeable DRL 41 and the beam lamp 42, they are relatively inconspicuous (not easily noticed). In particular, when the DRL 41 and beam lamp 42 are illuminated, when viewed from the front, the air inlets 61A and 61B are perforated, making it difficult for light to be reflected and easily dimmed, thus making the separation shape of the DRL 41 and beam lamp 42 easily visible. That is, the air inlets 61A and 61B are not easily noticeable.

[0081] Lens 42A has a pair of upper and lower lenses 42A1 and 42A2. Lenses 42A1 and 42A2 are formed to be relatively long laterally. Lenses 42A1 and 42A2 are convex in shape, bulging forward. In this embodiment, lenses 42A1 and 42A2 are tilted rearward from the left and right center towards the left and right sides. Therefore, when the driving wind blows from the front onto lenses 42A1 and 42A2, the driving wind is easily guided to the left and right sides of lenses 42A1 and 42A2. The convex shape of the beam lamp 42 separates the driving wind to the left and right, allowing the driving wind to easily enter the left and right air intakes 61A and 61B of the beam lamp 42.

[0082] In particular, the beam lamp 42 is positioned on the lower side of the area surrounded by the DRL 41 and at the front of the vehicle body, so that driving air can be easily drawn into the air intake 61.

[0083] The headlight 40 of this embodiment is composed of DRL 41 and beam lamp 42. The headlight 40 is disposed in front of the fork tube 34 of the front fork 14.

[0084] Figure 5 It is along Figure 4 A cross-sectional view of the VV line. The VV line corresponds to the center line of the width of the saddle-type vehicle 10. Figure 6 It is along Figure 4 A sectional view along line VI-VI.

[0085] The sides 46B and 46C of the headlight bracket 46 are formed as curved plates in the cross-sectional view, curving downwards towards the outer side in the vehicle width direction. A rear bracket (second headlight bracket) 47, which is approximately U-shaped, is supported on the left and right sides 46B and 46C. The rear bracket 47 is fixed to the sides 46B and 46C. The rear bracket 47 is fixed to the sides 46B and 46C by fastening members 73 extending in the left and right direction (see reference). Figure 2 , Figure 3 wait).

[0086] The rear support 47 has a stepped portion 47A extending in the left-right direction at its lower rear. When viewed from the side, the stepped portion 47A appears as an L-shaped groove. The bottom bridge 33 enters the stepped portion 47A from the lower rear and holds the rear support 47 in place. Therefore, the headlight support 46 is supported above the top bridge 32 by the left and right fixing portions 46A1, and below it is held to the bottom bridge 33 by the stepped portion 47A via the rear support 47.

[0087] Above the beam lamp 42 is a central portion 46A of a headlight bracket 46 that supports the DRL 41 and the beam lamp 42. The headlight bracket 46 provides stable support for the DRL 41 and the beam lamp 42 from above.

[0088] The U-shape formed by the central portion 46A and the side portions 46B and 46C of the headlight bracket 46, which opens downwards, and the U-shape formed by the rear bracket 47, which opens upwards, are combined to form a cylindrical headlight duct (intake duct) 60. The headlight duct 60 has an air inlet 61 at its front end (see reference). Figure 5 Additionally, the headlight duct 60 has a rear opening 62 at its rear end (see reference). Figure 6 The airflow enters the headlight duct 60 from the air intake 61 and exits from the rear opening 62.

[0089] The headlight duct 60 is positioned between the front forks 14, specifically between the left and right fork tubes 34. Additionally, the headlight duct 60 is positioned vertically between the top axle 32 and the bottom axle 33.

[0090] The rear opening 62 is interrupted to the left and right by the front riser 18. Behind the rear opening 62 are a pair of cylindrical rear ducts (second intake ducts) 66. The left and right rear ducts 66 extend rearward along the inner side of the left and right front frame 19 in the left-right direction. Figure 5 , Figure 6 The diagram only shows the rear pipe 66 on the left. The rear pipe 66 on the left and the rear pipe 66 on the right are symmetrical.

[0091] An air inlet 67, which widens in diameter as it moves forward, is formed at the front end of the rear duct 66 (see reference). Figure 6 The air inlets 67 are located on the left and right outer sides of the front riser 18. When viewed from the side, the air inlets 67 overlap with the front riser 18.

[0092] The rear duct 66 extends rearward at a slightly higher angle. The rear end of the rear duct 66 connects to the air filter box 68 located above it. Within the air filter box 68, the driving air flowing in from the left and right rear ducts 66 is purified. The intake path extends from the air filter box 68 to the cylinder head 24 of the power unit 12, and the intake air volume generated by the driving air is supplied to the cylinder head 24 while being adjusted by the throttle valve 69.

[0093] The saddle-riding vehicle 10 of this embodiment is a so-called uncovered type saddle-riding vehicle 10 in which the frame 11 and front fork 14 are not covered by the body cover. In such an uncovered type saddle-riding vehicle 10, it is difficult to form an airflow guide shape through the body cover, and therefore, it is difficult to efficiently guide the driving air from the front of the front fork 14 towards the frame 11 side. In addition, the headlight is likely to be positioned in front of the rear duct, and the headlight is likely to interfere with the intake of the driving air.

[0094] In contrast, in this embodiment, an air inlet 61 is formed on the front surface of the headlight 40, and a headlight duct 60 is formed by the headlight 40 and the headlight bracket 46, which can efficiently guide the driving air to the rear duct 66 on the side of the frame 11.

[0095] As explained above, according to this embodiment of the invention, as the air intake structure of a saddle-type vehicle with a headlight duct 60 arranged between the front forks 14, the headlight duct 60 has an air intake 61 that opens forward, and a DRL 41 is arranged in front of the front forks 14, extending along the outer periphery of the air intake 61. Therefore, the easily noticeable DRL 41 extends along the outer periphery of the air intake 61, thus allowing the air intake 61 to be positioned in front, and making it less noticeable while easily drawing in driving air.

[0096] In this embodiment, the DRL 41 includes a pair of light-emitting portions 41D and 41E in the vehicle width direction. When viewed from the front, the pair of light-emitting portions 41D and 41E in the vehicle width direction have at least one portion, namely the lower portion 41D3 and 41E3, disposed above and below the air intake 61. Therefore, since the DRL 41 is disposed on most of the outer periphery of the air intake 61, the air intake 61 can be positioned at the front and the air intake 61 can be made less conspicuous.

[0097] Furthermore, in this embodiment, when viewed from the front, the outer edges 61A1 and 61B1 in the left and right directions of the air intake 61 located at the outer ends in the vehicle width direction, the upper edges 61A2 and 61B2 extending from the upper ends of the outer edges 61A1 and 61B1 in the left and right directions, and the lower edges 61A3 and 61B3 extending from the lower ends of the outer edges 61A1 and 61B1 in the left and right directions, at least form a portion of the opening shape. The DRL 41 is arranged along the outer edges 61A1 and 61B1 in the left and right directions, the upper edges 61A2 and 61B2, and the lower edges 61A3 and 61B3 in the left and right directions. Therefore, since the DRL 41 is arranged on most of the outer periphery of the air intake 61, the air intake 61 can be positioned at the front and the air intake 61 is less conspicuous.

[0098] Furthermore, in this embodiment, the beam lamp 42 is located inside the enclosing shape of the DRL 41, and the air inlet 61 is located outside the beam lamp 42 in the left-right direction. Therefore, the air inlet 61 is sandwiched between the easily conspicuous DRL 41 and the beam lamp 42, thus making the air inlet 61 relatively less conspicuous.

[0099] Furthermore, in this embodiment, the beam lamp 42 has a convex shape that protrudes forward. Therefore, the convex shape of the beam lamp 42 separates the driving air in the vehicle width direction, making it easy to draw air into the air intake 61 of the beam lamp 42 in the vehicle width direction.

[0100] Furthermore, in this embodiment, the beam lamp 42 is positioned below the area surrounded by the DRL 41. Therefore, it is easy to draw driving air into the air intake 61.

[0101] Furthermore, in this embodiment, a headlight support 46 supporting the DRL 41 and the beam lamp 42 is provided above the beam lamp 42. Therefore, by supporting the DRL 41 and the beam lamp 42 from above, stable support can be achieved.

[0102] Furthermore, in this embodiment, the air intake 61 is configured such that, when viewed from the front, its width increases towards the rear. Therefore, it is easy to draw in the rear of the air intake 61 from the front end of the vehicle.

[0103] Furthermore, in this embodiment, the DRL 41 is configured such that its width increases towards the rear. This facilitates the intake of airflow into the air inlet 61.

[0104] Furthermore, in this embodiment, the headlight support 46 has a central portion 46A that supports the front fork 14 and the beam lamp 42, and the DRL 41 is not disposed in the central portion 46A. Therefore, it is possible to increase the strength of the central portion 46A.

[0105] Furthermore, the above embodiments represent one way of applying the present invention, and the present invention is not limited to the above embodiments.

[0106] In the above embodiment, the pair of light-emitting portions 41D and 41E in the vehicle width direction have a portion that is positioned below the air intake 61 when viewed from the front, but they may also be positioned above the air intake 61 instead of below it.

[0107] In the above embodiment, a structure was described in which a pair of light-emitting portions 41D and 41E in the vehicle width direction are positioned below and connected below the air intake 61 when viewed from the front. However, the pair of light-emitting portions 41D and 41E in the vehicle width direction can also be separated to the left and right. Alternatively, the pair of light-emitting portions 41D and 41E in the vehicle width direction can be connected below and above the air intake 61 to form a ring when viewed from the front. That is, when viewed from the front, the light-emitting portion 41C having the light-emitting portions 41D and 41E appears to extend around the outer periphery of the air intake 61. The light-emitting portion 41C can extend separately in the middle, or it can extend while connected.

[0108] In the above embodiments, an automatic two-wheeled vehicle 1 was described as an example of a saddle-riding vehicle, but the present invention is not limited thereto. The present invention can be applied to a three-wheeled saddle-riding vehicle with two front wheels or two rear wheels, or a saddle-riding vehicle with four or more wheels.
