As shown in fig. 4, the fuel tank cover 52 is attached to the front end side of the inner cover 120, and is disposed on the outer side of the fuel tank 29 in the vehicle width direction.

The fuel tank 29 is covered by a pair of a fuel tank cover 52 and a fuel tank cap 50.

The fuel tank cover 50 is a plate-like member that is disposed at substantially the center in the vehicle width direction and extends from substantially the center of the front surface of the fuel tank 29 to the front end of the seat 17 through the top surface. The upper portion of the fuel tank 29 is covered by the fuel tank cap 50.

The pair of fuel tank covers 52 are disposed on the left and right sides of the fuel tank cover 50, and cover the fuel tank 29 from the left and right sides. The fuel tank cover 52 covers the side surface of the fuel tank 29 from the top surface of the fuel tank 29 in the up-down direction of the vehicle body, extends to the side of the air cleaner case 40, and covers the upper side of the air cleaner case 40 from the side.

As shown in fig. 7, the fuel tank shield 52 is a plate member formed by bending the front lower edge 83, the front upper edge 81, and the upper edge 85 in a substantially L shape. The fuel tank cover 52 extends from the lower side to the upper side as seen in the vehicle width direction, extends forward, and then extends rearward, and is curved, as is the case with the intermediate plate 80. In other words, the fuel tank cover 52 is formed in a shape in which the lower side and the rear side are cut away as viewed in the vehicle width direction.

The fuel tank shield 52 is formed symmetrically across the fuel tank 29.

As shown in fig. 4 and 7, the fuel tank cover 52 includes: an outer shroud 54 forming an outer side surface of the vehicle body; and an inner shroud 56 that is located on the vehicle width direction inner side of the outer shroud 54 and covers the front surface side of the fuel tank 29.

The outer shroud 54 has a shape in which the tip protrudes in a wedge shape when viewed in the vehicle width direction. The front end of the outer shroud 54 is provided with: the tip 55, which is the top of the protruding shape, has a front upper edge 57 extending upward and rearward from the tip 55, and a front lower edge 59 extending downward and rearward from the tip 55. The front upper edge 57 and the front lower edge 59 form the front-end-side edge portion of the outer shroud 54.

As shown in fig. 1, the tip 55 extends to the left and right of the bottom beam 32. As shown in fig. 4, in the outer shroud 54, the front end upper edge 57 and the front end lower edge 59 are located on the front side of the fuel tank 29.

As shown in fig. 7, an upper surface edge 67 extending toward the vehicle width direction center side is continuous with the rear end of the front end upper edge 57. The upper surface edge 67 extends to the front end of the fuel tank cap 50. The end of the upper surface edge 67 located opposite to the end continuous with the front end upper edge 57 is continuous with the upper edge 61, which is the edge of the upper end and the rear end of the outer shroud 54. The upper edge 61 extends rearward along the fuel tank cover 50, and then extends obliquely downward to the vicinity of the front end of the seat 17.

The lower edge 63, which is the edge of the lower end of the outer shroud 54, is continuous with the rear end of the front end lower edge 59. The lower edge 63 is continuous with the lower edge 87 and extends in substantially the same direction as the lower edge 87. The lower edge 63 is formed to have a shorter length dimension than the upper edge 61.

The upper edge 61 and the lower edge 63 are connected by a curved edge 65, which is the edge on the rear side of the outer shroud 54. The bent edge 65 extends obliquely upward and forward from the rear end of the lower edge 63, extends obliquely upward and rearward, and further extends substantially horizontally rearward, thereby being connected to the lower end of the upper edge 61. The curved edge 65 extends along the front lower edge 83, the front upper edge 81, and the upper edge 85.

As shown in fig. 7, the intermediate plate 80 is provided so as to form the same side surface of the saddle-type vehicle 10 together with the outer cover 54. In detail, the extension 88 is covered by the outer shroud 54. In this case, the tip lower edge 83, the tip upper edge 81, and the upper edge 85 are in contact with the curved edge 65.

The extension 88 is covered by the outer shroud 54.

Fig. 8 is a cross-sectional view taken along line VIII-VIII in fig. 7.

As described above, since the concave portion 79 is provided at the front upper edge 81, a gap is formed between the front upper edge 81 and the bent edge 65.

Specifically, as shown in fig. 7 and 8, an exhaust port 97 formed by being surrounded by the curved edge 65 and the tip upper edge 81 is provided on the side surface of the same surface formed by the intermediate plate 80 and the outer shroud 54.

The air outlet 97 opens in the front-rear direction, and communicates the inside of the fuel tank shield 52 and the intermediate plate 80 with the outside. The air outlet 97 functions as an air outlet for discharging air that has entered the inside of the fuel tank hood 52.

In this way, in the saddle type vehicle 10, the air outlet 97 is formed by the bent edge 65 and the front end upper edge 81. In this way, in the saddle-type vehicle 10, the exhaust port 97 is formed in the long hole shape that is inclined so as to extend upward as going rearward, and therefore the exhaust port 97 can be provided so as to be inconspicuous from the outside. Therefore, in the saddle type vehicle 10, the external appearance can be improved.

As described above, in the saddle-type vehicle 10, the vehicle side surface is formed of the plurality of plate members, that is, the fuel tank hood 52, the intermediate plate 80, and the side plate 90. That is, in the saddle type vehicle 10, the exhaust port 97 is provided between the exterior members. In this way, in the saddle type vehicle 10, the exhaust port 97 having a different shape can be easily provided by replacing the intermediate plate 80 provided with the different concave portion 79.

The outer cover 54 has a shape bulging outward of the vehicle body. The outer shroud 54 includes a front upper surface 60, a front lower surface 62, a rear surface 64, and an upper surface 66 on the outer side of the vehicle body.

The front end upper surface 60 is an inclined surface that is inclined toward the center side in the vehicle width direction as approaching upward on the upper side of the front end of the outer shroud 54.

The front end lower surface 62 is an inclined surface that is inclined toward the vehicle body center side as going downward below the front end of the outer shroud 54.

The rear surface 64 is located rearward of the front upper surface 60 and the front lower surface 62, and is curved along the curved edge 65. The rear surface 64 is an inclined surface inclined from the front upper surface 60, the front lower surface 62, and the upper edge 61 toward the curved edge 65 toward the center in the vehicle width direction.

A ridge 68 is formed at a connection portion between the front upper surface 60 and the front lower surface 62, and a ridge 69 is formed at a connection portion between the front upper surface 60 and the front lower surface 62 and the rear surface 64. The ridge 68 and the ridge 69 form the top of the outer side surface of the outer shroud 54 in the vehicle width direction.

Fig. 9 is a diagram corresponding to a front view of the fuel tank shield 52.

As shown in fig. 9, the outer shroud 54 includes an upper surface 66 that covers the upper side of the fuel tank 29. The upper face 66 is continuous with the upper ends of the front and rear faces 60, 64. An upper surface edge 67 as an edge portion is arranged at the front end of the upper surface 66. An upper edge 61 as an edge portion is disposed on the vehicle width direction center side of the upper face 66. The upper edge 61 abuts the fuel cap 50. Thus, the front upper face 60 is continuous with the fuel cap 50.

As shown in fig. 4, the inner shroud 56 is provided on the front end side of the fuel tank shroud 52, and is disposed on the front side of the fuel tank 29.

As shown in fig. 9, the inner shroud 56 includes: an inflow surface portion 70 located on the front surface side of the fuel tank 29; and a connection surface 72 connecting the inflow surface 70 and the outer shroud 54.

The inflow surface 70 is disposed opposite to the front surface of the fuel tank 29. The inflow surface 70 is provided at an upper portion of the fuel tank shield 52, and a lower end of the inflow surface 70 is located above the air cleaner case 40. The inflow surface portion 70 is an inclined surface inclined rearward as going upward from below.

When the vehicle body is seen in front view, the pair of inflow surface portions 70 are disposed at a predetermined distance from each other via the fuel tank 29. The fuel tank cap 50 is located between the pair of inflow surface portions 70 and on the upper end side of the inflow surface portion 70 when the vehicle body is seen in front view.

The inflow surface portion 70 is provided with a plurality of ribs 73 formed by bulging in a rib shape from a portion recessed toward the fuel tank 29 side toward the front.

The inflow surface portion 70 is provided with a plurality of through holes 71 penetrating in the front-rear direction of the vehicle body. The inflow holes 71 are provided to the respective ribs 73. The inflow hole 71 is formed in a long hole shape extending in the vehicle width direction. In the inflow surface portion 70, a plurality of inflow holes 71 are provided on the vehicle width direction outer side so as to be aligned in the up-down direction.

The inflow surface portion 70 includes an inflow upper edge 76 located at an upper edge portion, and an inflow side edge 78 located at an outer side in the vehicle width direction.

The connecting surface 72 is formed in a curved surface shape rising forward from the inflow upper edge 76 to the inflow side edge 78.

The portion of the connecting surface 72 rising from the inflow upper edge 76 is connected to an edge portion of the fuel tank cap 50 located on the front end side and an upper surface edge 67 located at the front end of the upper surface 66.

The portion of the connecting surface 72 rising from the inflow side edge 78 is connected to the entire front end upper edge 57 and the upper portion of the front end lower edge 59.

The upper surface edge 67, the entirety of the front end upper edge 57, and the front end lower edge 59 are located outside the inflow surface 70 when the vehicle body is viewed from the front. Therefore, the connecting surface 72 is an inclined surface inclined toward the inside of the vehicle body as it approaches the inflow surface 70 from the outer shroud 54.

The coupling surface 72 is formed on the inner surface of the fuel tank cover 52 toward the center in the vehicle width direction.

Fig. 10 is a view showing the stepped portion 74 as viewed from the vehicle width direction center portion to the right.

As shown in fig. 10, a concave step 74 is provided at the front end of the connecting surface 72, and is recessed outward in the vehicle width direction. The step 74 is formed along the front end of the connecting surface 72 with a predetermined width. As shown in fig. 10, the stepped portion 74 is provided in front of the inflow surface portion 70.

As shown in fig. 9 and 10, the step 74 includes a concave surface 75 and a rising surface 77. The concave surface 75 is a portion recessed with respect to the other portion of the coupling face 72. The concave surface 75 extends in the up-down direction.

As shown in fig. 9, the width dimension of the concave surface 75 in the front-rear direction is approximately half of the shortest width dimension of the connecting surface portion 72 in the front-rear direction.

Concave surface 75 is continuous from leading upper edge 57, with leading upper edge 57 and concave trailing edge 75a forming an outer Zhou Zhouyuan of concave surface 75. In other words, the concave surface 75 is a range surrounded by the front end upper edge 57 and the concave surface rear edge 75a in the joint face 72.

The concave rear edge 75a extends substantially horizontally rearward from the tip 55 surrounded by the front upper edge 57 and the concave rear edge by a predetermined length, extends upward along the front upper edge 57, extends substantially vertically upward near the rear end of the front upper edge 57, and is continuous with the rear end of the front upper edge 57.

The rising surface 77 is a surface rising from the concave rear edge 75a toward the center side in the vehicle width direction. The rising surface 77 is formed as an inclined surface that is inclined rearward as it approaches the upper surface of the coupling surface 72 from the concave surface 75, in other words, as it approaches the vehicle body center.

As described above, the rising surface 77 rises from the concave trailing edge 75 a. Accordingly, the upper end side of the rising surface 77 extends so as to be inclined downward as it advances rearward, and the lower end side of the rising surface 77 extends so as to be inclined upward as it advances rearward. That is, the rising surface 77 is formed so as to face the inflow hole 71 at both ends in the long-term direction as viewed from the front.

As shown in fig. 2, the stepped portion 74 is disposed on the outer side in the vehicle width direction than the headlamp unit 34 and the front fork 14 in front view.

When the saddle-type vehicle 10 travels, so-called traveling wind W is generated, and a part of the traveling wind W is branched in the left-right direction and flows rearward after contacting the headlight unit 34. That is, in the saddle type vehicle 10, air flowing from the front toward the saddle type vehicle 10 flows outward in the vehicle width direction than the front fork 14 when contacting the headlamp unit 34.

The air flowing on the front surface of the head lamp unit 34 is directed toward the fuel tank shield 52. As shown in fig. 1 and 2, a step 74 is provided on the connecting surface 72, which is the inner surface of the front end of the fuel tank cover 52 facing the center in the vehicle width direction. As described above, the stepped portion 74 is disposed on the outer side in the vehicle width direction than the headlamp unit 34 and the front fork 14 in front view.

At least a part of the air flowing through the side surface of the head lamp unit 34 from the front surface of the head lamp unit 34 contacts the rising surface 77 of the stepped portion 74, and then passes over the rising surface 77 and faces the inflow surface 70.

In this way, in the saddle-type vehicle 10, the velocity of the traveling wind W toward the fuel tank shield 52 can be reduced by passing over the rising surface 77, in other words, the velocity of the air flowing into the fuel tank shield 52 can be reduced. Therefore, in the saddle type vehicle 10, the pressure inside the fuel tank shield 52 can be reduced.

The rising surface 77 is inclined rearward, and the upper and lower ends of the rising surface 77 are inclined toward the inflow hole 71 in front view. As a result, in the fuel tank shield 52, the air that passes over the stepped portion 74 in the front-rear direction can be guided to the inflow hole 71.

At least a portion of the air directed toward the inflow face 70 enters the interior of the fuel tank shield 52 from the inflow hole 71. As shown in fig. 6 and 7, the air that has entered the inside of the fuel tank hood 52 flows rearward of the vehicle body, and at least a part thereof is discharged to the outside of the fuel tank hood 52 through the air outlet 97.

In this way, in the saddle-type vehicle 10, the air that has entered the inside of the fuel tank cover 52 can be discharged to the outside, and therefore the rectifying effect of the vehicle body on the traveling wind W can be improved.

As described above, a part of the air that has entered the inside of the fuel tank hood 52 is guided to the opening 43 facing the air guide wall 122 by being in contact with the air guide wall 122, and flows into the air cleaner case 40 through the opening 43 of the intake duct 42.

The above-described embodiment illustrates an embodiment of the present invention, and can be arbitrarily modified and applied within a range not departing from the gist of the present invention.

For example, in the above-described embodiment, the intermediate plate 80 is provided separately from the side plate 90. However, the middle plate 80 and the side plate 90 may be integrally provided.

For example, the intermediate plate 80 may be formed of a plurality of members as long as the exhaust port 97 can be formed.

The horizontal, vertical, and other directions and various shapes in the above-described embodiments include so-called equivalent ranges that provide the same operational effects as those of the directions and shapes unless otherwise specified.

[ Structure supported by the above embodiment ]

The above embodiment supports the following structure.

The saddle-ride type vehicle according to the present invention is characterized in that the fuel tank cover is provided with a stepped portion on an inner surface side of a front end of the fuel tank.

According to this configuration, in the saddle-ride type vehicle, the wind speed of the traveling wind can be reduced. In this way, in the saddle-type vehicle, the pressure on the inner surface side of the fuel tank shield can be reduced.

In the saddle-type vehicle according to structure 1, at least a part of the step portion is formed within a range of a vertical width of the headlight unit when the vehicle is viewed from a side view.

According to this configuration, in the saddle-ride type vehicle, the flow velocity of wind passing through the side surface of the head lamp unit can be reduced. In this way, in the saddle-type vehicle, the pressure on the inner surface side of the fuel tank shield can be reduced.

(Configuration 3) in the saddle-type vehicle of configuration 2, the head lamp unit overlaps with the front fork in the width direction in front view.

According to this configuration, in the saddle-type vehicle, the traveling wind can be caused to flow to the outside of the front fork. In this way, in the saddle-type vehicle, the flow velocity of the traveling wind reaching the inside of the fuel tank shield can be reduced by the stepped portion.

In the saddle-type vehicle according to structure 3, the step portion is provided at a position outside the front fork in the vehicle width direction.

According to this structure, the traveling wind flowing outside the front fork is decelerated by the stepped portion. In this way, in the saddle-ride type vehicle, the flow velocity of wind passing through the side of the headlamp can be suppressed.

(Constitution 5) in the saddle-ride type vehicle according to any one of the configurations 1 to 4, a side plate is provided behind the fuel tank shield, an intermediate plate is provided between the fuel tank shield and the side plate, and an exhaust port is formed by the fuel tank shield and the intermediate plate.

According to this configuration, in the saddle-ride type vehicle, the wind direction entering the shroud can be made to flow outside, and therefore the rectifying effect can be improved. In the saddle type vehicle, since the exhaust port is provided in the adjacent portion of the exterior members, the size of the exhaust port can be changed only by replacing the panel.

(Structure 6) in the saddle-ride type vehicle of structure 5, the intermediate plate is formed in a shape composed of: a lower edge portion connected to an extension line of a lower edge of the fuel tank shield; a rising portion rising upward from the lower edge portion; a rear inclined portion extending rearward and upward from the rising portion; and a substantially horizontal portion extending substantially horizontally rearward from the rear inclined portion, the exhaust port being provided in front of the rear inclined portion.

According to this configuration, in the saddle-type vehicle, the exhaust port is formed in the inclined portion, so that the exhaust port can be formed unobtrusively in appearance.
