[0030] In a side view of the vehicle body, the middle panel 80 has a side surface shape that approximately reduces the tank shroud 60. Specifically, in a side view of the vehicle body, as it extends upward from the lower side, the middle panel 80 curves so as to extend forward and then backward. In other words, in a side view of the vehicle body, the middle panel 80 curves in a substantially J shape. The middle panel 80 has a strip-shaped middle panel main body portion 81 that curves upward and then backward in a side view of the vehicle body. On both sides in the width direction (both front and rear sides, both upper and lower sides) of the middle panel main body portion 81, fixing pieces 82 and 83 (see FIG. 5) that are recessed inward in the vehicle width direction with respect to the outer surface of the middle panel main body portion 81 and form a stepped shape are formed. The fixing pieces 82 and 83 are formed in a plate shape.

[0031] As shown in FIG. 5, a shroud co-fastening portion 81a that protrudes forward is formed at the lower part of the front end portion of the middle panel 80. Above the shroud co-fastening portion 81a, a first shroud fastening portion 84a is formed. In a side view of the vehicle body, a second shroud fastening portion 84b is formed rearward and upward of the first shroud fastening portion 84a. A third shroud fastening portion 84c is formed behind the second shroud fastening portion 84b. The second shroud fastening portion 84b and the third shroud fastening portion 84c are formed on the upper fixing piece 82 of the middle panel 80. An exhaust air recess 85 that is recessed rearward is formed between the second shroud fastening portion 84b and the first shroud fastening portion 84a. The exhaust air recess 85 extends rearward and upward in the vertical direction and extends from the fixing piece 82 to the middle panel main body portion 81 in the front-rear direction.

[0032] At the lower part of the fixing piece 83 on the rear side of the middle panel 80, a positioning hole part 86a is formed. A circular hole is formed in the positioning hole part 86a. A substantially annular grommet 87 as an elastic member is attached to the positioning hole part 86a. A position adjustment hole part 86b is formed above and behind the positioning hole part 86a. A long hole extending in the front-rear direction is formed in the position adjustment hole part 86b. The position adjustment hole part 86b is formed at the rear part of the fixing piece 83. An elliptical second grommet 88 extending in the front-rear direction is attached to the position adjustment hole part 86b.

[0033] A side panel 90 (see FIG. 4) is attached to the rear fixing piece 83 so as to cover the rear fixing piece 83 from the outside in the vehicle width direction. As shown in FIG. 4, the side panel 90 extends in the front-rear direction in a side view of the vehicle body. The side panel 90 has a front upper edge 91a that curves upward from the rear edge of the middle panel main body 81 and then curves backward.

[0034] A rear upper edge 91b extending along the front edge 17a and the lower edge 17b of the seat 17 is formed at the rear end (one end) of the front upper edge 91a. On the other hand, a front lower edge 91c that extends rearward and downward from the lower end (the other end) of the front upper edge 91a and then gently extends rearward and upward is formed at the lower end of the front upper edge 91a. A rear edge 91d extending rearward and upward from the front lower edge 91c is formed between the rear upper edge 91b and the front lower edge 91c. The connection part between the rear edge 91d and the front lower edge 91c has an edge shape that is notched upward. That is, a notch 92 is formed at the connection part between the rear edge 91d and the front lower edge 91c.

[0035] By making the exterior panel 70 have a split structure of the middle panel 80 and the side panel 90, each part of the exterior panel 70 can be miniaturized and the handling performance can be improved. Also, for example, by making it possible to select an optional middle panel or side panel, it becomes possible to replace only a part of the exterior panel 70, and it is easy to improve the degree of freedom in appearance. Furthermore, since it is possible to replace only a part of the exterior panel 70, it is easy to suppress the replacement cost during maintenance.

[0036] A side cover 100 is disposed at the lower rear of the exterior panel 70. The side cover 100 has a substantially L-shaped bent configuration when viewed from the side of the vehicle body. As shown in FIG. 5, the side cover 100 has a front portion 101 that overlaps with the main frame 19a (see FIG. 2), and a rear portion 102 that extends rearward and upward from the lower rear end of the front portion 101 so as to overlap with the rear sub-frame 20b (see FIG. 2).

The inner surface part 121a and the front and rear wall parts 121b and 121c form the stay part 121 having a substantially U-shaped cross section.

[0051] At the base end of the stay part 121, a side fastening part 122a is formed. At the tip end of the stay part 121, a cylindrical side fastening part 122b is formed. The side fastening part 122b overlaps with the main frame 19a in a side view of the vehicle body (see FIG. 6). At both longitudinal ends of the inner surface part 121a of the stay part 121, stay co-fastening parts 123a and 123b having holes that penetrate the inner surface part 121a in the thickness direction are provided. At the lower part of the rear wall part 121b of the stay part 121, a pipe passing part 124a that is notched in a concave shape toward the inner side in the vehicle width direction is formed.

[0052] Here, as shown in FIG. 6, in the inner cover 110, the box fastening portion 112a is fastened to the cover fastening portion 30a (see FIG. 2) of the air cleaner box 30. Also, the cover fastening piece 116a is fastened to the cover fastening portion 29d of the fuel tank 29 together with the tank cap cover 45. Further, the frame fastening portion 117a is fastened to the center frame 19c. Also, the frame fastening portion 117b is fastened to the seat frame 20a. Further, the cover fastening portion 118a is fastened to the rear cover 36. Note that the seat covering portion 111c is covered from above by the seat 17. Thus, the inner cover 110 is supported by the vehicle body so as to cover the lower portion of the fuel tank 29 and the air cleaner box 30 from the outside in the vehicle width direction.

[0053] At this time, as shown in FIG. 6, a reservoir tank stay 130 is supported by the stay portion 121 of the inner cover 110. The reservoir tank stay 130 is a metal plate extending along the stay portion 121. The reservoir tank stay 130 is formed to be narrower in width than the inner surface portion 121a of the stay portion 121. Fastening portions 131 and 132 are formed above and below the reservoir tank stay 130. A reservoir mounting portion 133 is formed between the pair of upper and lower fastening portions 131 and 132.

[0054] The reservoir tank stay 130 has the pair of upper and lower fastening portions 131 and 132 fastened to the rear sub-frame 20b together with the stay co-fastening portions 123a and 123b (see FIG. 7) of the inner cover 110. That is, the reservoir tank stay 130 is co-fastened and fixed to the rear sub-frame 20b together with the stay portion 121 of the inner cover 110.

[0055] A reservoir tank 39 is attached to a reservoir attachment portion 133 of a reservoir tank stay 130. The reservoir tank 39 is fixed to the reservoir tank stay 130 by an axially-shaped fixing member extending in the vehicle width direction. As a result, the reservoir tank 39 is disposed in a state of entering a reservoir avoiding portion 119 between a stay portion 121 and an inner main body portion 111. A brake fluid pipe 40 extending from the reservoir tank 39 is disposed across the stay portion 121 in the vehicle width direction outside the stay portion 121. The brake fluid pipe 40 extends rearward of the stay portion 121 through a pipe passage portion 124a of the stay portion 121. The brake fluid pipe 40 is connected to a lower master cylinder (not shown) for brakes.

[0056] FIG. 10 is a perspective view of an assembled structure of a tank shroud 60, an exterior panel 70, a side cover 100, an inner cover 110, and a reservoir tank 39 as viewed from the inner side in the vehicle width direction. In the saddle-riding type vehicle 10 of the present embodiment, a tank shroud 60, an exterior panel 70, and a side cover 100 are attached to an inner cover 110. Specifically, the tank shroud 60 and a middle panel 80 of the exterior panel 70 are integrated and attached to the inner cover 110. That is, the middle panel 80 of the exterior panel 70 is pre-attached to the inner surface of the tank shroud 60. Fastening members are inserted into shroud fastening portions 84a to 84c of the middle panel 80 from the inner surface in the vehicle width direction, and these fastening members are fastened to the tank shroud 60. Thereby, the tank shroud 60 and the middle panel 80 are integrated.

[0057] Similarly, the side cover 100 and a side panel 90 of the exterior panel 70 are integrated and attached to the inner cover 110. That is, the side panel 90 of the exterior panel 70 is pre-attached to the inner surface of the side cover 100. Fastening members are inserted into panel fastening pieces 103a to 103c of the side cover 100 from the inner surface in the vehicle width direction, and these fastening members are fastened to the side panel 90. Thereby, the side cover 100 and the side panel 90 are integrated.

[0058] In the integrated tank shroud 60 and middle panel 80, the claw portions 65a, 65b (see FIGS. 4 and 10) formed at the front inner surface of the tank shroud 60 are engaged with the shroud engagement holes 53a, 53b (see FIG. 2) at the front end of the tank front cover 50. Further, the insertion claw portion 67a (see FIGS. 4 and 5) formed at the rear inner surface of the tank shroud 60 is inserted into and engaged with the shroud engagement portion 113b of the inner cover 110. Also, the insertion claw portions 89a, 89b, 89c (see FIG. 10) on the inner surface of the middle panel 80 are inserted into and engaged with the middle engagement portions 114a, 114b, 114c of the inner cover 110. Thereby, the integrated tank shroud 60 and middle panel 80 are temporarily fixed to the inner cover 110.

[0059] Then, the tank shroud 60 is fastened to the upper and lower fastening portions 54a, 54b (see FIG. 2) of the tank front cover 50 by the fastened portions 66a, 66b (see FIG. 10) at the front inner end of the tank shroud 60. Also, on the outer surface of the tank shroud 60, the front fastening portion 64a is fastened together with the shroud co-fastening portion 81a of the middle panel 80 to the shroud co-fastening portion 113a of the inner cover 110. Further, the tank shroud 60 is fastened to the tank cap cover 45 by the rear fastening portion 64b. Thereby, the tank shroud 60 and middle panel 80 are fixed to the vehicle body in a state of being attached to the inner cover 110. At this time, the front fixing piece 82 of the middle panel 80 is covered by the tank shroud 60. At this time, the exhaust recess 85 forms an opening shape together with the tank shroud 60 and functions as an exhaust port for exhausting the running wind that has entered the inside of the tank shroud 60.

[0060] In the integrated side panel 90 and side cover 100, insertion portions 94a and 94b (see FIG. 4) on the inner surface of the side panel 90 are respectively inserted into the positioning hole portion 86a (see FIG. 4) and the position adjustment hole portion 86b (see FIG. 4) of the middle panel 80. The insertion portions 94a and 94b protrude inward in the vehicle width direction from the inner surface of the side panel 90 and have a shape with a bulged tip. The front insertion portion 94a is inserted into the circular grommet 87 of the positioning hole portion 86a, and the bulged shape at the tip forms a temporary anti-disengagement state. Similarly, the rear insertion portion 94b is inserted into the elliptical second grommet 88 of the position adjustment hole portion 86b, and the bulged shape at the tip forms a temporary anti-disengagement state. Thereby, the integrated side panel 90 and side cover 100 are temporarily fixed to the inner cover 110 via the middle panel 80.

[0061] Here, the tip (inner end) of the front insertion portion 94a can abut against the circular insertion recess 115a of the inner cover 110. Therefore, by abutting the tip of the insertion portion 94a against the insertion recess 115a of the inner cover 110, it is positioned with respect to the inner cover 110. On the other hand, the rear insertion portion 94b is inserted into the elliptical second grommet 88 of the position adjustment hole portion 86b and can penetrate the insertion opening 115b of the inner cover 110. Therefore, even if there is a shape error in the side panel 90, such as a shape error in the distance between the front and rear insertion portions 94a and 94b, the rear insertion portion 94b is mounted in a state of moving within the elliptical second grommet 88. Therefore, it is easier to engage the side panel 90 with the middle panel 80 by absorbing the shape error.

[0062] The fastening portions 104a and 104b of the side cover 100 are fastened to the side fastening portions 122a and 122b of the inner cover 110. Thereby, the side panel 90 and the side cover 100 are fixed to the vehicle body in a state of being attached to the inner cover 110.

[0063] Therefore, in the present embodiment, by integrally providing the inner cover 110 with the inner main body portion 111 and the stay portion 121, the tank shroud 60, the exterior panel 70, and the side cover 100 that form the outer side surface of the vehicle body can be attached to the vehicle body starting from a single inner cover 110. Thus, even in a configuration having a plurality of exterior covers, the shape error between the covers can be made less noticeable.

[0064] In the present embodiment, when the tank shroud 60, the exterior panel 70, and the side cover 100 are attached to the inner cover 110, the reservoir tank 39 is covered by the exterior panel 70 and the side cover 100 as shown in FIG. 4. In the present embodiment, the reservoir tank 39 overlaps with the boundary portion between the exterior panel 70 and the side cover 100 when viewed from the side of the vehicle body. Specifically, the reservoir tank 39 overlaps with the boundary portion formed by the front lower edge 91c and the rear lower edge 91d of the side panel 90 in the exterior panel 70 and the upper edge 101a and the rear upper edge 102a of the side cover 100 when viewed from the side of the vehicle body. A notch 92 is formed in the side panel 90, and an opening-shaped window 99 surrounded by the notch 92, the upper edge 101a, and the rear upper edge 102a of the side cover 100 is formed. Through the window 99, the reservoir tank 39 is exposed to the outside in the vehicle width direction. In the present embodiment, when viewed from the side of the vehicle body, the lower limit portion 39b of the reservoir tank 39 is located inside the window 99, and the upper portion of the lower limit portion 39b is visible from the outside in the vehicle width direction through the window 99 (see FIG. 4).

[0065] FIG. 11 is a cross-sectional view taken along line XI-XI in FIG. 4. FIG. 12 is a cross-sectional view taken along line XII-XII in FIG. 4. The reservoir tank 39 is arranged in a state of entering the reservoir avoidance part 119 of the inner cover 110 when viewed from the front. The left part (the inner part in the vehicle width direction) of the reservoir tank 39 is arranged in a state of entering between the inner lower part 111a of the inner cover 110 and the stay part 121 when viewed from the front. The reservoir tank 39 is arranged such that the thickness center (the center of the left - right width) 39L intersects the inner cover 110. That is, the reservoir tank 39 is arranged in a state of being biased outward in the vehicle width direction with respect to the inner cover 110. The space generated between the inner cover 110 and the side cover 100 on the outer side in the vehicle width direction thereof can be effectively utilized as the arrangement space of the reservoir tank 39. Further, by arranging the reservoir tank 39 to be biased outward in the vehicle width direction with respect to the inner cover 110, the space inside the inner cover 110 in the vehicle width direction can be more easily utilized as the arrangement space for other components. In the present embodiment, an electrical component 140 to which an electrical harness is connected is arranged on the inner side in the vehicle width direction of the reservoir tank 39. The reservoir tank 39 is arranged on the outer side in the vehicle width direction than the vehicle body frame 11, and it is easier for an operator to access from the outer side in the vehicle width direction.

[0066] As described above, according to the present embodiment to which the present invention is applied, in the saddle - type vehicle 10 including the fuel tank 29 arranged above the main frame 19a, the reservoir tank 39 arranged below the fuel tank 29, the reservoir tank stay 130 that supports the reservoir tank 39, the inner cover 110 arranged on the side of the main frame 19a and the fuel tank 29, the tank shroud 60 that covers the inner cover 110 from the side, and the side cover 100 that covers the reservoir tank stay 130 from the side, an exterior panel 70 is arranged between the tank shroud 60 and the side cover 100. The inner cover 110 overlaps the rear sub - frame 20b from the outer side in the vehicle width direction when viewed from the side of the vehicle body, and is clamped together with the reservoir tank stay 130 to the rear sub - frame 20b. The tank shroud 60, the exterior panel 70, and the side cover 100 are attached to the inner cover 110.

[0067] According to this configuration, since the reservoir tank stay 130 is attached to the inner cover 110 located outside the vehicle width direction from the rear sub-frame 20b, the reservoir tank stay 130 is likely to be arranged outside the vehicle width direction from the rear sub-frame 20b. Therefore, it is easy to access the reservoir tank 39 supported by the reservoir tank stay 130 from the outside in the vehicle width direction. Further, since the inner cover 110 has a shape that is clamped together with the reservoir tank stay 130, a configuration can be adopted in which the side cover 100 covering the reservoir tank stay 130 is attached to the inner cover 110.

[0068] Therefore, even when the saddle-type vehicle 10 uses a lot of exterior covers such as the tank shroud 60, the exterior panel 70, and the side cover 100, the attachment locations can be aggregated into a part of the inner cover 110. Therefore, based on the inner cover 110, the positioning of each exterior cover can be performed to suppress the cumulative tolerance of the exterior covers. Therefore, it is difficult to impair the design such as a gap due to misalignment between the exterior covers after attachment. Further, even when the exterior cover is changed to an optional part by customization or the like, the attachment location can be aggregated into a part of the inner cover 110, so that the replacement work can be facilitated. Furthermore, the inner cover 110 has an integral stay portion 112, and while hiding the welding marks and fastening locations of the rear sub-frame 20b, it is clamped together with the reservoir tank stay 130 as another part to the rear sub-frame 20b. Therefore, it is possible to achieve both an improvement in assemblability due to a reduction in the number of parts and an improvement in design as compared with the case where the stay portion 112 is a separate body. From the above, in the present embodiment, it is possible to provide the saddle-type vehicle 10 that can easily improve the appearance while ensuring the accessibility to the reservoir tank 39.

[0069] In the present embodiment, the reservoir tank stay 130 is arranged between the inner cover 110 and the side cover 100 in the vehicle width direction. According to this configuration, since the reservoir tank stay 130 is disposed between the inner cover 110 and the side cover 100, the space between the inner cover 110 and the side cover 100 can be effectively utilized as the equipment mounting space for the reservoir tank stay 130, and the degree of freedom in the layout of the saddle-type vehicle 10 can be improved.

[0070] Further, in the present embodiment, a reservoir tank 39 supported by the reservoir tank stay 130 is provided, and at least a part of the reservoir tank 39 is disposed between the inner cover 110 and the exterior panel 70 in the vehicle body width direction. According to this configuration, since at least a part of the reservoir tank 39 is disposed between the inner cover 110 and the side cover 100, the space between the inner cover 110 and the side cover 100 can be effectively utilized as the equipment mounting space for the reservoir tank 39, and the degree of freedom in the layout of the saddle-type vehicle 10 can be improved.

[0071] Further, in the present embodiment, a window 99 for visually recognizing the liquid level in the reservoir tank 39 is formed by the side cover 100 and the exterior panel 70. According to this configuration, since the window 99 for visually recognizing the liquid level in the reservoir tank 39 is formed in the exterior cover, even in a configuration where the reservoir tank 39 is covered by the exterior cover, the liquid level can be easily confirmed, and the maintainability can be improved.

[0072] Further, in the present embodiment, the window 99 is a notch 92 formed in the side panel 90 of the exterior panel 70 and separated from the side cover 100 at the edges 91c, 91d, 101a, 102a where the side panel 90 of the exterior panel 70 and the side cover 100 are adjacent to each other in a side view of the vehicle body. According to this configuration, the window 99 can be easily configured by providing the notches 92 at the edges 91c, 91d of the side panel 90 of the exterior panel 70.

[0073] In addition, in the present embodiment, the exterior panel 70 is composed of a middle panel 80 that engages with the tank shroud 60 and a side panel 90 that is disposed behind the middle panel 80. According to this configuration, since the exterior panel 70 is disposed between the front tank shroud 60 and the rear side cover 100, it is likely to be conspicuous when viewed from the side of the vehicle body. However, by configuring the exterior panel 70 with a plurality of panels including the middle panel 80 and the side panel 90, an improvement in appearance can be expected.

[0074] [Other Embodiments] The above-described embodiments merely show one aspect of the present invention, and can be arbitrarily modified and applied without departing from the gist of the present invention.

[0075] In the above embodiment, the exterior panel 70 has a middle panel 80 and a side panel 90, and a structure that is divided into two parts front and rear has been described, but it is not limited to this. For example, the exterior panel 70 may have a shape in which the middle panel 80 and the side panel 90 are integrated, and the positioning hole portions 85a and the position adjustment hole portions 85b between the middle panel 80 and the side panel 90 may be omitted.
