22a, 22b reinforce the rigidity of the assembly of the first frame 15a and the second frame 15b. Similarly, the down frame 16 and the second frame 15b are mutually connected by the reinforcing member 22c. The reinforcing member 22 c reinforces the rigidity of the assembly between the down frame 16 and the main frame 15.

A front fork 23 is supported by the head pipe 14 in a steerable manner. The front fork 23 supports a front wheel WF rotatably around an axle 24. A steering handle 25 is coupled to the upper end of the front fork 23. A headlight device 26 is fixed to the steering handle 25 in front of the head pipe 14. Grips are fixed to the left and right ends of the steering handle 25. The driver grips the grip when driving the motorcycle 11.

A swing arm 28 is connected to the vehicle body frame 12 at the rear of the vehicle so as to be swingable up and down around a pivot 27. A rear wheel WR is supported rotatably around an axle 29 at the rear end of the swing arm 28. An internal combustion engine unit 31 is mounted on the vehicle body frame 12 between the front wheel WF and the rear wheel WR. The internal combustion engine unit 31 includes an internal combustion engine 32 that generates a driving force to be transmitted to the rear wheel WR.

The lower end of the main frame 15 is connected to the rear side of the internal combustion engine 32, and the lower end of the down frame 16 is connected to the front side of the internal combustion engine 32. A rigid structure is thus established in the internal combustion engine 32 in addition to the main frame 15 and the down frame 16. The down frame 16 functions as a so-called engine hanger. The pivot 27 is supported by the pivot frame 17.

An air cleaner 33 is connected to the internal combustion engine 32. The air cleaner 33 removes dust from the air drawn into the intake port of the internal combustion engine 32. Air is taken into the air cleaner 33 from the space (intake passage) below the seat rail 19.

A fuel tank 34 is disposed above the main frame 15. An occupant's seat 35 is mounted on the seat frame 19 behind the fuel tank 34. A step 36 is attached to the pivot frame 17 below the pivot 27.

The body cover 13 has a tank cover 38 covering the fuel tank 34, a side shroud 39 provided with a shape following the lower edge of the tank cover 38 and disposed below the tank cover 38, and in front of the fuel tank 34 And a front shroud 53 (described later) that is coupled to the front end of the tank cover 38 and covers the fuel tank 34 from the front. A knee grip neck 41 is defined along the lower edge at the rear of the tank cover 38. When the driver straddles the passenger seat 35 and steps on the step 36, the driver's knee can be pressed against the waist 41 of the fuel cover 13.

As shown in FIG. 2, the tank cover 38 is provided with a center cover 42 covering the center of the fuel tank 34 from the front side to the rear side, and is disposed on the left and right sides of the center cover 42. And a pair of side covers 43 covering side portions of the fuel tank 34 while forming a space therebetween. The center cover 42 and the side cover 43 are each molded, for example, from a resin material. The center cover 42 is screwed to the front shroud 53 at two points on the front end, and screwed to the fuel tank 34 behind the filler cap 45.

The side cover 43 is squeezed in the vehicle width direction as it approaches the passenger seat 35. The degree of throttling is enhanced in the rear half as compared to the front half in the front-rear direction of the vehicle body. Therefore, the tank cover 38 narrows sharply at the rear half of the vehicle body in the front-rear direction.

A window hole 47 is formed in the side cover 43. The window hole 47 includes a peripheral wall 48 extending toward the fuel tank 34 from the opening edged on the outer surface of the side cover 43. The peripheral wall 48 is formed of a curved surface having a generatrix parallel to the horizontal surface except for the rear end in the vehicle longitudinal direction.

The window hole 47 is closed by a lid 49 from the inside. A logo 51 is drawn on the surface of the lid 49 in the window hole 47. The logo 51 may be drawn on the surface of the lid 49 with a decorative material such as paint, or may be molded with a decorative material such as metal or resin and attached to the surface of the lid 49. The lid 49 moves away from the opening on the outer surface as it goes to the rear of the vehicle body. That is, the depth of the peripheral wall 48 of the window hole 47 increases as it goes to the rear of the vehicle body.

As shown in FIG. 3, the lid 49 is integrally formed with the center cover 42 via the connection piece 52. As shown in FIG. 4, the side cover 43 is screwed to the side shroud 39 from the inside at two positions, and is screwed to the front shroud 53 from the outer surface of the front shroud 53 at two positions. As shown in FIG. 2, the outer side 43 a of the side cover 43 protrudes forward of the vehicle in a plan view. The outer side 43a of the side cover 43 is superimposed on the edge of the front shroud 53 (see FIG. 4).

As shown in FIG. 5, the front shroud 53 is coupled to the front end of the tank cover 38 formed by the center cover 42 and the pair of side covers 43 to close the front end of the tank cover 38. The front shroud 53 defines an opening 55 communicating with a space defined between the fuel tank 34 and the tank cover 38. The forward shroud 53 has an outer surface recessed toward the opening 55. The recess has a function of guiding the traveling wind toward the opening 55. The front shroud 53 is molded of, for example, a resin material. As shown in FIG. 4, the upper central portion 53b of the front shroud 53 is inclined forward of the vehicle in a side view. The upper central portion 53b is displaced toward the front of the vehicle as it goes upward in the direction of gravity.

As shown in FIG. 6, on the front side of the window 47, in the space defined between the fuel tank 34 and the tank cover 38, between the edge (peripheral wall 48) of the window 47 and the lid 49. A first gap 56 is formed to communicate with it. Similarly, as shown in FIG. 7, between the fuel tank 34 and the tank cover 48 between the edge (peripheral wall 48) of the window hole 47 and the lid 49 on the rear side of the window hole 47 A second gap 57 communicating with the space to be formed is formed.

Next, the operation of the present embodiment will be described. As shown in FIG. 8, the traveling wind is taken into the space from the opening 55 of the front shroud 53 and flows along the fuel tank 34. The fuel tank 34 is cooled by the traveling wind. A portion of the traveling wind escapes from the first gap 56 to the side of the fuel tank 34 on the front side of the window hole 47. The running stability of the vehicle is enhanced according to the running wind which is thus released. Since the window hole 47 is closed from the inside by the lid 49 of the center cover 42, the space is not exposed as it is and the outer surface of the fuel tank 34 is not exposed as it is, regardless of the formation of the window hole 47. Good appearance can be maintained.

The traveling wind passing through the first gap 56 on the front side and the traveling wind outside pass through the second gap 57 on the rear side and enter the inside of the side cover 43 and flow along the outer surface of the fuel tank 34 and the intake passage behind the vehicle body It is led to the vicinity (a space below the passenger seat 35). The drivability of the motorcycle 11 is improved.

The tank cover 38 according to the present embodiment includes a center cover 42 and a side cover 43. The side cover 43 can be separated from the center cover 42. Therefore, even if the lower side of the fuel tank 34 is depressed, the side cover 43 separated from the center cover 42 can reliably cover the side surface of the fuel tank 34. Regardless of the shape of the fuel tank 34, a space can be reliably partitioned between the tank cover 38 and the fuel tank 34.

In the present embodiment, the outer side 43a of the side cover 43 projects forward of the vehicle in a plan view, and the upper central portion 53b of the front shroud 53 is inclined downward toward the rear of the vehicle in a side view. The side cover 43 guides the traveling wind from the outside toward the inside. The front shroud 53 guides the traveling wind from the upper side to the lower side. Thus, the traveling wind is collected toward the opening 55 of the front shroud 53. Intake performance is improved.

As shown in FIG. 4, the steering handle 25 is steered around the central axis Xis of the head pipe 14. In the present embodiment, the window hole 47 of the side cover 43 is provided at a position corresponding to the grip of the steering handle 25 when the steering handle 25 is turned. The window hole 47 of the side cover 43 is located on the movement path of the steering handle 25. Therefore, even if the steering handle 25 is steered to the maximum, the window hole 47 of the side cover 43 can function as a relief of the steering handle 25 and sufficient space between the side cover 43 and the fuel tank 34 Space of size can be secured.

As apparent from FIG. 2, when the steering handle 25 is turned, the upper portion of the front fork 23 and at least a part of the tank cover 38 overlap in a plan view. When the steering handle 25 is steered, the tank cover 38 and the front shroud 53 form a relief for the front fork 23. The front fork 23 and the tank cover 38 are arranged together to ensure a good appearance. In addition, the formation of a space for relief of the front fork 23 formed below the tank cover 38 makes it possible to efficiently guide the traveling wind to the front shroud 53.

In the present embodiment, a logo 51 is drawn on the surface of the lid 49 in the window hole 47. Since the logo 51 is surrounded by the edge of the window hole 47, the logo 51 is emphasized and a good appearance is realized. Since the lid 49 is formed on the inner side of the vehicle body than the outer surface of the tank cover 38, damage to the logo 51 from the outside can also be prevented.
