  FIG. 1 schematically shows an overall image of a motorcycle according to an embodiment of the present invention. The motorcycle 11 includes a vehicle body frame 12 and a vehicle body cover 13 that partially covers the vehicle body frame 12. The body frame 12 is provided with a head pipe 14, a pair of left and right main frames 15 extending rearward and downward from the head pipe 14, and spaced apart below the main frame 15 to extend rearward and downward from the head pipe 14. A pair of left and right down frames 16, a pair of left and right pivot frames 17 connected to the rear ends of the individual main frames 15 and extending downward, and a cross tube extending in the horizontal direction and connecting the left and right pivot frames 17. 18, a pair of left and right seat frames 19 extending rearward from the individual main frames 15, and a rear frame 21 disposed below the seat frames 19 and coupled to the cross tubes 18 and the seat frames 19. The rear frame 21 extends rearward upward from the cross tube 18 and supports the seat frame 19 from below.

  The main frame 15 includes, for example, a first frame 15a and a second frame 15b which are arranged at an interval vertically. The first frame 15a and the second frame 15b are formed, for example, of a pipe material having a circular cross section. The first frame 15a and the second frame 15b are connected to each other by the reinforcing members 22a, 22b. The reinforcing members 22a and 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 22c reinforces the rigidity of the assembly between the down frame 16 and the main frame 15.

  A front fork 23 is supported on the head pipe 14 to be steerable. The front fork 23 supports a front wheel WF so as to be rotatable around an axle 24. A steering handle 25 is connected to an 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 both left and right ends of the steering handle 25. The driver holds the grip when driving the motorcycle 11.

  A swing arm 28 is connected to the vehicle body frame 12 behind the vehicle so as to swing up and down around a pivot 27. A rear wheel WR is supported at a rear end of the swing arm 28 so as to be rotatable around an axle 29. An internal combustion engine unit 31 is mounted on the 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 transmitted to the rear wheels 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. Thus, a rigid structure is established by 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 sucked into the intake port of the internal combustion engine 32. Air is taken into the air cleaner 33 from a space (intake passage) below the seat rail 19.

  A fuel tank 34 is arranged above the main frame 15. An occupant 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 vehicle body cover 13 includes a tank cover 38 that covers the fuel tank 34, a side shroud 39 disposed below the tank cover 38 with a shape following the lower edge of the tank cover 38, and a front part of the fuel tank 34. A front shroud 53 (described later) that is connected to the front end of the tank cover 38 and covers the fuel tank 34 from the front is provided. A neck 41 for knee grip is defined at the rear of the tank cover 38 along the lower edge. When the driver straddles the occupant seat 35 and puts his feet on the step 36, the driver's knee can be pressed against the constriction 41 of the fuel cover 13.

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

  The side cover 43 is narrowed in the vehicle width direction as it approaches the occupant seat 35. The degree of throttling increases in the rear half compared to the front half in the vehicle longitudinal direction. Therefore, the tank cover 38 sharply narrows in the rear half of the vehicle longitudinal direction.

  A window hole 47 is formed in the side cover 43. The window hole 47 includes a peripheral wall 48 that extends toward the fuel tank 34 inward from an opening bordered by 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 plane except for the rear end in the vehicle longitudinal direction.

  The window hole 47 is closed by a lid member 49 from the inside. A logo 51 is drawn on the surface of the lid member 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 member 49 is further away from the opening on the outer surface as it goes toward the rear of the vehicle body. That is, the depth of the peripheral wall 48 of the window hole 47 increases toward the rear of the vehicle body.

  As shown in FIG. 3, the cover member 49 is formed integrally with the center cover 42 via the connecting piece 52. As shown in FIG. 4, the side cover 43 is fixed to the side shroud 39 with screws 52 at two places from the inside, and the front shroud 53 is fixed with screws 54 at two places from the outer surface of the front shroud 53. As shown in FIG. 2, the outer side 43a of the side cover 43 projects forward of the vehicle in plan view. The outer side 43a of the side cover 43 overlaps the edge of the front shroud 53 (see FIG. 4).

  As shown in FIG. 5, the front shroud 53 is connected to the front end of the tank cover 38 formed by the center cover 42 and the pair of side covers 43 and closes the front end of the tank cover 38. The front shroud 53 defines an opening 55 that communicates with a space defined between the fuel tank 34 and the tank cover 38. The front shroud 53 has an outer surface recessed toward the opening 55. The depression has a function of guiding the traveling wind toward the opening 55. The front shroud 53 is molded from, 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 forward of the vehicle as going upward in the direction of gravity.

  As shown in FIG. 6, on the front side of the window hole 47, between the edge (peripheral wall 48) of the window hole 47 and the lid member 49, there is a space defined between the fuel tank 34 and the tank cover 38. A first gap 56 communicating therewith is formed. Similarly, as shown in FIG. 7, at the rear side of the window hole 47, between the edge (peripheral wall 48) of the window hole 47 and the lid member 49, a partition is provided between the fuel tank 34 and the tank cover 48. 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. Part of the traveling wind passes through the first gap 56 to the side of the fuel tank 34 at the front side of the window hole 47. The running stability of the vehicle increases in accordance with the running wind that escapes in this manner. Since the window hole 47 is closed from the inside with the lid member 49 of the center cover 42, the space is not exposed as it is, the outer surface of the fuel tank 34 is not exposed as it is, and despite the formation of the window hole 47. Good appearance can be maintained.

  The traveling wind passing through the front first gap 56 or the outside traveling wind passes through the rear second gap 57 and enters the inside of the side cover 43, flows along the outer surface of the fuel tank 34, and flows into the rear intake passage of the vehicle body. It is guided to the vicinity (the space below the occupant 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 part of the fuel tank 34 narrows, the side surface of the fuel tank 34 can be reliably covered with the side cover 43 separated from the center cover 42. Regardless of the shape of the fuel tank 34, a space can be reliably defined 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 in the vehicle in plan view, and the upper central portion 53b of the front shroud 53 is inclined downward toward the rear of the vehicle in side view. The side cover 43 guides the traveling wind from the outside to 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 center 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 turned to the maximum, the window hole 47 of the side cover 43 can function as a relief for the steering handle 25, and there is sufficient space between the side cover 43 and the fuel tank 34. Space of size can be reserved.

  As is clear from FIG. 2, when the steering handle 25 is steered, the upper part of the front fork 23 and at least a part of the tank cover 38 overlap in plan view. When the steering handle 25 is steered, the tank cover 38 and the front shroud 53 form a clearance for the front fork 23. The front fork 23 and the tank cover 38 are collectively arranged to ensure a good appearance. Further, the formation of a clearance space for the front fork 23 formed below the tank cover 38 enables the traveling wind to be efficiently guided to the front shroud 53.

In the present embodiment, a logo 51 is drawn on the surface of the lid member 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 member 49 is formed inside the vehicle body rather than the outer surface of the tank cover 38, damage to the logo 51 from outside can be prevented.
