The cylinder portion 42 of the engine 36 includes a cylinder bore (not shown) into which a piston (not shown) is inserted, and an axis 42a of the cylinder bore is tilted forward. That is, the cylinder portion 42 tilts forward.

The intake device 51 includes: a throttle body 81 connected to a connection portion 47a provided on the rear surface of the cylinder head 47; and an air cleaner 83 connected to the throttle body 81 through a connection pipe 82. The air cleaner 83 is disposed in a space 84 surrounded by the main frame 22, the seat frame 24, and the sub-frame 26 in a side view.

The fuel tank 61 includes an outer plate 86 forming an outer side and a bottom plate 87 joined to an inner side of the outer plate 86. The front portion of the fuel tank 61 is attached to the reinforcement plate 28, and the rear portion of the fuel tank 61 is attached to the cross member 24a (the seat frame 24 erected on the left and right sides).

A fuel fill port 88 is provided in an upper portion of the outer plate 86, and the fuel fill port 88 is closed by a cap 89. The bottom plate 87 is curved so as to protrude upward and has a concave portion. The main frame 22 passes below the floor 87.

A flange portion 61a is formed by joining a peripheral edge portion of the outer panel 86 to a peripheral edge portion of the bottom plate 87, and lowermost portions 61b (portions indicated by black circles) located on both left and right sides of the lowermost portion of the flange portion 61a are disposed between the main frame 22 and the cylinder portion 42 (specifically, the cylinder head cover 48) in a side view.

A fuel pump 91 that supplies fuel in the fuel tank 61 to the intake device 51 of the engine 36 is disposed below the main frame 22 and above the cylinder portion 42 of the engine 36.

The fuel pump 91 includes: a pump main body that sucks and discharges fuel; an electric motor that drives the pump main body; and a fuel filter for filtering the sucked fuel, wherein the whole fuel pump 91 is covered by the casing.

The longitudinal direction of the fuel pump 91 coincides or substantially coincides with the vehicle width direction.

The fuel pump 91 is disposed behind the reinforcing plate 28 above the lowest portion 61b of the fuel tank 61. The fuel pump 91 is disposed above the lowermost portion 61b of the fuel tank 61 in side view.

That is, the fuel pump 91 is covered by the fuel tank 61 from above and from both the left and right. Therefore, the fuel pump 91 is not visible from the side, and the appearance of the motorcycle 10 can be improved.

Further, the fuel pump 91 is disposed in a relatively large space 93 surrounded by the main frame 22, the lower frame 27, the reinforcement plate 28, and the cylinder portion 42 (specifically, the cylinder head cover 48) in a side view. By tilting the cylinder portion 42 forward, the space 93 is further increased.

The main frame 22 includes a bent portion 22a protruding upward in the middle, and left and right seat frames 24 are connected to the bent portion 22 a.

A tank 95 for temporarily storing the evaporated fuel in the fuel tank 61 and sending the evaporated fuel to the intake device 51 is disposed above the coupling portion 29 where the main frame 22 and the left and right seat frames 24 are coupled.

The canister 95 is located below the rear portion of the fuel tank 61, is formed in a cylindrical shape extending in the longitudinal direction in the front-rear direction with a high front and a low rear, and is covered with the fuel tank 61 from above and from both sides.

A space 94 recessed in a triangular shape is formed above the coupling portion 29, and a part of the tank 95 is disposed in the space 94. This enables the canister 95 to be disposed further downward, the floor plate 87 of the fuel tank 61 to be disposed at a lower position, and the capacity of the fuel tank 61 to be increased.

A charging pipe 96 and a cleaning pipe 97 are connected to a cylindrical front end surface 95a of the tank 95, and a fresh air introduction pipe 98 and a drain pipe 99 are connected to a cylindrical rear end surface 95b of the tank 95.

The filler pipe 96 extends to the filler opening 88 (see fig. 2) of the fuel tank 61, and introduces the evaporated fuel in the fuel tank 61 into the canister 95. The cleaning pipe 97 extends to the intake device 51 (more specifically, the throttle body 81) of the engine 36, and guides the evaporated fuel adsorbed on the activated carbon in the canister 95 to the intake device 51.

The fresh air introducing pipe 98 is a pipe: the rear end surface of the tank 95 extends rearward along the seat frame 24 between the left and right seat frames 24, and fresh air is introduced into the tank 95 from the open rear end portion. By sucking fresh air into the canister 95, the evaporated fuel can be released from the activated carbon and supplied to the air intake device 51.

The drain pipe 99 is a pipe for discharging liquid such as moisture stored in the tank 95 to the outside, and the drain pipe 99 extends downward from the rear end surface 95b of the tank 95 along the rear portion of the main frame 22 and discharges the liquid from the open lower end portion.

As described above, the canister 95 of the motorcycle 10 (see fig. 1) is disposed below the fuel tank 61 above the main frame 22, is connected to the fuel tank 61, and temporarily stores evaporated fuel generated from the fuel tank 61. The tank 95 is covered with the fuel tank 61 from above and from the side.

With this configuration, by covering the canister 95 with the fuel tank 61, the canister 95 can be protected by the fuel tank 61, and the appearance can be improved. Further, since the tank 95 is disposed above the main frame 22, the tank 95 can be protected from below by the main frame 22. Further, both the fuel pump 91 and the tank 95 can be disposed in a concentrated manner and covered with the fuel tank 61, and the length of the pipe or the like connected to the fuel pump 91 and the tank 95 can be shortened.

Fig. 3 is an enlarged view of a main portion of fig. 2.

The fuel pump 91 is disposed forward of the uppermost upper end portion of the forward tilting cylinder portion 42 (specifically, the head cover 48), that is, the uppermost portion 48a (indicated by a black circle) and above a horizontal line 100 passing through the uppermost portion 48a in a side view.

Thus, the fuel pump 91 is disposed between the forward-inclined cylinder portion 42 and the reinforcement plate 28 connecting the front end portions of the main frame 22 and the lower frame 27, respectively. Accordingly, a relatively large space 93 can be secured between the cylinder head 47 and the reinforcing plate 28, and the fuel pump 91 can be arranged compactly while increasing the degree of freedom of arrangement.

In the reinforcement plate 28, a rear end edge 28a on the side facing the cylinder portion 42 is curved so as to project toward the vehicle front. Thus, by bending the rear end edge 28a of the reinforcing plate 28, the space 93 can be secured to a larger extent, and the degree of freedom in the arrangement of the fuel pump 91 can be increased.

The fuel pump 91 is mounted to the reinforcing plate 28 by a pump mounting bracket 102. The pump mounting bracket 102 is fastened to the reinforcement plate 28 by a pair of bolts 103.

A fuel injection valve 105 is attached to an upper portion of the throttle body 81 near the cylinder portion 42, and the fuel injection valve 105 injects fuel into a combustion chamber in the cylinder portion 42 through an intake port of the cylinder head 47.

The fuel pump 91 is provided with an introduction pipe connection port 91a, a supply pipe connection port 91b, and a return pipe connection port 91c, the introduction pipe connection port 91a is connected to an introduction pipe 107, the supply pipe connection port 91b is connected to a supply pipe 108, and the return pipe connection port 91c is connected to a return pipe 109.

The introduction pipe 107 introduces fuel from the fuel tank 61 (see fig. 2) to the fuel pump 91. The supply pipe 108 supplies fuel from the fuel pump 91 to the fuel injection valves 105. The return pipe 109 returns surplus fuel to the fuel tank 61 when the fuel is introduced from the fuel tank 61 to the fuel pump 91 through the introduction pipe 107.

By disposing the fuel pump 91 in the space 93, the fuel pump 91 can be disposed in the vicinity of the fuel tank 61 and the fuel injection valve 105. Therefore, the length of the pipe from the fuel pump 91 to the introduction pipe 107 and the return pipe 109 of the fuel tank 61 and the length of the pipe from the fuel pump 91 to the supply pipe 108 of the fuel injection valve 105 can be shortened, and the cost can be reduced.

As described above, the lower frame 27 extends rearward and downward below the main frame 22 from the front seat pipe 21, the main frame 22 and the lower frame 27 are coupled by the reinforcement plate 28, and the fuel pump 91 is disposed rearward of the reinforcement plate 28.

According to this structure, the fuel pump 91 can be protected from the vehicle front side by the reinforcement plate 28.

Further, a pump mounting bracket 102 is provided on the main frame 22 or the reinforcement plate 28, and the fuel pump 91 is mounted on the pump mounting bracket 102.

According to this structure, the fuel pump 91 can be firmly supported by the high-rigidity reinforcing plate 28 that connects the main frame 22 and the lower frame 27.

Further, since the fuel pump 91 is disposed above the right and left lowermost portions 61b, which are the lowermost ends of the fuel tank 61, in a side view, the fuel pump 91 can be covered with the fuel tank 61 from both sides, and exposure of the fuel pump 91 to the outside can be suppressed, and the fuel pump 91 can be protected from the outside.

Fig. 4 is a plan view showing the tank 95 and its surroundings.

The fuel pump 91 is disposed on one side (left side) in the vehicle width direction with respect to a vehicle body center line 110 that extends forward and rearward through the center in the vehicle width direction of the vehicle body. In addition, a part of the fuel pump 91 (an end portion on the inner side in the vehicle width direction) overlaps the main frame 22 in a plan view, and protrudes to one side (left side) in the vehicle width direction from the cylinder portion 42.

An inlet pipe 107 and a return pipe 109 are connected to an upper surface of one end (left end) of the fuel pump 91 in the vehicle width direction. This makes it easy to extend the introduction pipe 107 and the return pipe 109 upward to connect them to the fuel tank 61.

The tank 95 is formed in a columnar shape, is disposed above the rear end portion of the main frame 22 and above the front end portions of the left and right seat frames 24, and the tank 95 overlaps the vehicle body center line 110 in a plan view. A center axis 95c of the tank 95 extends in the front-rear direction and overlaps the vehicle body center line 110 in plan view.

The filler pipe 96 connected to the front end surface 95a of the tank 95 is bent from above the main frame 22 toward the other vehicle width direction side (right side), extends upward, and is connected to the fuel fill inlet 88 (see fig. 2) of the fuel tank 61 (see fig. 2).

The cleaning pipe 97 connected to the front end surface 95a of the tank 95 extends forward along the main frame 22 above the main frame 22, is bent to the other side (right side) in the vehicle width direction above the cylinder portion 42, extends downward, and is connected to the throttle body 81 (see fig. 2).

The fresh air introduction pipe 98 connected to the rear end surface 95b (see fig. 2) of the tank 95 extends rearward on the vehicle body center line 110, and is bent obliquely rearward downward near the rear end portion.

As shown in fig. 1 to 3, the motorcycle 10 as a saddle-ride type vehicle includes a body frame 11, an engine 36, a fuel tank 61, and a fuel pump 91.

The vehicle body frame 11 includes a main frame 22 extending rearward and downward from the front seat pipe 21, and a seat frame 24 extending rearward from the main frame 22. The engine 36 includes a forward-tilting cylinder portion 42 disposed below the main frame 22. The fuel tank 61 is supported by the main frame 22 so as to straddle the main frame 22 in the vehicle width direction. The fuel pump 91 supplies the fuel stored in the fuel tank 61 to the intake device 51 of the engine 36. In the motorcycle 10, the fuel pump 91 is disposed below the main frame 22 and above the cylinder portion 42, and is disposed in the vehicle front direction of the uppermost portion 48a, which is the uppermost end of the cylinder portion 42. At least a part of the fuel pump 91 is covered by the fuel tank 61 from above and from the side.

According to this configuration, a relatively large space 93 can be secured below the main frame 22, above the forward-inclined cylinder portion 42, and in a position further toward the vehicle front than the uppermost portion 48a of the cylinder portion 42, and the fuel pump 91 can be brought close to the fuel tank 61 while being less likely to restrict other components. This enables the fuel pump 91 to be efficiently arranged. Further, since the fuel pump 91 is covered with the fuel tank 61, the fuel pump 91 can be protected by the fuel tank 61 and the appearance can be improved.

Further, as shown in fig. 4, the tank 95 is formed in a cylindrical shape having a central axis 95c extending in the vehicle front-rear direction, and the tank 95 is disposed along the main frame 22.

With this configuration, the bottom shape of the fuel tank 61 can be formed along the main frame 22 and the tank 95, and the shape of the fuel tank 61 can be made simpler than in the case where the center axis 95c of the tank 95 extends in the vehicle width direction.

Fig. 5 is a sectional view taken along line V-V in fig. 2.

The bottom plate 87 of the fuel tank 61 includes: an upper wall 87a formed in a flat shape; and a pair of left and right side walls 87b integrally extending downward from both ends of the upper wall 87 a. Thus, the floor panel 87 is formed with a recess by the upper wall 87a and the left and right side walls 87b, and the tank 95 is protected by the upper wall 87a and the left and right side walls 87b from above and outside in the vehicle width direction.

A tank support frame 113 is provided on the lower surface 87c of the upper wall 87a, and the tank 95 is supported by the tank support frame 113.

The tank support frame 113 includes: a plate-shaped upper holder 114 attached to a lower surface 87c of the upper wall 87a of the bottom plate 87; and a tank holder 115 that surrounds the tank 95, holds the tank 95, and engages with both end portions of the upper holder 114.

The tank holder 115 includes a pair of claw portions 115a at both ends, and the pair of claw portions 115a are detachably engaged with a pair of openings 114a provided at both ends of the upper holder 114.

An inward projecting portion 87d projecting inward in the vehicle width direction is formed on the side wall 87b on one side (left side) in the vehicle width direction, and an inlet port 117 connected to the inlet pipe 107 and a return port 118 connected to the return pipe 109 are provided at a lower end portion 87e of the inward projecting portion 87 d.

Since the left and right seat frames 24 are disposed below the tank 95, the tank 95 can be protected by the left and right seat frames 24.

The above-described embodiment is merely one embodiment of the present invention, and can be modified and applied arbitrarily without departing from the scope of the present invention.

For example, in the above embodiment, the pump mounting bracket 102 is provided on the reinforcing plate 28 as shown in fig. 3, but the present invention is not limited thereto, and the pump mounting bracket 102 may be provided on the main frame 22 and the fuel pump 91 may be mounted on the pump mounting bracket 102.
