The storage case 43 is stored in the vehicle body cover 13 below the driver seat 24. An opening is defined in an upper end of storage case 43. The opening of the storage case 43 is opened and closed by the driver seat 24.

As shown in fig. 3 and 4, the shelf 25 includes left and right vertical frames 25a extending in the vehicle front-rear direction along the left and right rear frames 16 and connected at rear ends to the handle members 27, and a plurality of lateral frames 25b connecting the left and right vertical frames 25a to each other and supporting the passenger seat 26 from below. As shown in fig. 2, each of the vertical frames 25a is coupled to the corresponding second horizontal region 16c of the rear frame 16 by the front and rear base bodies 44. The base body 44 is welded to the rear frame 16, for example. The base 44 arranges the shelf 25 above the second horizontal region 16c of the rear frame 16. The vertical frame 25a and the horizontal frame 25b are formed of a pipe material made of a metal material such as steel, aluminum, or stainless steel, for example.

Hooks 45 for a rack rope projecting downward are fixed to the respective frames 25a at two front and rear positions. The hook 45 is formed of a linear shaft body 45a that is displaced outward as it moves downward. A ball 45b for preventing the shaft from coming off is coupled to a lower end of the shaft 45 a. The shelf cord may be wrapped around the hook 45. The shelf cord functions when securing the goods on the shelf 25.

As shown in fig. 2, the fuel tank 46 is fixed to the rear frame 16 below the shelf 25. The fuel tank 46 stores fuel such as gasoline. As shown in fig. 3 and 4, the fuel tank 46 is provided with a fuel fill inlet 47 below the driver seat 24. The fuel fill port 47 is closed with a cap. A fuel pump 48 is attached to the fuel tank 46 behind the fuel fill inlet 47. The fuel pump 48 is electronically controlled. A control harness 49 is connected to the fuel pump 48. At the time of connection, a coupler is incorporated at the front end of the harness 49, for example.

As shown in fig. 3, the handle lever 27a extends in the left-right direction parallel to the axle of the rear wheel WR. The handle member 27 is formed of a pipe material made of a metal material such as steel, aluminum, or stainless steel, for example, as in the case of the vertical frame 25a and the horizontal frame 25b of the shelf 25. As shown in fig. 5, a cylindrical rotation shaft 51 extending in the left-right direction in parallel with the axle of the rear wheel WR is attached to the left and right ends of the handle member 27. The axial center 51a of the left and right rotary shafts 51 coincides with the swing axis of the handle member 27. As shown in fig. 6, bearings 52 for rotatably supporting the rotary shaft 51 of the handle member 27 around the shaft center 51a are fixed to the rear ends of the left and right vertical frames 25 a. The axial center 51a coincides with the axis Hx.

As shown in fig. 5, the regulating pieces 53 are supported at the left and right ends of the handle member 27 at positions offset from the rotary shaft 51. As shown in fig. 6, the regulating piece 53 has a screw shaft 53a, and the screw shaft 53a has an axial center parallel to the axial center 51a of the rotating shaft 51. The first positioning hole 54a is formed through the handle member 27. The threaded shaft 53a enters the first positioning hole 54a and penetrates the handle member 27. An external thread is engraved on the outer periphery of the threaded shaft 53 a. A hand 53b seated on the outward surface of the handle member 27 is formed at the outer end of the threaded shaft 53 a. The user of the handle member 27 can grip the grip 53b and rotate the restricting piece 53 about the axial center.

A nut member 55 that engages with the screw shaft 53a of the regulating piece 53 is fixed to the vertical frame 25a of the shelf 25 at a position offset from the rotating shaft 51. The nut member 55 is provided with a female screw that meshes with the male screw of the threaded shaft 53 a. When the regulating piece 53 is screwed into the nut member 55, the regulating piece 53 can fix the regulating piece 53 to the shelf 25 by friction between the grip 53b of the regulating piece 53 and the outward surface of the handle member 27. When the restricting piece 53 enters the first positioning hole 54a, the handle member 27 is fixed at the first position PSf rising upward from the load plane HP as shown in fig. 5. The distance between the center position of the nut member 55 and the axial center 51a of the rotating shaft 51 is equal to the distance between the center position of the first positioning hole 54a and the axial center 51a of the rotating shaft 51.

As shown in fig. 5, the handle member 27 is provided with a second positioning hole 54b formed at a position offset from the first positioning hole 54a about the axial center 51a of the rotary shaft 51. The distance between the center position of the second positioning hole 54b and the shaft center 51a of the rotating shaft 51 is equal to the distance between the center position of the first positioning hole 54a and the shaft center 51a of the rotating shaft 51. When the restricting piece 53 enters the second positioning hole 54b and is screwed into the nut member 55, the handle member 27 is tilted outward and backward, and is fixed at the second position PSs at substantially the same height as the cargo plane HP.

When the passenger seat 26 is mounted on the shelf 25, a rear-row rider can sit on the passenger seat 26. At this time, if the grip member 27 is fixed at the first position PSf, the rear rider can grip the grip lever 27a of the grip member 27 during running. The first positioning hole 54a is positioned to be aligned with the nut member 55 when the handle member 27 is fixed. The restricting piece 53 is screwed into the nut member 55 through the first positioning hole 54 a.

As shown in fig. 7, the passenger seat 26 can be detached from the shelf 25. At this time, the handle member 27 can be switched to the second position PSs. At the time of switching, the regulating piece 53 is detached from the nut member 55. The handle member 27 moves around the axial center 51a of the rotating shaft 51. The position of the second positioning hole 54b is aligned with the nut member 55. The restricting piece 53 is screwed into the nut member 55 through the second positioning hole 54 b. By using the handle member 27 which is not necessary when the passenger seat 26 is removed, the substantially large shelf 25 can be secured. The cargo LG can be mounted on the enlarged rear shelf 25. The load capacity of the motorcycle 11 is improved while suppressing an increase in the weight of the luggage carrier 25. The convenience of use of the shelf 25 is improved.

Since the passenger seat 26 is interrupted forward of the rear end of the vertical frame 25a of the shelf 25, the handle member 27 may be in the first position PSf or the second position PSs when the passenger seat 26 is attached or detached. When the first position PSf and the second position PSs are switched, the passenger seat 26 may be attached to the shelf 25 or detached from the shelf 25.

In the present embodiment, the handle member 27 is formed in a shape surrounding a space behind the rear end edge of the shelf 25. Therefore, the shelf 25 can be widely used at the rear. The handle bar 27a can be disposed behind the rear rider if the handle member 27 stands from the cargo plane HP. The handle member 27 is connected to the rear end of the shelf 25 so as to be swingable about an axis (coinciding with the axial center 51a of the rotary shaft 51) extending in the vehicle lateral direction. When the passenger seat 26 is mounted in the space on the shelf 25, the handle member 27 does not protrude to the left and right of the passenger seat 26, and interference between the feet of the rear rider and the handle member 27 can be avoided when getting on or off the vehicle. The back row rider can easily get on or off the vehicle. Since the handle member 27 is coupled to the rear end of the shelf 25, the handle member 27 does not have to be excessively large.

The handle member 27 maintains an inclined posture in which it is displaced rearward as it moves upward at the first position PSf. Even if the passenger seat 26 is extended to the rear end of the shelf 25, a space for the rear rider's hand to be inserted between the handle bar 27a and the passenger seat 26 is secured. The handle bar 27a can be well gripped.

The carrier 25 of the present embodiment includes a vertical frame 25a extending in the vehicle longitudinal direction along the left and right rear frames 16 and connected to the handle member 27 at the rear end, and a horizontal frame 25b connecting the left and right vertical frames 25a to each other and supporting the passenger seat 26 from below. By forming the shelves 25 on the frame structure, the space under the shelves 25 can be easily reached from the gap space of the frame. When the passenger seat 26 is removed during maintenance of the motorcycle 11, for example, an operator can easily reach the fuel pump 48.

In the shelf 25 of the present embodiment, the vertical frame 25a, the horizontal frame 25b, and the handle member 27 are formed of a tube material. The rack 25 constituted by the vertical frame 25a and the horizontal frame 25b is integrated with the handle member 27. Good design can be ensured.

The motorcycle 11 has a restricting piece 53 that fixes the handlebar member 27 in the first position PSf and the second position PSs, respectively. The handle member 27 can be fixed in the first position PSf or the second position PSs due to the function of the restricting piece 53. The movement of the handle member 27 can be restricted. The handle lever 27a can be well grasped by the rear-row rider. The handle member 27 can function well as the shelf 25.
