  6. The rear structure of the straddle-type vehicle (1) according to claim 1, wherein an upper half portion of the lighting device (31), which is long in a vehicle width direction, is a brake lamp (32), lower half portions of the lighting device (31), which are separated in the vehicle width direction, are a pair of left and right turn signal lamps (33), the brake lamp (32) is positioned above the concave housing (41), and the turn signal lamps (33) are positioned on sides of the concave housing (41).

Description

TECHNICAL FIELD The present disclosure relates to a rear structure of a straddle-type vehicle. BACKGROUND ART In a scooter-type straddle-type vehicle or the like, a fuel tank is often laid out inside a seat frame cover at a rear portion of the vehicle. As a straddle-type vehicle of this type, a vehicle in which a fuel supply port of a fuel tank is positioned behind a seat is known (for example, see JPH02-155884A). In the straddle-type vehicle described in JPH02-155884A, a housing space for the fuel tank is ensured behind the seat, and the fuel supply port can be accessed by opening an opening and closing cover covering an upper surface of the housing space. In order to access the housing space from the rear, a configuration is also proposed in which the rear of the housing space is covered with the opening and closing cover, and a lighting device is disposed below the opening and closing cover. In order to ensure visibility of the lighting device, it is desirable to dispose the lighting device at a high position. In a case where the lighting device is disposed below the opening and closing cover as described above, the visibility of the lighting device deteriorates. In addition, since the lighting device is positioned below the fuel supply port, there is a possibility that the fuel spilled from the fuel supply port adheres to the lighting device and a lens deteriorates. In order to prevent the deterioration of the lens, it is necessary to select a material having high resistance to the fuel or to add a protective member, and there is a problem that the cost increases. In US 8,668,037 B2, an electrically operated vehicle is disclosed including a motor that drives the rear wheels, a battery that is arranged above the motor, and a lower battery that is placed between the right and left rear wheels. The lower battery and motor are arranged in a distributed manner over an axle of the rear wheels between a vehicle front side of the axle of the rear wheels and a vehicle rear side of the axle of the rear wheels. An upper end portion of a rear cushion is supported on a vehicle body frame, and the battery and the motor are supported on a lower end of the rear cushion. SUMMARY OF INVENTION An object of the present disclosure is to provide a rear structure of a straddle-type vehicle capable of improving user convenience with a simple structure. The scope of the present invention is defined by the appended claims. According to the rear structure of a straddle-type vehicle of one aspect of the present disclosure, even in a case where the fuel tank or a battery is disposed below the seat, the lighting device is positioned above or on a side of the concave housing, and the visibility of the lighting device does not deteriorate. In addition, in a case where the fuel tank is disposed below the seat, the lighting device is not positioned below the filler port of the fuel tank. Therefore, the fuel is less likely to adhere to the lighting device, and it is not necessary to select a material having high resistance to the fuel as the material of the lighting device or to add a member for protecting the lighting device from the fuel. Accordingly, it is possible to improve user convenience with a simple structure. BRIEF DESCRIPTION OF DRAWINGS FIG. 1 is a left side view of a straddle-type vehicle according to a first embodiment.FIG. 2 is a schematic rear view of a rear structure of the straddle-type vehicle according to the first embodiment.FIG. 3 is a schematic cross-sectional view of the rear structure of FIG. 2 taken along a line A-A.FIG. 4 is a schematic cross-sectional view of a rear structure of a straddle-type vehicle according to a second embodiment.FIG. 5 is a schematic rear view of a rear structure of a straddle-type vehicle according to a modification. DESCRIPTION OF EMBODIMENTS A fuel tank or a battery is disposed at a rear portion of a straddle-type vehicle according to an aspect of the present disclosure. A vehicle rear side is illuminated by a lighting device on a rear side of the fuel tank or the battery. A filler port of the fuel tank or a charging port of the battery is surrounded by a concave housing. Since the lighting device is positioned above or on a side of the concave housing, the visibility of the lighting device does not deteriorate even in a case where the fuel tank or the battery is disposed below a seat. In addition, in a case where the fuel tank is disposed below the seat, the lighting device is not positioned below the filler port of the fuel tank. Therefore, the fuel is less likely to adhere to the lighting device, and it is not necessary to select a material having high resistance to the fuel as the material of the lighting device or to add a member for protecting the lighting device from the fuel. Accordingly, it is possible to improve user convenience with a simple structure. [Embodiment] <First Embodiment> Hereinafter, a straddle-type vehicle according to a first embodiment will be described wit
