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, there is known a vehicle in which an upper wall of a housing space of a fuel tank is formed by an opening and closing cover (for example, see JPH02-155884A). In the straddle-type vehicle described in JPH02-155884A, the housing space of the fuel tank is ensured behind a seat, and the fuel tank is disposed in the housing space with a fuel supply port facing upward. The design of the rear portion of the straddle-type vehicle is improved by covering the fuel supply port of the fuel tank with the opening and closing cover as an exterior component. In a rear structure of the straddle-type vehicle described in JPH02-155884A, in a case where lock of the opening and closing cover is released, the opening and closing cover is slightly opened, and a fingertip is inserted into a gap of the opening and closing cover to open the opening and closing cover. In order to automatically open the opening and closing cover, a complicated structure using a torsion spring, a damper or the like having a large stroke is required. WO 2022/091110 A1 discloses a charging inlet assembly for a vehicle. The charging inlet assembly comprises one or more structural members which are removably mounted on each other such that if one of the structural members gets damaged, the charging inlet need not be removed from the vehicle and the damaged structural member can be removed and replaced by a new part. 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, the opening and closing cover is automatically opened by its own weight in a case where the opening and closing cover is unlocked. A complicated structure using a torsion spring, a damper, or the like having a large stroke for opening the opening and closing cover by its own weight becomes unnecessary. 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 filler port of the fuel tank or a charging port of the battery is surrounded by a concave housing. The filler port of the fuel tank or the charging port of the battery is configured to be opened and closed by an opening and closing cover. The opening and closing cover is locked in a case where the opening and closing cover is closed. The opening and closing cover is configured to be opened by its own weight in a case where the opening and closing cover is unlocked. A complicated structure using a torsion spring, a damper, or the like having a large stroke for opening the opening and closing cover by its own weight becomes unnecessary. 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 with reference to the accompanying drawings. FIG. 1 is a left side view of the straddle-type vehicle according to the first embodiment. In the following drawings, an arrow FR indicates a vehicle front side, an arrow RE indicates a vehicle rear side, an arrow L indicates a vehicle left side, and an arrow R indicates a vehicle right side. As shown in FIG. 1, a straddle-type vehicle 1 of a scooter type is formed by mounting various covers, as a vehicle body exterior, on an underbone type vehicle body frame that is not shown. A front frame cover 11 is provided in the vehicle front side. A front leg shield 12 for protecting the foot of a rider is provided in a rear side of the front frame cover 11. A foot board 13 extends rearward from a lower end of the front leg shield 12. A seat frame cover 14 is provided behind the foot board 13. A foot rest space for the rider is formed in front of a seat 20 by the front leg shield 12 and the foot board 13. A handle 15 is provided in an upper side of the front frame cove
