Thus, when the off-road vehicle 2 is observed from a lateral point of view, the fuel tank 24 and the exhaust unit 28 partially overlap each other. More specifically, the filling opening 241 and the fuel outlet pump 242 of the fuel tank 24 are located outside the upper lateral tube 211 and the lower lateral tube 212 on the right side of the frame unit 21 of the vehicle (the right-hand side of the user is considered to be the right side) and located on the front right side of the rear luggage rack 215 of the vehicle frame unit 21, to ensure that the the entry and exit of the fuel contained in the fuel tank 24 are not affected by the high temperature generated by the exhaust unit 28, with the aim of improving the safety of use of the fuel tank 24. Furthermore, since the filler opening 241 and the fuel outlet pump 242 of the fuel tank 24 are located outside the upper side tube 211 and the lower side tube 212 on the outside. right side of the vehicle frame unit 21 (the right-hand side of the user is considered to be the right side), and are located on the front right side of the rear luggage rack 215 of the imitated frame 21 of the vehicle, so that the maintenance of the filling opening 241 and the fuel outlet 242 of the fuel tank 24 can be carried out conveniently.
    The effective result of the present invention is that the fuel tank 24 is disposed between the upper side tubes 211 and the lower side tubes 212 of the vehicle frame unit 21 towards the rear end of the body of the vehicle. so as to place the fuel tank 24 behind the drive unit 27 to locate it under the seat cushion 25, the fuel tank 24 being away from the yoke 271 of the power unit 27, and the filling opening 241 and the fuel pump outlet 242 of the fuel tank 24 being remote from the side on which the exhaust unit 28 is located; more specifically, the filling opening 241 and the fuel outlet pump 242 of the fuel tank 24 are located outside the upper side tube 211 and the lower side tube 212 on the right side of the vehicle frame format unit. 21 (the right-hand side of the user being considered as the right side), and located on the front right side of the rear luggage rack 215 of the vehicle frame unit 21, to ensure that the The entry and exit of the fuel contained in the fuel tank 24 are not affected by the high temperature generated by the exhaust unit 28, in order to improve the safety of use of the fuel tank 24.
    Another effective result of the present invention resides in the fact that the maintenance of the filling opening 241 and the fuel outlet pump 242 of the fuel tank 24 can be carried out conveniently, having the fuel tank 24 arranged between the upper side tubes 211 and the lower side tubes 212 of the vehicle frame unit 21 towards the rear end of the vehicle body so as to place the fuel tank 24 behind the drive unit 27 and locate it under the seat cushion 25, and making the filling opening 241 and the fuel outlet pump 242 of the fuel tank 24 away from the side on which the exhaust unit 28 is located; more specifically, the filling opening 241 and the fuel outlet pump 242 of the fuel tank 24 are located outside the upper side tube 211 and the lower side tube 212 on the right side of the frame unit 21. vehicle (the right-hand side of the user being considered the right side) at the front right side of the rear luggage rack 215 of the vehicle frame unit 21.
    Another effective result of the present invention is that by providing a shroud 3 fitted over an outer circumference of the lower portion 24b and the bottom portion 24c of the fuel tank 24. The shroud 3 can help prevent foreign bodies, such as small pebbles that bounce off the ground, from striking the lower part 24b and the bottom portion 24c of the fuel tank 24, and can also isolate the fuel tank 24 screw-to of the exhaust unit 28 so that the protective casing 3 can provide a protective effect to the lower part 24b and to the bottom part 24c of the fuel tank 24.
    Another effective result of the present invention resides in the fact that by arranging on the protective envelope 3 a flow opening 31 turned towards the ground, this flow opening 31 can allow the fuel to spread out of the reservoir. fuel 24 and to be collected by the protective envelope 3 so that it flows through the flow opening 31 to the ground, thus improving the safety of use of the fuel tank 24.
    Another effective result of the present invention is that by providing the upper end portion 24a of the fuel tank 24 with a clearance recess 243, on the one hand, the rigidity and strength of the part of the upper end 24a of the fuel tank 24 can be improved, and, on the other hand, interference with other components disposed above the fuel tank 24 can be avoided, thereby improving the use of the fuel tank. fuel 24.
