Abstract: A fuel tank structure of an all-terrain vehicle is provided. The all-terrain vehicle includes a vehicle frame unit, a fuel tank arranged on the vehicle frame unit, a seat cushion arranged on the vehicle frame unit, a pair of rear wheels rotatably mounted to a rear section of the vehicle frame unit, and a power unit arranged on the vehicle frame unit. The power unit is connected to an exhaust unit. The vehicle frame unit includes a rear carrier rack and a rear ancillary tube assembly. The fuel tank is arranged rearwardly of the power unit and located below the rear carrier rack. The fuel tank includes a body portion, which is formed with a lower buffering fuel accommodation extension section extending in a direction toward a lower side of the vehicle body, so as to increase the weight of the fuel tank.

Abstract: A tank holding device is adapted to be mounted to a vehicle. The vehicle includes a mounting frame, a holding frame that is disposed on the mounting frame, and a tank that is disposed between the mounting frame and the holding frame. The tank holding device includes a positioning unit that is adapted to be connected to the holding frame and adapted for pushing the tank tightly against the mounting frame so as to secure the tank on the mounting frame.

Abstract: A fuel storage device is adapted to be mounted to a vehicle, and has a tank, a pump, a fuel tube, a plurality of connecting tubes, and a vent hole. The tank has a top wall formed with a plurality of vent holes . At least one of the vent holes is arranged at a side of a first imaginary line which extends through a reference point of the top wall and which is perpendicular to a longitudinal direction of the vehicle, and at least one of the remaining of the vent holes is arranged at an opposite side of the first imaginary line. The fuel tube is for passage of fuel from the pump. The connecting tubes are connected respectively to the vent holes, and the vent tube is adapted for communicating the connecting tubes with the external environment.

Abstract: A tank holding frame for a vehicle body includes front and rear beams connected to the vehicle body, a first beam connected to the vehicle body and the front beam, a second beam connected removably to the vehicle body, and a guard member having at least one end connected removably to a respective one of the first and second beams. A fuel tank is removable from a tank holding space cooperatively defined by the front, rear, first, second beams, the guard member, and the vehicle body when the second beam and the guard member are detached from the tank holding frame.

Abstract: A hood positioning structure is provided for a multi-purpose vehicle, including a crossbar and two brackets. The crossbar has opposite ends forming connection portions and a middle section forming a fixing seat, by which connection portions and fixing seat, the crossbar is fixed to a hood of the vehicle. Each bracket includes a U-shaped channel member and is coupled to an end of the crossbar respectively. A free end of the bracket forms a notch that spaces side walls of the bracket to form a coupling portion and forms a stop. The coupling portion is pivotally connected to the chassis to allow the hood to be lifted up for opening and the hood is positioned by the stop of the bracket abutting a predetermined portion of the chassis to thereby set the hood in a stable open position for easy maintenance and repairing of the vehicle.
