Claims

[Scope of Claim for Utility Model Registration] (1) A plate material is attached around the fuel supply port of an automobile fuel tank, the plate material is wrapped around the fuel supply port, and has two end plate portions that face each other and are separated from each other. Pivot pins are rotatably attached to the two end plates, one end of which protrudes from the center of the pivot pin, and the other end of the link has an annular shape at each end. A remotely controllable pneumatic cylinder connected to the central part of the grooved bar is attached to the car body, and a piston rod protrudes from one end of the pneumatic cylinder.
having a forked end consisting of two branch rods, each branch rod having a roller on the inside;
each roller is fitted into a corresponding annular groove at each end of said bar and is movable along said annular groove, and a fuel cap is integrally constructed with said link;
The fuel cap has a rubber block projecting from its inside, and the piston rod is connected to the first
The remote control fuel cap device for a motor vehicle is constructed such that the rubber block of the fuel cap is raised to expose the fuel supply port when the piston rod is in the second position, and the rubber block of the fuel cap seals the fuel supply port when the piston rod is in the second position. (2) the rubber block has a rubber flange in its center so as to seal the fuel supply port when the fuel cap shields the fuel supply port; 2. The remote control according to claim 1, wherein the fuel cap is configured to fit closely against the outer end of the port and to form a smooth surface with the outer surface of the vehicle when the fuel cap shields the fuel supply port. Fuel cap device. (3) An annular gasket is formed on the inner wall of the fuel supply port so as to seal the fuel supply port together with the rubber block when the piston rod is in the second position. 2. The remotely controlled fuel cap device according to item 1. 4. The remotely operated fuel cap device according to claim 1, wherein a passage is formed within the rubber block of the fuel cap to equalize the pressure inside and outside the fuel tank. (5) The remotely controlled fuel cap according to claim 1, characterized in that an adjustment screw is installed at another location on the pneumatic cylinder to enable manual operation in case the pneumatic cylinder does not function properly. Device.
