ABSTRACT:
An opening and closing device of a gasoline tank cap is disposed between an upper cap and a base of the tank cap, and includes a valve, a valve cap controlling the valve to rotate to let its valve hole communicate or not with an upper opening of the upper cap. Thus, the tank cap is not needed to be taken off completely for pouring gasoline in the tank. So filling gasoline in the tank is quite convenient, saving time, and preventing the tank cap from being lost by frequent removing for pouring gasoline in.
