Abstract
In a breather system for a fuel tank having a tank body, a fuel supply port opened and closed by a fuel cap provided in a central portion of an upper wall of the tank body, wherein an upper end of a breather pipe is located to face a central portion of a fuel supply port. When the fuel supply port is closed by the fuel cap, a breather chamber is formed in the fuel cap and the breather chamber communicates with the breather pipe. Thus, when the fuel tank is inclined, fuel is prevented from entering the breather pipe, and the fuel supply port is not immersed in the fuel, thereby maintaining the sealability of the fuel supply port.
