    摘要: The object of this invention is to improve the safety of an engine by preventing fuel which might splash out of the fuel inlet on top of the fuel tank or drip onto the tank during fueling from coming in contact with the hot cylinder or any electrical components. Another object of this invention is to prevent vibration of the fuel tank and the noise which such vibration would cause. The fuel tank according to this invention has an upper and a lower portions joined by a flange, both of which are made from a resin material. The upper portion has a trapezoidal depression in its center which surrounds the fuel inlet and slopes downward toward one side of the tank. The overall surface of the upper portion is convex and also slopes downward toward the same side of the tank. A number of grooves on either side of the central depression run in the same direction and open onto the same side of the tank. The two halves of the tank are welded at the web of a ribbed flange which extends around the entire periphery.
