Abstract
This invention relates to a check valve of a fuel tank which is provided in an end portion of a fuel supply pipe for introducing fuel to the fuel tank, which end portion is located inside of the tank. The check valve comprises a valve plate which is large enough to cover the end face of the pipe, and a valve support which supports the valve plate by a connecting pin serving as a hinge, the valve support being of a semicylindrical shape having an inner diameter which is substantially equal to an outer diameter of the pipe to which the valve support is attached, the valve support being attached to the pipe by engaging concave and convex fitting means which are formed at least on end portions of the valve support on both sides and on the associated pipe.
