Abstract: A fuel tank cap structure and method of manufacturing which prevents a parting line formed on a cover member in the process of injection molding from being undesirably shaven. The fuel tank cap includes a casing body and a cover member that is rotatable in one direction relative to the casing body via a ratchet mechanism when a torque of or above a predetermined level is applied to the cover member. The cover member has fitting projections that are held by an outer ring member of the casing body. A slide mold is used for manufacturing the cover member having the fitting projections that are undercut in the injection molding. This causes a parting line to be formed on a top wall of the cover member. Anti-shaving projections formed at substantially the same height as that of the parting line prevent the parting line from being slid against the outer ring member and shaven.

Abstract: A fuel tank cap which enables static electricity to be discharged quickly and stably when the user manually touches a fuel tank cap to open or close the cap.

The four discharge projections are arranged in a third radial direction that has an angle of 45 degrees with respect to both a first radial direction and a second radial direction. The first radial direction, in which a handle member of the cover member is arranged, gives the maximum contraction of the cover member, whereas the second radial direction gives the minimum contraction of the cover member. The four discharge projections are arranged on a circle about the center of the cover member to reduce the effect of resin contraction.
