Abstract
Abstract The diameter of a filler cap closing a filler tube is smaller than that of an opening of a filler cover secured to a rear side panel of a vehicle body, through which the filler tube extends outwardly. The filler cover is fastened to a filler neck flange fitted on the filler tube by means of headed screws which pass through spreadable slots formed in the filler cover and are fixed to the filler neck flange.
