ABSTRACT:
The prevent invention relates to a shutter of a leaf spring type supported at a filler neck portion of a fuel filler pipe by a shutter support portion within the filler pipe. The invention aims to improve a durability in opening and closing action of the shutter. The shutter according to the invention is formed to have an arm portion extending from a shutter working portion, the arm portion being elastically deformed when the shutter opens, and a turned end portion extending from the arm portion toward the shutter working portion. The turned end portion is held by the shutter support portion at a location near the shutter working portion such that deformation of the turned end portion is not restricted when it elastically deforms in accordance with the opening movement of the shutter. Alternatively, the shutter main body, the shutter working portion and the arm portion which elastically deforms when the shutter working portion opens are integrally formed from a piece of spring plate, so that the number of component parts is reduced and attachment work of the shutter to the filler pipe is facilitated.
