PROBLEM TO BE SOLVED: To provide an inexpensive fuel filler tube capable of keeping sealability of a connection part between two cylindrical bodies high.SOLUTION: A first cylindrical body 2 has a fuel filler 2a provided at one end. A second cylindrical body 3 has one end connected to the other end of the first cylindrical body 2, and has the other end connected to a fuel tank 10. The first cylindrical body 2 is designed to be lower in thermal expansion coefficient than the second cylindrical body 3 and lower in swelling property than it. The first and second cylindrical bodies 2 and 3 are integrated together by pressing the side of one end of the second cylindrical body 3 into the side of the other end of the first cylindrical body 2 so that the side of the other end of the first cylindrical body 2 and the side of one end of the second cylindrical body 3 can overlap each other.SELECTED DRAWING: Figure 3
【課題】2つの筒体における接続部分のシール性を高く維持できる低コストな燃料給油管を提供する。【解決手段】第1筒体2は、一端に給油口2aを有する。第2筒体3は、一端が第1筒体2の他端に接続され、他端が燃料タンク10に接続される。第1筒体2は、第2筒体3よりも熱膨張係数が低く、且つ、膨潤性が低くなるように設計される。第1筒体2及び第2筒体3は、第1筒体2の他端側と第2筒体3の一端側とが重なり合うように第1筒体2の他端側に第2筒体3の一端側を圧入することで一体になっている。【選択図】図3
