A resin filler tube (30) includes: a tubular body(32a); a flange (32b) that protrudes radially outward from an end of the tubular body (32a)on a fuel tank side, over an entire circumference, has a plurality of layers (61-65) that are of same kinds as those of the tubular body, has outer faces all of which are formed of an outermost layer material, and has a first end face(32b1), in an axial direction, forming a weld surface to be welded to an outer circumferential edge of an opening hole(21) of the fuel tank(20); and a leading end tubular portion (32c) extending from a radially inner portion of the flange toward a leading end of the filler tube, and having an annular recessed groove formed at a portion of an outer circumferential surface on the flange side, over an entire circumference, for storing a melt burr generated in welding of the first end face(32b1).

    树脂制加油管(30)具备:筒状主体(32a);凸缘(32b),其从筒状主体(32a)中的燃料箱(20)侧的端部朝向径向外侧且遍及整周地伸出,具有与筒状主体(32a)相同种类的多个层(61‑65),外表面全部由最外层材料成形,轴向上的第一端面(32b1)构成与燃料箱(20)的开口孔(21)的外侧周缘熔接的熔接面;以及前端筒部(32c),其从凸缘(32b)的径向内侧的部位向加油管(30)的前端侧延伸,在外周面中的凸缘(32b)侧的部位具有遍及整周地形成并且对伴随第一端面(32b1)的熔接而产生的熔融毛刺进行容纳的环状凹槽(32c2)。
