The uncovered refueling assembly (1) is mounted at the top end of a refueling pipe (2) extending from a fuel tank. The uncovered refueling assembly (1) is provided with a main body (10), a flapper valve (11), and a pair of stop ribs (16). An oil filling port (10a) into which a nozzle (30) of the oil gun (3) is inserted is formed in the main body (10). The flapper valve (11) is provided inside the main body (10) so as to be openable and closable, and opens and closes the filler port (10a). The stopper rib (16) protrudes inward from the inner surface of a liquid fuel flow path formed inside the main body (10). The pair of stopper ribs (16) protrude inward so as to face each other, and restrict the insertion depth of the nozzle (30). The shortest distance between the pair of stopper ribs (16) is set to be smaller than the outer diameter of the tip of the nozzle (30).

    无盖加油组件(1)安装于从燃料箱延伸设置的加油管(2)的顶端。无盖加油组件(1)具备主体(10)、挡板阀(11)、以及一对止动肋(16)。在主体(10)形成有供加油枪(3)的喷嘴(30)插入的加油口(10a)。挡板阀(11)可开闭地设置在主体(10)的内部,使加油口(10a)开闭。止动肋(16)从在主体(10)的内部形成的液体燃料的流路内表面朝向内方突出。一对止动肋(16)以彼此朝向对方的方式向内方突出,限制喷嘴(30)的插入深度。一对止动肋(16)之间的最短距离设定得比喷嘴(30)的顶端外径小。
