Abstract:
To provide a fuel tank vent valve which can prevent outflow of a liquid component.SOLUTION: A vent valve 2 for a fuel tank includes: a float valve 21; a float control mechanism 61; and a barrier member 71. The float valve 21 includes a float 31 and a float chamber 32. The float chamber 32 is provided by a case 22. The float control mechanism 61 controls an area of a fuel opening so that a fuel outflow speed from the float chamber 32 becomes slower than a fuel inflow speed into the float chamber 32. The barrier member 71 is located between an opening 26 for a ventilation passage and the float 31. The barrier member 71 inhibits entry of a fuel.SELECTED DRAWING: Figure 1
