A fuel tank ventilation valve includes a float valve, a float control mechanism, and a barrier member. The float valve includes a float and a float chamber. The float chamber is provided by a case. The float control mechanism controls the area of a fuel opening so that a fuel outflow speed from the float chamber is slower than a fuel inflow speed into the float chamber. The barrier member is located between an opening for a ventilation passage and the float. The barrier member suppresses fuel intrusion. The fuel tank ventilation valve is capable of preventing an outflow of a liquid component.
