Abstract
A fuel tank structure comprising a fuel tank; a canister that adsorbs evaporated fuel within the fuel tank, and that releases vapor after adsorption of evaporated fuel; a full tank regulating valve within the fuel tank that becomes a closed state due to a float floating in fuel when a fuel liquid surface reaches a full tank liquid level that is set in advance; a communication pipe that communicates the fuel tank and the canister via the full tank regulating valve, a cross-sectional area varying valve that, when tank internal pressure that is applied from inside of the fuel tank increases, reduces a cross-sectional area of a flow path of vapor that flows toward the float; and a suppressing member that is positioned between the cross-sectional area varying valve and the float, and that suppresses airflow from the cross-sectional area varying valve from directly abutting the float.
