A fuel tank unit may include a fuel tank, a canister configured to adsorb and desorb vapor generated in the fuel tank, a vapor conduit communicating the fuel tank with the canister, and a full tank fuel level limiting valve device connected to a fuel tank-side end of the vapor conduit. The full tank fuel level limiting valve device includes a full tank fuel level limiting valve and an actuator. The full tank fuel level limiting valve includes a float that is configured to float due to a buoyancy force of fuel in the fuel tank so as to close the full tank fuel level limiting valve when the fuel tank is filled up. The actuator includes a valve closure prevention member that is configured to move and press the float when the actuator is activated, so as to prevent the float from moving in a valve closing direction.
