By suitably selecting the size of the communication hole and/or the number thereof, a desired delay in the dropping of the liquid fuel level in the housing following the filling up of the fuel tank can be achieved. Thereby, overfilling of the fuel tank can be avoided. As the float assembly drops to such an extent as to clear the communication hole, the fuel vapor is allowed to flow more freely into the interior of the housing via the communication hole, and this causes an increase in the speed of the float to drop. Thereby, the venting of the fuel tank can be resumed at an appropriately earlier stage following the filled up state of the fuel tank.
