Abstract: A valve device for a fuel tank includes: a housing including a peripheral wall portion, a partition wall, a valve chamber, a ventilation chamber, and an opening; and a float valve that is accommodated in the valve chamber so as to be able to rise and descend to open and close the opening. The housing includes a float valve support portion that supports the float valve. A full tank regulation opening that opens in an axial direction and that is configured to allow the inside of the fuel tank and an inside of the valve chamber to communicate with each other, is formed in the peripheral wall portion above the float valve support portion. The full tank regulation opening enables continuous refueling from the refueling nozzle when the full tank regulation opening is not immersed, and stops the continuous refueling when the full tank regulation opening is immersed.

Abstract: There is provided a valve device for a fuel tank. A housing is provided with a valve chamber and a vent chamber defined via a partition wall. The partition wall is provided with an opening. A float valve is received in the valve chamber to be movable up and down. The float valve includes a lower member and an upper member. The upper member includes a top portion, an outside wall extending from the top portion, and an elastic engaging piece configured to engage with an engaged portion of the lower member. The elastic engaging piece extends from a location on the back surface of the top portion, which is located inward from the outside wall, and is configured to elastically return after being bent in an outward radial direction of the upper member and thus to engage with the engaged portion of the lower member.
