<p>PROBLEM TO BE SOLVED: To assemble a vent valve assembly along one directional axis and make a narrow floor space required for assembling work.SOLUTION: A vent valve assembly comprises a first housing part, a second housing part, a third housing part, and further a first valve and a second valve. The first, second and third housing parts are assembled together along a first directional axis of the second housing part. The first valve and the second valve are held by the first and third housing parts. The second valve is arranged laterally in a spaced-apart relation with respect to the first valve. A fuel vapor flow passage is constituted in such a way that fuel vapor flows from the first valve toward the second valve to cause the entire height of the vent valve assembly to become low.</p> |
