PROBLEM TO BE SOLVED: To suppress bedewing water from flowing into a cabin in an oxygen-enriched air feeder for a vehicle. SOLUTION: When a vacuum pump 120 reduces an air pressure in an oxygen enrichment unit 110 through a duct 130, the oxygen-enriched air is produced in the oxygen enrichment unit 110 by preferentially introducing oxygen of external air, is fed through the duct 130, the vacuum pump 120 and a duct 140 and is blown out from a blowing port 150 toward an occupant in the cabin through a duct 130, the vacuum pump 120 and a duct 140. Even if the inside of the cabin is cooled, since a cylindrical heat insulation material 210 is provided on the duct 140 so as to cover the outer periphery thereof, cold can be suppressed from being transmitted from the inside of the cabin into the duct 140 through an interior member 230. Accompanying with this, since the oxygen-enriched air of the duct 140 can be suppressed from being cooled, bedewing water can be suppressed from being generated in the duct 140.
