<P>PROBLEM TO BE SOLVED: To provide a humidifying device capable of suppressing increase of pressure loss in comparison to a conventional one while improving durability and distributivity of a hollow fiber membrane bundle. <P>SOLUTION: The humidifying device 10 has (a) a housing 20 provided with a gas introducing part 23 introducing gas G2 into an interior, (b) a hollow fiber membrane module 50 provided with a case 30 having an inlet hole 31 and the hollow fiber membrane bundle 40, and (c) a direct hit suppressing member 60 provided between the gas introducing part 23 and the inlet hole 31 to suppress direct hitting of a gas flow from the gas introducing part 23 to the hollow fiber membrane bundle 40. The direct hit suppressing member 60 is provided with a first face facing the inlet hole 31, a second face 62 extending from one side of the first face 61 to a gas introducing part 23 side, and a third face 63 extending from another side of the first face 61 to the gas introducing part 23 side. An interval between the second face 62 and the third face 63 is gradually reduced as it approaches the gas introducing part 23. <P>COPYRIGHT: (C)2008,JPO&INPIT |
