To provide a gas filtering device capable of restraining inconvenience such as an increase in fluid resistance and pulsation of gas caused by displacement of a filtering sheet.
An inlet port is integrally formed in an inlet housing 20, and an outlet port 31 is integrally formed in an outlet housing 30. A filtering chamber 60 is formed of the inlet housing 20 and the outlet housing 30. A capturing element 55 for capturing dust-dirt included in suction air and the filtering sheet 41 adsorbing fuel vapor leaking out of a combustion chamber, are superposably arranged in this filtering chamber 60. The outlet port 31 has an extension part 31b extending to the filtering chamber 60 in the direction parallel to the filtering sheet 41 and opening on its tip. A hardening part 41a is formed in a position corresponding to the extension part 31b in the filtering sheet 41.
