PROBLEM TO BE SOLVED: To provide a mechanism for positively preventing occurrence of noise induced under an unstable action of a valve mechanism mounted at a vent tube even under a severe condition of a very high gas flow rate within the vent tube. SOLUTION: There is provided a valve mechanism for a vent tube in which a vent valve body 3 normally closes a vent port 2 and the vent port 2 is released through an increasing of a pressure within a tank. As a vibration attenuation mechanism, there is provided one wire rope 11 between the vent valve body 3 or a member integrally arranged at the vent valve body, its surrounding fixed member, for example, a vent valve supporting member 1.
