PURPOSE: An exhaust valve device is provided to effectively prevent contact sound by preventing the sudden movement and shaking of a cap assembly. CONSTITUTION: An exhaust valve device comprises a base(110), a guide shaft(120), a cap assembly(130), and an elastic member(140). The base is fixed to a barrier(200) to be located at a through hole. Exhaust gas is discharged through a discharge hole of the base. The guide shaft is fixed to the base. The cap assembly is installed in the guide shaft and is moved apart from the base. The elastic member supplies elastic restoring force to the cap assembly toward the base.
