PROBLEM TO BE SOLVED: To provide a valve device for a noise eliminator, capable of restricting resonance in parts, and preventing generation of noise. SOLUTION: This valve device 4 for a noise eliminator is installed on a separator in the noise eliminator for opening an opening part as a bypass passage for exhaust gas when exhaust pressure rises to a prescribed pressure. It is provided with a valve seat part 42c having a valve hole 41 to which exhaust gas flows, a plate valve 43 to open/close the valve hole 41, with a base end part 43a fixed to one end side 42a of the valve seat part 42c, and a stopper member 46 to regulate the opening of the plate valve 43. On the valve seat part 42, it is extended from an end surface on the other end side 42h to form a support part 42e and a retainer part 42g. The stopper part 46 is fixed to one end side 42a of the valve seat part 42c at a base end part 42a, and to the retainer part 42g at a tip part 46c. The plate valve 35 is abutted on the stopper part 46e to prevent excess flexure of the plate valve 43. COPYRIGHT: (C)2006,JPO&NCIPI
