Silencer

A silencer for causing a reduction in exhaust noises of a pressure fluid exhausted from a fluid pressure device, comprising:

• a main body portion to which said fluid pressure device is connected and to which a pressure fluid from said fluid pressure device is introduced;
• a sound absorber retained within said main body portion and formed from filters made up of plural stacked layers having different opening areas;
• and
• a flow adjustment mechanism for gradually increasing a flow amount of the pressure fluid exhausted to the outside from said main body portion through said sound absorber in a direction separating away from said fluid pressure device, wherein the opening areas of said filters are set so as to become gradually smaller directed from an upstream side formed at a side of said main body portion toward a downstream side formed at an exterior side of said sound absorber.
