<p>[PROBLEMS] To prevent application of an excessive pressure on a downstream side. [MEANS FOR SOLVING PROBLEMS] A fluid pressure adjuster (19) is attached at an intermediate section of an air flow path for adjusting a pressure on the downstream side of the intermediate section to be reduced from that on the upstream side. The fluid pressure adjuster is provided with a relay path (21) attached at the intermediate section to relay air from the upstream side to the downstream side; a flow volume reducing means (11) for reducing a flow volume of the air in the relay path (21); and an air outlet hole (14) provided on the downstream side of the flow volume reducing means (11) in the relay path (21) for communicating inside and outside the relay path (21). The air flow can be controlled by covering the air outlet hole with a finger (9) against the air pressure to suppress or stop the air flowing out from the hole (14) , and by removing the finger (9) from the air outlet hole (14) to release the air from the hole.</p> |
