VENT VALVE
To provide a vent valve capable of reducing force in a case where a lid is added to impact, to prevent damage and protect a valve mechanism, thereby maintaining normal opening/closing operation.SOLUTION: A vent valve comprises: a valve mechanism part 10 configured to reduce internal negative pressure with opening/closing of a valve body 16; a plurality of columnar parts 20 provided at an upper part of the valve mechanism part 10, and forming a ventilation passage 21 for the valve mechanism part 10; and a lid member 15 provided above the ventilation passage 21, and covering the valve mechanism part 10, wherein the lid member 15 is arranged detachably and rotatably with respect to the columnar part 20.SELECTED DRAWING: Figure 1
【課題】蓋に衝撃が加わったときの力を緩和して破損を防止し、弁機構を保護して正常な開閉動作を維持できる通気弁を提供する。【解決手段】弁体１６の開閉により内部の負圧を緩和する弁機構部１０と、この弁機構部１０の上部に設けられて当該弁機構部１０への通気路２１を形成する複数の柱状部２０と、通気路２１の上方に配置されて弁機構部１０を覆う蓋部材１５とを有し、蓋部材１５が柱状部２０に対して着脱且つ回転自在な状態で配置されている。【選択図】図１
