To provide a mouthpiece which eliminates the risk where compressed air leaks into atmospheric air, by configuring the mouthpiece to open an operation valve successively after securing an airtight state.SOLUTION: A mouthpiece comprises: a mouthpiece body part 2 consisting of a cylindrical member in which an air supply device is connected at one end side and a tire valve 50 is connected at the other end side; a tire valve insertion hole 3 in a distal end of the mouthpiece body part 2 closer to the tire valve; an O ring 4 which is provided within the tire valve insertion hole 3 closer to the air supply device; a backup ring 5 which presses the O ring 4 from the side of the air supply device of the O ring 4; an actuation body 7 which is formed substantially in a protrusive shape obtained by reducing a diameter of a distal end of a columnar shape, and of which the distal end is inserted through a backup ring center circle 6; openings 5a and 7a to be passages of compressed air in the actuation body 7 and the backup ring 5; a valve opening regulation spring 8 which is disposed between the actuation body 7 and the backup ring 5; and an actuation valve 9 which is built in closer to the air supply device side than the actuation body 7.SELECTED DRAWING: Figure 1

    【課題】気密状態を確保した後に作動バルブが開く順番となる構成とすることで、圧縮空気が大気中に漏れ出る恐れがない口金を提供する。【解決手段】一端側に空気供給装置が接続され、他端側にタイヤバルブ50が接続される筒状部材から成る口金本体部2と、その口金本体部2のタイヤバルブ側先端部にはタイヤバルブ挿入孔3と、そのタイヤバルブ挿入孔3の空気供給装置側に内設されたOリング4と、そのOリング4の空気供給装置側より、そのOリング4を押圧するバックアップリング5と、円柱形状の先端部を縮径された略凸形状から成り、バックアップリング中心円6に先端部が挿通された作動体7と、その作動体7とバックアップリング5には其々圧縮空気の通路となる開口部5a,7aと、作動体7とバックアップリング5との間に配設される開弁調整スプリング8と、作動体7より空気供給装置側に内蔵された作動弁9の構成からなる。【選択図】図1
