PROBLEM TO BE SOLVED: To utilize vacuum pressure to safely connect an instrument 12 for a vacuum device to a vacuum device.SOLUTION: An instrument 12 for a vacuum device has a female pipe joint part detachably connected to a male pipe joint part 10 of a vacuum device. The female pipe joint part has: a cylindrical body 14 fitted into the male pipe joint part 10; a locking element 16 configured to lock the cylindrical body 14 to the male pipe joint part 10; an engagement element 42 configured to, when vacuum pressure is applied, be displaced by outside pressure, and inhibit a locking element constraint member 20 fixing the locking element 16 at a locking position from being displaced; and a locking securement member 30 comprising a pressure receiving displacement member 32.SELECTED DRAWING: Figure 1
【課題】真空圧を利用し真空装置用器具12を安全に真空装置に連結する。【解決手段】真空装置用器具12は真空装置の雄型管継手部10に取り外し自在に連結される雌型管継手部を有する。該雌型管継手部は、雄型管継手部10に嵌合される筒状体14と、該筒状体14を雄型管継手部10に施錠する施錠子16と、真空圧がかけられているときは、外気圧により変位されて、施錠子16を施錠位置にしている施錠子拘束部材20が変位するのを阻止するための係合子42、受圧変位部材32からなる施錠確保部材30とを有する。【選択図】図1
