Abstract

　本発明は、プランジャロッドでピストンを引き出すことにより注射器バレル内に薬液を充填するような引き抜き動作を行う場合であっても、プランジャロッドの先端にピストンを確実に保持して、このピストンをプランジャロッドとともに一体的に引き抜くことが可能な注射器用プランジャアセンブリを提供するものである。 注射器バレル内に摺動自在に挿入されるピストン（４）と、前記ピストンの基端側に開口して形成された凹所（８）内に一端部が挿入されて前記ピストンを一体的に支持するプランジャロッド（６）とから構成され、前記ピストンの凹所は一方面が開口して形成された略円筒状の孔であるとともに、前記プランジャロッドの一端部には、前記ピストンの前記円筒状の孔の内壁に摺接する又はねじ込む雄ネジ（１２）が形成され、この雄ネジが前記凹所内に装入される。
