摘要：
PROBLEM TO BE SOLVED: To provide a syringe which is easily and clearly operable.SOLUTION: The syringe has: a housing 52； a container 34 for receiving injection solution 32 that is connectable to the housing； graduated tube members 66, 88 which are relatively rotatable with respect to the housing but unslidable in an axial direction； a male screw disposed in the graduated tube members； and a sleeve-shaped member 116 which is movable in the axial direction in the housing but is relatively unrotatable with respect to the housing, and has a female screw screwed with the male screw in the graduated tube members. The syringe has a joint mechanism K1 which adjusts axial direction slide of the sleeve-shaped member and injection rate according to the slide in the housing by relative rotation of the graduated tube members with respect to the housing and, moreover, is engaged with the sleeve-shaped member in the injection process and is separable from the sleeve-shaped member for prior selection of desired injection rate.【課題】容易かつ明快に操作可能な注射器を提供する。【解決手段】注射器は、ハウジング５２と；注射液３２を受容するための容器３４であって、かつ、前記ハウジングに結合可能である容器と；前記ハウジングに対し相対的に回転可能であるが軸線方向に摺動不能に構成された配量部材６６，８８と；前記配量部材に配された雄ネジと；前記ハウジング内において軸線方向に可動であるが該ハウジングに対し相対的に回転不能に構成され、かつ、前記配量部材の雄ネジと螺合する雌ネジを有するスリーブ状部材１１６と、を有し、かくして、前記ハウジングに対し相対的な前記配量部材の回転によって、該ハウジング内における前記スリーブ状部材の軸線方向摺動及び該摺動による注入量の調節が可能にされ；更に、注入過程中、前記スリーブ状部材と係合し、かつ、所望の注入量の事前選択のために前記スリーブ状部材から分離可能な結合機構Ｋ１を有する。【選択図】図２
