- 先端部に注出部3を設けた外筒Aと、後端部より外筒A内へ押し込み可能に嵌合したプランジャBとを備え、プランジャBは環状の装着凹部17を備えた本体B1と、装着凹部17の先端部に本体後方への相対移動が可能に内周を嵌合するとともに、外筒A内周に液密摺動可能に外周を嵌合させ、且つ、内周より突設した弾性突片21を本体B1外周に弾性変形可能に嵌着させたシール筒B2とからなり、プランジャB前方の外筒A部分内に流動体を収納させた状態からプランジャBを押し込みすると、弾性突片21が弾性変形して本体B1に遅れてシール筒B2が前進し、プランジャBの押し込み開放で弾性突片21が弾性復元してシール筒B2に対して本体B1が後退する如く構成し、前記弾性突片21が、シール筒B2の内面から内方へ突設したフランジ状をなすとともに、前記装着凹部17の周面に凹設した環状の凹溝18に嵌着したものであり、凹溝18の後端側開口縁部に、中心軸と直交方向である外方に行くに従って広がる切欠き部tを設けたことを特徴とするシリンジ。
- 前記装着凹部17を本体B1前部に設けるとともに、装着凹部17より後方の本体部分を放射板状として外筒A内面への本体B1外面の接触を本体B1外面を形成する複数の線状面fで行った請求項1に記載のシリンジ。
