PROBLEM TO BE SOLVED: To provide a valving element for a connector, which shows excellent deformation recovery even when the injection of a fluid is performed more than once, and also to provide a connector which shows an excellent injection property and sealing property.SOLUTION: The valving body 5A for a connector includes: a head 21a a trunk 22a arranged on the downstream side of the head 21a and a continuity part 23a which performs continuity between the head 21a and the trunk 22a and inclines the head 21a in an axial line C direction by pressure to be actuated in the axial line C direction. The connector 1 includes: a connector tube 4 having at least two connection ports 12-14 for connecting a tubular body 81, a flow passage 15 for the communication of the connection ports 12-14, and a valving element storage part 16 arranged to be adjacent to the first connection port 12 and the valving body 5A for the connector, which is stored in the valving element storage part 16. The connector is shifted between a first posture where the head 21a seals the connection port 12 and a second posture where the head 21a is inclined in the axial line C direction by pressure to be actuated in the axial line C direction thereby to allow the inner cavity 81a of a tubular body 81 to communicate with a flow passage 15.COPYRIGHT: (C)2013,JPO&INPIT【課題】流体の注入を複数回行っても優れた変形復元性を発揮するコネクタ用弁体並びに優れた注入性及びシール性を発揮するコネクタを提供すること。【解決手段】頭部21aと、頭部21aの下流側に配置された胴部22aと、頭部21aと胴部22aとを連接し、軸線C方向に作用する圧力によって頭部21aを軸線C方向に対して傾倒させる連接部23aとを有するコネクタ用弁体5A、並びに、管体81を接続可能な少なくとも2つの接続口12~14、接続口12~14を連通する流路15及び第1の接続口12に隣接するように配置された弁体収納部16を有するコネクタ管4と、弁体収納部16に収納されたコネクタ用弁体5Aとを備え、頭部21aが接続口12を密閉する第1姿勢と、軸線C方向に作用する圧力で頭部21aが軸線C方向に対して傾倒して管体81の内腔81aと流路15とを連通させる第2姿勢とに移行可能なコネクタ1。【選択図】 図4
