PROBLEM TO BE SOLVED: To provide a valving element for a connector, which shows an excellent bending property and sealing property even when the injection of a fluid is performed a plurality of times, and also to provide a connector which shows excellent injection and sealing properties.SOLUTION: The valving element 5A for a connector includes: a head 21 a solid bottom 22 arranged on the downstream side extension line of the head 21 and a self bending and deformation part 23A disposed between the head 21 and the bottom 22 and to be bent in one radial direction by pressure to be actuated in an 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 a plug 52 seals the connection port 12 and a second posture where the self bending and deformation part 23A is bent in one radial direction by pressure to be actuated in the axial line C direction thereby to allow the inner cavity of the 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湾曲性及びシール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21と、頭部21の下流側延長線上に配置された中実の底部22と、頭部21と底部22との間に配置され、軸線C方向に作用する圧力によって一半径方向に湾曲する自己湾曲変形部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、栓部21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自己湾曲変形部23Aが一半径方向に湾曲して管体81の内腔と流路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8
