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 body 5A for a connector includes: a head 21a having a plug 22 and a leg part 32a having a first leg 31a which is arranged to allow the centroid of the shape of a continuity part from one end surface 24 in the head 21a not to be positioned on the axial line Ch of the head 21a, and a support leg 33a which is arranged on the downstream side of the first leg 31a and having an axial line Cs different from those of the first leg 31a and the head 21a. The connector 1 includes: a connector tube 4 having connection ports 12-14, a flow passage 15 for the communication of the ports, and a valving element storage part 16 adjacent to the connection ports 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 plug 22 seals the connection port 12 and a second posture where the leg 31a is bent by pressure to be actuated in the axial line Ch direction thereby to allow the inner cavity 81a of a tubular body 81 to communicate with the 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】栓部22を有する頭部21aと、頭部21aの一端面24との連設部形状の重心が頭部21aの軸線Ch上に位置しないように配置された第1脚部31a、及び第1脚部31aの下流側に配置され、第1脚部31a及び頭部21aと異なる軸線Csを持つ支持脚部33aを有する脚部32aとを備えてなるコネクタ用弁体5A、並びに接続口12~14、これらを連通する流路15及び接続口12に隣接する弁体収納部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22が接続口12を密閉する第1姿勢と、軸線Ch方向に作用する圧力で脚部31aが湾曲して管体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3
