PROBLEM TO BE SOLVED: To provide a valve body for a connector for demonstrating excellent bending and sealability even when fluid is injected by two or more times, and to provide the connector for demonstrating excellent injection property and sealability.SOLUTION: The valve body 5A for the connector includes: a head part 21 with a plug part 21a and a self curve deformation part 22a extended from one end face of the head part 21 along the axial direction of the head part 21, provided with a groove 24 opened to the outer surface, and curved in one radial direction by a pressure acting in the direction of an axis C. The connector 1 includes: a connector pipe 4 having at least two connection ports 12-14 to which a pipe body 81 can be connected, a flow path 15 for communicating the connection ports 12-14, and a valve body storage part 16 arranged so as to be adjacent to the connection prot 12 and the valve body 5A for the connector stored in the valve body storage part 16, and is shiftable to a first posture in which the plug part 21a seals the connection port 12, and a second posture in which the self curve deformation part 22a is curved in one radial direction by the pressure acting in the direction of the axis C to communicate the lumen of the tube body 81 and the flow path 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、及び、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21aを有する頭部21と、頭部21の一端面から頭部21の軸線方向に沿って伸びると共に、外面に開口する溝24を有して軸線C方向に作用する圧力で一半径方向に湾曲する自己湾曲変形部22a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自己湾曲変形部22a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4
