PROBLEM TO BE SOLVED: To provide a connector having both of sealability by initial sealing and re-sealing properties and injection easiness, and a connector valve element contributing to the sealability and the injection easiness of the connector.SOLUTION: A connector 1 comprises a connector valve element 7 and a connector tube 5. The connector valve element 7 includes a valve body 21 disposed in a first connection port 12 and having an inverse truncated cone-shaped seal part 31 a support body 22 juxtaposed to the valve body 21 apart therefrom and at least one support connection part 23 that is laterally laid across the valve body 21 and the support body 22 in a plane perpendicular to an axis C of the valve body 21 on an area having a central angle of 180° or less, with the axis C used as the center. The connector tube 5 includes: at least two connection ports 12-14 capable of connecting the connector valve element 7 and a tube body and an inner channel 15 that communicates with the connection ports 12-14.COPYRIGHT: (C)2014,JPO&INPIT【課題】初期シール及び再シール性による密閉性と注入容易性とを兼ね備えたコネクタ、並びに、コネクタの密閉性及び注入容易性に貢献するコネクタ用弁体を提供すること。【解決手段】第1の接続口12内に配置される逆錐台形状のシール部31を有する弁本体21と、弁本体21と離間して並設された支持体22と、弁本体21の軸線Cに垂直な平面において軸線Cを中心とする中心角180°未満の領域内で弁本体21及び支持体22に横架された少なくとも1つの支持連結部23とを備えているコネクタ用弁体7、並びに、このコネクタ用弁体7と、管体を接続可能な少なくとも2つの接続口12~14及びこれらの接続口12~14を連通する内部流路15を有するコネクタ管5とを備えたコネクタ1。【選択図】 図1
