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 at least one high-expansion/contraction support part 23 that connects the valve body 21 and the support body 22 and supports the valve body 21 and at least one low-expansion/contraction support part 24 that connects the valve body 21 and the support body 22 at a position distal to the seal part 31 with respect to the high-expansion/contraction part 23 in the axial direction of the valve body 21 and apart from the high-expansion/contraction support part 23, and that supports the valve body 21. 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 the connection ports 12-15.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及び支持体22を連結し、弁本体21を支持する少なくとも1つの高伸縮性支持部23と、弁本体21の軸線方向においてシール部31に対して高伸縮性支持部23よりも遠位で高伸縮性支持部23と離間した位置で弁本体21及び支持体22を連結し、弁本体21を支持する少なくとも1つの低伸縮性支持部24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
