- 相手側筒状部材の雄ネジ状接続部が軸線方向に挿抜される筒状の継手本体と、内面に雌ネジ部が形成され、その雌ネジ部を前記雄ネジ状接続部へ係合させる係合位置と前記雄ネジ状接続部から解離させる解除位置との間で変位する係止片とを備えてなり、
前記係止片が前記係合位置に変位することにより前記相手側筒状部材との接続状態に保持されるとともに、前記係止片が前記解除位置に変位することにより前記雄ネジ状接続部の軸線方向への挿抜を可能とするものであって、
前記係止片は、前記継手本体に形成した軸線と前方方向に鈍角をなす傾斜面をもつ切欠部内に収容されるとともに、この切欠部内の前記傾斜面に摺接しつつ前記係合位置と前記解除位置との間での前記傾斜面の傾斜方向への移動を可能とする前傾斜面と、該前傾斜面と背向し後方方向に鈍角をなす後傾斜面とをもち、
前記係止片の前記後傾斜面に摺接する後方方向に鈍角をなす傾斜面をもち、前記係止片を前記切欠部内の傾斜面に摺接させつつ前方上方に押動する前方に付勢されたプッシャーと、
前記雄ネジ状接続部の前記継手本体への挿入動作に伴い、規制部を軸方向へ変位させつつ前記係止片の外周に対し軸方向の所定領域に亘って宛がうことによりその係止片を前記解除位置側への変位規制状態にロックするロック機構と、
を備えていることを特徴とする管継手。 - 前記切欠部は、前記軸線と直角をなし前記傾斜面と背向する直角壁面をもち、
前記係止片は、前記係合位置に変位したとき前記直角壁面に当接する後端面をもつ請求項1に記載の管継手。
