Abstract

　継手本体１には、結合部材２と螺合する螺合部が形成され、結合部材２には、継手本体１と螺合する螺合部が形成されている。継手本体１及び結合部材２のうちの何れか一方は雌ねじ筒部１４を有し、他方は軸部２３を有している。雌ねじ筒部１４の内周面には、螺合部としての雌ねじ１４ａが形成され、軸部２３の外周面には、螺合部としての雄ねじ２３ａが形成されている。また、軸部２３において基部２２の側面２２ａと雄ねじ２３ａの基端との間には、雄ねじ２３ａの谷径と同等又はそれより小径の環状溝２４が形成されている。継手本体１と結合部材２との締結により雄ねじ２３ａが雌ねじ筒部１４内に進入し、雄ねじ２３ａの基端が丁度見えなくなったとき、継手本体１と結合部材２との締結が完了する。
