PROBLEM TO BE SOLVED: To provide the screw locking connecting in which the tapered surface of a male lure and the tapered surface of a female luer are always adhered appropriately, and the slack of screwing of an external thread and a female screw is inhibited.SOLUTION: The medical use knife connector 50 includes: a tube 51 in which a tapered surface 22 of a male lure 20 is inserted an external thread 53 which is screwed with a female screw 32 of a lock nut 30, and is formed at the outer peripheral surface of a tube and a pair of grip arms 60 which has been arranged so that the tube may be inserted, and can be rocked in elasticity. An engagement structure 62 which engages with the lock nut is formed at each end of the pair of grip arms.COPYRIGHT: (C)2012,JPO&INPIT【課題】ネジロック接続において、雄ルアーのテーパ面と雌ルアーのテーパ面とを常に適切に密着させ、且つ、雄ネジと雌ネジとの螺合の緩みを防止する。【解決手段】医療用メスコネクタ50は、雄ルアー20のテーパ面22が挿入される筒状部51と、ロックナット30の雌ネジ32と螺合する、筒状部の外周面に形成された雄ネジ53と、筒状部を挟むように配置された、弾性的に揺動可能な一対のグリップアーム60とを備える。一対のグリップアームのそれぞれの一端に、ロックナットに係合する係合構造62が設けられている。【選択図】図2
