PROBLEM TO BE SOLVED: To provide a female connector to which rotational torque is easily applied.SOLUTION: The female connector includes a pair of grip parts 55 provided on the outer peripheral surface an insertion part 41 into which a tubular part of a male connector is inserted and a pair of projections 62 engaged with a pair of engaging claws of the male connector. In a state of the tubular part being inserted in the insertion part, the pair of grip parts are rotated relative to the male connector. The pair of projections can thereby be engaged with the pair of engaging claws or released from the engagement. The pair of projections are arranged on a major axis 59a where the outer dimension of the female connector is maximum when viewed along a direction parallel with a center axis of the insertion part, and the pair of grip parts are arranged on a minor axis 59b orthogonal to the major axis. In a position in the direction of the center axis where the pair of grip parts are arranged, the outer dimension in the major axis direction of the outer peripheral surface is greater than the outer dimension in the minor axis direction of the outer peripheral surface.COPYRIGHT: (C)2012,JPO&INPIT【課題】回転トルクを印加しやすいメス型コネクタを提供する。【解決手段】メス型コネクタは、その外周面上に設けられた一対の把持部55と、オス型コネクタの管状部が挿入される挿入部41と、オス型コネクタの一対の係合爪と係合する一対の凸部62とを備える。挿入部に管状部を挿入した状態でオス型コネクタに対して一対の把持部を回転させることにより、一対の凸部を一対の係合爪に係合させ又はその係合を解除することができる。挿入部の中心軸と平行な方向に沿って見たとき、メス型コネクタの外寸法が最大となる長軸59a上に一対の凸部が配置されており、長軸と直交する短軸59b上に一対の把持部が配置されている。一対の把持部が配置された中心軸方向の位置において、外周面の長軸方向の外寸法は、外周面の短軸方向の外寸法よりも大きい。【選択図】図1
