れぞれ構成している。The above-mentioned fitting frame 7 is provided in the screw housing portion 2 so as to surround the retaining ring insertion hole 2b. Further, the upper groove wall 3c 1 of the retaining ring fitting groove 3c of the screw 3 has the notch 4a (see FIG. 7) in a part of the peripheral ring as described above, and the upper retaining surface of the retaining ring 4.
3A, the hole bottom portion 2b 1 of the retaining ring insertion hole 2b constitutes the lower holding surface 2A.
凸部８は、下部保持面2Aである孔底部2b1に、連続する
斜面8aをもつ環状凸部として周設されている。The convex portion 8 is provided around the hole bottom portion 2b 1 which is the lower holding surface 2A as an annular convex portion having a continuous inclined surface 8a.

持力が向上する。Function After the screw 3 is inserted into the screw housing 2 of the female connector housing 1, and the retaining ring 4 is externally inserted from the tip of the threaded portion 3b, the diameter of the retaining ring 4 elastically expands due to the cut 4a. As a result, it is fitted into the retaining ring fitting groove 3c beyond the upper holding surface 3A of the screw 3, and at the same time, the retaining ring 4 elastically returns so that its lower end contacts the slope 8a, and the retaining ring 4 becomes the upper part of the screw 3. It is pressed against the holding surface 3A and its reaction force presses against the slope 8a,
The retaining ring 4 is pushed into the slope 8a and its diameter is narrowed, so that the retaining ring 4 is sandwiched between the upper holding surface 3A and the slope 8a. Therefore, rattling of the retaining ring 4 is eliminated, abnormal noise is prevented from occurring, and the retaining ring 4 is pressed into the retaining ring fitting groove 3c due to the reduction in diameter, so that the retaining force for the screw 3 is improved.
