PROBLEM TO BE SOLVED: To provide an electric wiring connector enabled to make a seal margin constant when the electric device is connected, and enabled to prevent operation errors such as a permeation of coolant liquid caused by a loosening, or a breaking caused by excessive tightening. SOLUTION: A male terminal surrounding part is formed at the top end of a male connector main body of the electric wiring connector, and a male screw is threaded at the outer periphery of the top end, and a male screw, having a stepped part of with the diameter larger than the male screw is mounted to the rear end. A female terminal having a shoulder facing a ring- shaped top end surface of the male connector surrounding part is formed at the top end of a female connector main body. A ring-shaped female screw having a female screw threaded at its inner periphery is mounted to the female terminal. A ring-shaped sealing, deforming by the pressure between the ring- shaped top end surface and the shoulder when locked, is arranged at the shoulder part. A spacer, pinched between the step part of the male screw and the end surface of the female screw when connected, is formed, and the deformation of the sealing is made so as to keep a prescribed deformation volume by changing the thickness of the spacer.
