Abstract: A rubber stopper for a waterproof connector includes: a first elastic member including a first contact face, and first wire fitting grooves each having an arc cross-section; and a second elastic member including a second contact face and second wire fitting grooves each having an arc cross-section. When the first contact face contacts the second contact face, circular cross-section is formed by the arc cross-sections of the first and second wire fitting grooves to fit wires into the first and second wire fitting grooves. Arc length of the arc cross-section of the first wire fitting groove is different from arc length of the arc cross-section of the second wire fitting groove so that a center of the circular cross-section is disposed away from the first and second contact faces in a direction perpendicular to an extending direction of the first and the second contact faces.
