Abstract
In a waterproof structure of a connector (11), each of a pair of housings (17, 19) has an annular member (51, 81) projecting in a fitting direction. An outer circumferential surface (81a) of one annular member (81) is inclined so as to spread outward in the radial direction from the front end toward the back, and presses the inner circumferential surface of the other annular member (51) at the time of fitting. The curvature of the outer circumferential surface of the plurality of corner parts (109a to 109d) of the annular member (81a) is larger than the curvature of the outer circumferential surface of the other portion, and the inclination angle of the former outer circumferential surface with respect to the fitting direction is larger than the inclination angle with respect to the fitting direction of the latter outer circumferential surface.
