1. A connector comprising:
a terminal metal fitting attached to an end of a wire;
a housing having a fitting part that accommodates the terminal metal fitting inside thereof and that is inserted and fitted into a counterpart fitting part with a bore shape of a counterpart wall body;
a shield shell including a cylindrical part that covers, from outside, a protruding portion of the housing that protrudes from the counterpart fitting part on an opposite side of an insertion direction of the fitting part to the counterpart fitting part, and a shell flange part that protrudes outward beyond a first outer peripheral surface of the cylindrical part and is disposed opposite a wall surface of the counterpart wall body with an interval therebetween;
a first watertight member with an annular shape that is attached to an outer peripheral wall surface of the fitting part and covers a cylindrical gap between the fitting part and the counterpart fitting part in a fitting state where the fitting part is inserted and fitted into the counterpart fitting part; and
a second watertight member with an annular shape that is crushed between the shell flange part and the wall surface of the counterpart wall body when in the fitting state, wherein
the housing has a housing flange part that is interposed between the shell flange part and the wall surface of the counterpart wall body when in the fitting state, and a second outer peripheral surface is disposed inside an outer edge of the shell flange part and outside an inner edge of the shell flange part,
the housing flange part has a contact surface with an annular shape that contacts the wall surface of the counterpart wall body when in the fitting state,
the second watertight member is disposed outside of the housing flange part and has an inner peripheral surface disposed opposite the second outer peripheral surface of the housing flange part and a pressurized surface with an annular shape that protrudes to the insertion direction side beyond the contact surface of the housing flange part and is subjected to a pressing force from the wall surface of the counterpart wall body when in the fitting state, and
the second watertight member is attached to the shell flange part.
