The utility model provides an electric wire taking-out structure. When an 'O' shaped sealing ring (4) and a flat washer (5) are inserted through an electric wire, a tongue-shaped protrusion retainer ring (6) is pressed into the electric wire. An internal diameter side protrusion (61) of the tongue-shaped protrusion retainer ring is engaged into an electric wire jacket (22). A CR-shaped retainer ring (7) is inserted through the electric wire. The 'O' shaped sealing ring is embedded into a first cylindrical concave part (32) of a housing (1), and a tongue-shaped protrusion (63) of the tongue-shaped protrusion retainer ring is embedded with a groove part of a second cylindrical concave part (33) by pressing the flat washer and the tongue-shaped protrusion retainer ring, and moreover an elastic clamping claw part of the CR-shaped retainer ring is bitten with the inner circumference of the second cylindrical concave part (33). According to the utility model, in the electric wire taking-out structure by which the electric wire to be connected with a circuit in the housing is fixed on the housing, all the functions such as protection of the electric wire along the drawing-out direction, the pressing-in direction and the rotating direction in respect to the electric wire, and the sealing of the electric wire, are realized by the simple structure.
