Inner lips 35 of the rubber stopper 30 fit resiliently with outer circumference faces of the electric wires 20, thereby sealing each cavity 16. A ring-shaped groove 37 is formed concentrically around each electric wire through hole 33 at a posterior face of the rubber stopper 30. Inner portions of these grooves 37 form comparatively thin cylindrical members 38, these fitting tightly with the outer circumference of the electric wires 20.
