Abstract:
    An object of the present invention is to prevent the entanglement of wires upon pulling out a wire in a terminal inserting process. A rubber plug 8 according to the present invention has a tubular main portion 8A, through which a wire inserting hole 5 into which a wire W is inserted along a central axis line C penetrates, and includes an inner lip portion 13 and an outer lip portion 14 having lips 12 circumferentially formed on the inner and outer circumferential surfaces of the main portion 8A and an entanglement preventing portion 8B projecting backward from the rear end of the main portion 8A. Since the entanglement preventing portion 8B has a tapered surface 16 from an opening edge portion 17 of the wire insertion hole 5 to a rear peripheral edge 13A of the outer lip portion 13, even if another wire W touches upon pulling out a wire W from a bundle of wires in a terminal inserting process, this wire W slides on the tapered surface 16 to avoid the entanglement.
