a small outer diameter the wire core splice portion 14 b can be fixed without shift in the vicinity of the center in the protective cap 30 accordingly vibrations impacts and the like applied to the protective cap 30 can be mitigated uniformly in all directions so that the problem of being susceptible to vibrations impacts and the like from a certain direction can be solved note that similar effects can be expected by adjusting the thickness of the cushioning member 20 instead of the length of the cushioning member 20 that is to say when sharing the protective cap 30 the cushioning member 20 is made thinner in the case of the electrical wire portion 10 a having a large outer diameter and the cushioning member 20 is made thicker in the case of the electrical wire portion 10 b having a small outer diameter so that the number of times that the cushioning member 20 has to be wound can be the same for the electrical wire portions 10 a and 10 b having different outer diameters next the procedure for assembling the splice 1 for gathering ends according to this embodiment will be described as shown in fig3 a when performing splicing by gathering ends of the plurality of electrical wires 11 the insulating cover members 12 at ends of the electrical wires 11 in the electrical wire portion 10 are cut off so that the wire cores 13 are exposed the exposed wire cores 13 are welded to each.
