Description will be made based on 0. As shown in FIG. 10, the noise absorbing device 61 of the present embodiment differs from the above embodiments in that the holding case 62 is formed of semi-cylindrical first and second case portions 63 and 64 formed separately. Is formed. The other constructions of the electric wire clamping member 65 and the storage portion 66 are substantially the same as those of the second embodiment, but locking hooks are provided on both sides of the case portions 63 and 64 in order to combine the two case portions 63 and 64. The difference is that a 67 and a locking portion 68 are provided.

造が容易であるという利点がある。With such a structure, the same effects as those of the above-described embodiments can be obtained. However, since the case portions 63 and 64 are separated from each other, even when the number of the electric wires 20 is large, the holding case 62 is checked while confirming the position of the electric wires 20. Can be closed, and the manufacturing is easy.

る。Next, a sixth embodiment will be described with reference to FIG. As shown in FIG. 11, the noise absorbing member 71 of the present embodiment differs from the above embodiments in that the wire clamping member 72 does not have elasticity. That is, the hard wire holding members 72 are provided upright at both ends of the first case portion 73. Even with such a configuration, for example, by closing both the case portions 73 and 75 in a state where the loose wire (electric wire) is fitted into the wire insertion portion 74, the loose wire can be firmly clamped, and the noise absorbing tool 71 itself can be used. Can be fixed firmly to loose wires.
