<Effect>
In the wire harness 3 provided with the wire protector composed of the wiring tool 1 and the cover member 2, the electric wire 9 is protected by the wiring tool 1 and the cover member 2 arranged so as to sandwich the wire 9. Further, the semi-independent portion 12B formed in a part of the wiring tool 1 is passed through the connection hole 21 of the cover member 2 from the front end side thereof, and further passed through the retaining hole 13B of the wiring tool 1, The wiring tool 1 and the cover member 2 are connected. Thus, since the quasi-isolated portion 12B that connects the wiring tool 1 and the cover member 2 is formed as a part of the wiring tool 1, the number of parts is significantly smaller than the conventional one.

  Further, in the wire protector according to the present invention, since the wiring tool 1 has the guide part 15 formed by vacuum forming, the work of arranging the electric wire 9 along the wiring part 11 becomes easy. Moreover, the apparatus and process which form the guide part 15 by vacuum forming are suitable at the point which can be implement | achieved easily rather than the apparatus and process which shape | mold the resin member which has the guide part protruded by injection molding.

  Further, in the wire protector according to the present invention, the semi-isolated portion 12B is only partially passed through the cover member 2 and the retaining hole 13 of the wiring tool 1, and the wiring tool 1 and the cover are removed by the action of the retaining mechanism. The member 2 is held in a connected state. Therefore, the man-hours and apparatus for attaching the wire protector to the wire 9 are greatly simplified as compared with the prior art. In particular, if the retaining mechanism of the quasi-isolated portion 12B is configured by a hook portion formed in a part of the quasi-isolated portion 12B and the edge portion of the retaining hole 13B, the quasi-isolated portion 12B cannot be removed from the retaining hole 13B. The work for making it so is easy. The retaining hole 123, the overhanging portions 123A and 123B, or the protruding portions 123D and 123E are examples of the hooking portion.

  Further, in the retaining mechanism, the plurality of hanging portions are formed side by side at a plurality of locations along the insertion direction into the retaining hole 13B in the quasi-isolated portion 12B, and therefore are secured from the root portion 121 in the quasi-isolated portion 12B.
