The covering 11b is made of, for example, a tubular insulating material made of a resin (synthetic resin) mainly composed of polyvinyl chloride or polyethylene.

  The electric wire bundle 12 is obtained by bundling a plurality of electric wires 11 at a predetermined interval with, for example, an insulating tape, or by roughly winding an insulating tape in a spiral shape and then covering a corrugated tube 14 with a specific length section. .

  The protector 13 is made of, for example, a synthetic resin such as polypropylene or nylon resin. The protector body 33 has a concave cross-sectional shape, for example, a flat, substantially U-shaped cross-sectional shape, and a wire bundle together with the protector main body 33. 12 and a lid member 35 that forms a predetermined length of the wire through-hole 34 (see FIG. 2) that penetrates the wire 12.

  The protector 23 is configured in the same manner as the protector 13 at least at a portion where the corrugated tube 14 is coupled so as to be prevented from being detached. For example, the protector 23 is exactly the same as the protector 13. Therefore, the detailed configuration of the protector 23 is the same as the detailed configuration of the protector 13 described below.

  The protector main body 33 is configured such that the protector main body 33 and the lid member 35 can be integrally coupled by at least one lock mechanism and a hinge coupling portion (not shown) or by a plurality of lock mechanisms.

  The protector body 33 includes a concave inner wall 33a that forms a groove-shaped wire penetration path 34a through which the wire bundle 12 passes, an opening end 33e that opens at one end of the wire penetration path 34a, and the vicinity of the opening end 33e. Thus, it has a retaining holder 36 that retains and retains the corrugated tube 14 sheathed on the wire bundle 12.

  The retaining holder 36 has a concave / convex engaging portion 41 and a concave / convex engaging portion 43 that engage with the outer peripheral portion of the corrugated tube 14.
