Abstract

An electrical wire guiding apparatus 10 includes a plurality of link members 20 that are pivotably connected in series, and each have an accommodation space 25 for an electric wire W provided therein. Each of the plurality of link members 20 includes a link body 20A in which a surface positioned on an inner side of a bend in a pivoted state is open as an opening surface 20C, and a cover 20B that is engaged with the link body 20A, and blocks the opening surface 20C.

First claim

What is claimed is:

1. An electrical wire guiding apparatus comprising:
a plurality of links that are pivotably connected in series, and have accommodation spaces for an electric wire provided therein,
wherein each of the plurality of links includes:
a link body in which a surface positioned on an inner side of a bend is open as an opening surface in a pivoted state, and
a cover that includes a pair of engaging protrusions provided at both ends of the cover and is engaged with the link body, and blocks the opening surface using the pair of engaging protrusions, and
wherein each of the pair of engaging protrusions includes a pair of inclined surfaces that are provided at front and rear ends of one of the pair of engaging protrusions when viewed from a side.

2. The electrical wire guiding apparatus according to claim 1 ,
wherein adjacent link bodies among the plurality of links come into contact with each other in the pivoted state, thereby limiting a bending angle relative to each other, and
regarding the cover of each of the plurality of links is disposed at a position at which the cover does not come into contact with an adjacent link in a state where the bending angle is limited.

3. The electrical wire guiding apparatus according to claim 1 ,
wherein adjacent link bodies among the plurality of links are configured to come into a surface contact with each other in the pivoted state.

4. The electrical wire guiding apparatus according to claim 2 ,
wherein each of the pair of inclined surfaces is inclined in an inclination direction corresponding to the bending angle so as to separate from an adjacent link body.

5. The electrical wire guiding apparatus according to claim 1 , wherein the pair of inclined surfaces are inclined toward a leading end of one of the pair of engaging protrusions so as to shorten a distance between the pair of inclined surfaces.
