Abstract

A wire guide device A includes a wire guide body 15 that is formed by coupling a plurality of link members 17 in series such that the link members 17 can rotate relative to each other, and inside which an accommodation space 16 for a wire W is formed. The link member 17 includes a link body 20 and a lid 31. The link body 20 is provided with an opening 29 through which the accommodation space 16 is open toward the outside of the wire guide body 15. The lid 31 is locked to the link body 20 and thereby closes the opening 29. The openings 29 and the lids 31 are arranged on surfaces of the link members 17 that are located on an inner side of a curved portion of the wire guide body 15 when the wire guide body 15 is curved.

First claim

What is claimed is:

1 . A wire guide device comprising
a wire guide body that is formed by coupling a plurality of link members in series, the link members being capable of rotating relative to each other, and inside which an accommodation space for a wire is formed, wherein the link member includes a link body and a lid, the link body is provided with an opening through which the accommodation space is open toward the outside of the wire guide body, the lid is locked to the link body and thereby closes the opening, and the openings and the lids are arranged on surfaces of the link members that are located on an inner side of a curved portion of the wire guide body when the wire guide body is curved.

2 . The wire guide device according to claim 1 , wherein, when the radius of curvature of the curved wire guide body is the smallest, the adjacent lids are not in contact with each other.

3 . The wire guide device according to claim 1 ,
wherein the link body includes two opposed portions that are arranged opposed to each other with the accommodation space being located therebetween, and a base portion that is coupled to and supports the two opposed portions, and the lid includes locking portions and receiving portions, the locking portions overlap the outer surfaces of the opposed portions, and each of the opposed portion is located between the receiving portion and the locking portion.

4 . The wire guide device according to claim 3 ,
wherein the lid is provided with a step portion formed by recessing the outer side surface of the lid and protruding the inner side surface of the lid, and the receiving portion includes a first supporting portion serving as a portion of the step portion, and a second supporting portion protruding from the inner side surface of the step portion.

5 . The wire guide device according to claim 3 ,
wherein the adjacent link bodies are coupled to each other by stacking the opposed portions of one of the adjacent link bodies on the opposed portions of the other link body in a vertical direction and fitting shaft portions whose axes extend in the vertical direction to bearing holes, groove-like fitting portions are formed in order to fit outer edge portions of the opposed portions of the other link body to the opposed portions of the one link body, and the groove-like fitting portion is located between the locking portion and the receiving portion in a vertical direction.
