Inside the retainer the guide possible cable bear device is offered low with wear. Connecting two link plates (3) at specified interval, becomes the link component which (2) is connected revolution possibly mutually, when being moved to longitudinal direction front and back, each link component (2) is connected rectilinear the top and bottom strand where (6 and 8) with, each link component (2) specified angle is bent the reversal zone which (7) is formed, at least several link components (2) in the link plate (3), when the link component is a rectilinear position as to outside, it is extended it is bent in specified angle when being the position where in order not to be extended to outside, moves the support element whichWe were formed, the adjusting device which is made to extend support element (9) according to the relative position relationship of the link component in the link component which it adjoins (11) we formed.
