Claim:
A suspended robot system comprising: a base suspended from a substantially straight rail movably in both ways along with the rail; a main robot body having an arm arranged rotatably on the base; a flexible cable protecting means bent horizontally in a middle portion thereof in which one end is connected with the rail while another end is connected with the main robot body; and a plurality of cables, which connect between a fixed apparatus and the main robot body, passing through within the flexible cable protecting means; wherein a plurality of cables are unified into a parallel state to constitute a flat cable, and the flat cable is accommodated in the flexible cable protecting means by arranging the cables in a vertical direction, both upper and lower surfaces of an accommodated portion of the flat cable in the flexible cable protecting means are kept away from touching either of upper or lower internal surfaces of the flexible cable protecting means by a floating means, and both ends of the flat cable accommodated in the flexible cable protecting means are fixed to the rail and the main robot body in a state where the floating means slants up both ends of the flat cable so that the upper surface of the accommodated portion of the flat cable does not touch an upper inside surface of the flexible cable protecting means, and the lower surface of the accommodated portion of the flat cable is floated from a lower inside surface of the flexible cable protecting means.
