<p>In this cable support structure, at least one cable (14) introduced into a movable body (13), which is provided so that it can be turned relative to a base body (10) about its axis (X), through the interior of the base body (10), which has a cylindrical inner surface (11) is supported in the interior of the base body of an industrial robot. An inner cylinder (15) is provided coaxially in the base body and fixed to the movable body (13). The inner cylinder and base body define an annular space therebetween. Each of resilient belt-like plates (19, 20) is fixed at its one end (21, 30) to the inner surface of the inner surface of the base body, and at the other end (22, 31) thereof to an outer cylindrical surface (16) of the inner cylinder. The plates are bent arcuately at their arbitrary portions so that one side surface of one plate is opposed to that of the other. The plates are pressed against the inner surface of the base body and the outer surface of the inner cylinder due to their own resilient force in an arbitrary position of pivotal movement of the movable body. A plurality of cable holders (25, 32) are provided on one side surface of the plates (19, 20) so that the cable holders are spaced from one another along the longitudinal direction of the plates, the cable holders supporting the cables.</p> |
