ABSTRACT:
A swiveling apparatus has installed electric cables which electrically interconnect equipment in a factory to equipment which is supported by the apparatus. The apparatus includes a fixed part which contains a cylindrical portion which is engaged via bearings with a rotating portion of a rotating part. A plurality of right-hand wound springs and left-hand wound springs are alternately disposed along a periphery of the cylindrical portion of the fixed part and extend between ribs and a base portion of the fixed part. A plurality of electric cables extend between a connector, which is connected to electric cables of the outside equipment, and the equipment which is supported by the rotating part. The springs are of sufficient length so that the rotating part can be rotated through a predetermined angle.
