Title: Industrial robot
Inventor: SHIMA SHINICHI
IPC: B25J19/00
Filed: 1989-02-20
Abstract: PURPOSE:To generate no rubbing on a cable and to effectively prevent the damage accident of the cable by providing a cable guide part rotatable freely inside a revolving drive part and storing it by winding the cable thereon. CONSTITUTION:When a revolving base 4 is revolved in the direction a cable 14 is winding on a cable guide part 22, the cable 14 is fastened to the cable guide part 22 and the force acting in the peripheral direction to the cable guide part 22 is absorbed by the rotation of the cable guide part 22. Thus the cable 14 is not slid with the cable guide part 22 and no rubbing is generated between both the 14 and 22. Consequently, the damage of the cable 14 is prevented.
