摘要

PROBLEM TO BE SOLVED: To prevent cables and pipes between a robot arm and a wrist at a top end part from being exposed externally by connecting a robot wrist between the top end branched parts of a robot arm so that it can be rotated through a joint and freely around a horizontal axis line. SOLUTION: After arranged inside the storing part 48 of a robot arm 22, cables 42 and tubes are inserted into a wiring and piping pass 47 formed at the center of a rotating shaft 46 along the center axis as of the rotating shaft 46 of a wrist 26 so that torsion and elongation due to a rotation can be avoided. Also the cables 42 and pipes and connectors 36 passed through the inside of the wrist 26 are fixed to a prescribed position by a cable and pipe fixing means 51.
