INDUSTRIAL ROBOT

摘要

A cable drawn from a lower arm of a robot into a first upper arm part of an upper arm is further drawn out to an exterior space of the robot through a first hole of a second upper arm part. The cable is drawn in contact with a sidewall part of the second upper arm part, and is disposed in a wrist arrangement portion through a second hole. A slack part is formed taking account of a length of the cable pulled by a wrist when the wrist pivots in the wrist arrangement portion, and the cable is drawn to a tool through a through hole of the wrist.
