摘要

A robot wrist of an industrial robot having a wrist housing supporting two orthogonally arranged rotating output shafts therein, each of the shafts being connected to a robot hand, and a built-in fluid conveying means provided for distributing pressurized air introduced from the outside of the robot wrist toward the robot hand attached to one of the rotating cutput shafts. An output end of each of the two rotating output shafts may either be plugged by a plug element or closed by a stop valve when the output end is not connected to the robot hand.
