Abstract
In the invention, the structure of an articulated robot is a hollow structure, and the entire body of the arms and closing cover is formed as an enclosed structure. Therefore, an air flow communication passage is maintained, so that dust formed in the robot can be discharged outside of the clean room. Moreover, by forming two or more openings, the pressure level in the robot can be controlled, and without causing adverse effects on the speed reducer or bearing in the slide parts of the articulated robot, it is possible to prevent dust particles of the slide parts generated during operation of the arm, or volatile vapor of lubricant, from flowing out of the robot body.
