Abstract
A dust-free industrial robot of high performance includes an internal air space substantially closed by arms, articulation members, bearings or covers or a combination thereof in a manner to separate the rotating, sliding and contacting portions of structural elements such as the arms, articulation members, bearings and a drive source from the outside air. The air pressure in the internal air space is made lower than that of the outside air to prevent dust produced during the operation of the robot from being scattered to the outside air.
