Abstract
A swivel joint that is placed between a working device and a forwardly/reversely rotatable wrist section provided on a body section of an industrial robot and has a fluid transmission route for interconnecting the wrist section side and the working device side. The fluid transmission route is a hose, and between the wrist section and the working device, the hose is loosely spirally wound with a margin around a shaft section that rotates together with the wrist section. One end of the hose is non-rotatably fixed to the shaft section, and the other end is fixed so as to be movable with movement of the shaft section.
