A swivel joint for supplying and discharging various types of fluid between the top and bottom of a rotating platform includes an outer cylinder, an intermediate cylinder, and an inner cylinder that are arranged concentrically around a central axis. The intermediate cylinder can freely rotate with respect to the outer cylinder and the inner cylinder, and a hydraulic fluid flow channel is provided between the outer cylinder and the intermediate cylinder. A hot water flow channel between the lower portion of the inner cylinder and the intermediate cylinder includes an inner annular groove formed on the inner circumferential face of the intermediate cylinder. An air flow channel between the upper portion of the inner cylinder and the intermediate cylinder includes outer annular grooves formed on the outer surface of the inner cylinder.
