The present invention relates to a rotary joint comprising a first joint means connected to a body to be rotated, and a second joint means connected to a body that rotates the body to be rotated. The first joint means and the second joint means are connected so as to be movable in the radial direction. According to the present invention, the rotary shaft of the rotary joint is movable so as to buffer the load applied by the rotating structure to which a medium is to be transferred, thus lengthening the service life of the rotary joint. Further, the rotary joint of the present invention may prevent the leakage of fluid and smoothly rotate even when the rotary part of the rotary joint has various shapes, such as a circular shape, an elliptical shape, and a polygonal shape. |
