A rotary joint which supplies and discharges a liquid to and from a container which is revolved around a rotation axis, the rotary joint comprising: a shaft body which is immovably provided; a tube body into which the shaft body is inserted and which is rotated around the shaft body; a shaft-side supply flow path which is provided in an interior of the shaft body and has an opening provided on an outer peripheral surface of the shaft body; a shaft-side discharge flow path which is provided in the interior of the shaft body and has an opening provided at a different position separated in an axial direction of the shaft body from the opening of the shaft-side supply flow path on the outer peripheral surface of the shaft body; a tube-side supply flow path which is provided to penetrate the tube body from an inner peripheral surface to an outer peripheral surface of the tube body and disposed at a position overlapping the opening of the shaft-side supply flow path in the axial direction of the shaft body; a tube-side discharge flow path which is provided to penetrate the tube body from the inner peripheral surface to the outer peripheral surface of the tube body and disposed at a position overlapping the opening of the shaft-side discharge flow path in the axial direction of the shaft body; a supply communication flow path which is provided in an annular shape around the shaft body between the outer peripheral surface of the shaft body and the inner peripheral surface of the tube body and makes the shaft-side supply flow path and the tube-side supply flow path communicate with each other; and a discharge communication flow path which is provided in an annular shape around the shaft body between the outer peripheral surface of the shaft body and the inner peripheral surface of the tube body and makes the shaft-side discharge flow path and the tube-side discharge flow path communicate with each other, characterized in that the tube-side supply flow path is inclined in a direction opposite to a rotation direction of the tube body with respect to a radial direction which extends to pass through a center of a connection portion between the tube-side supply flow path and the supply communication flow path from the shaft body, and the tube-side discharge flow path is inclined in a same direction as the rotation direction of the tube body with respect to a radial direction which extends to pass through a center of a connection portion between the tube-side discharge flow path and the discharge communication flow path from the shaft body. a shaft body which is immovably provided; a tube body into which the shaft body is inserted and which is rotated around the shaft body; a shaft-side supply flow path which is provided in an interior of the shaft body and has an opening provided on an outer peripheral surface of the shaft body; a shaft-side discharge flow path which is provided in the interior of the shaft body and has an opening provided at a different position separated in an axial direction of the shaft body from the opening of the shaft-side supply flow path on the outer peripheral surface of the shaft body; a tube-side supply flow path which is provided to penetrate the tube body from an inner peripheral surface to an outer peripheral surface of the tube body and disposed at a position overlapping the opening of the shaft-side supply flow path in the axial direction of the shaft body; a tube-side discharge flow path which is provided to penetrate the tube body from the inner peripheral surface to the outer peripheral surface of the tube body and disposed at a position overlapping the opening of the shaft-side discharge flow path in the axial direction of the shaft body; a supply communication flow path which is provided in an annular shape around the shaft body between the outer peripheral surface of the shaft body and the inner peripheral surface of the tube body and makes the shaft-side supply flow path and the tube-side supply flow path communicate with each other; and a discharge communication flow path which is provided in an annular shape around the shaft body between the outer peripheral surface of the shaft body and the inner peripheral surface of the tube body and makes the shaft-side discharge flow path and the tube-side discharge flow path communicate with each other, characterized in that the tube-side supply flow path is inclined in a direction opposite to a rotation direction of the tube body with respect to a radial direction which extends to pass through a center of a connection portion between the tube-side supply flow path and the supply communication flow path from the shaft body, and the tube-side discharge flow path is inclined in a same direction as the rotation direction of the tube body with respect to a radial direction which extends to pass through a center of a connection portion between the tube-side discharge flow path and the discharge communication flow path from the shaft body.
