スイベルジヨイント。 One of the shaft parts each having a flow path for high-pressure fluid therein and the receiving part into which the shaft part is fitted is fixed, and the other rolls and rotates relative to the one, and the one is rotated from the other to the other. In a high-pressure fluid swivel joint that introduces high-pressure fluid into the interior, a cylindrical space is formed between the shaft portion and the receiving portion at an appropriate location in the direction of the rotation axis, and a cylindrical space is formed between the shaft portion and the receiving portion. A communication passage that communicates with the passageway is provided so as to communicate with one end of the cylindrical space in the direction of the rotation axis, and a communication passage that is slidable in the direction of the rotation axis is provided on the side of the communication passage in the cylindrical space. A swivel joint for high-pressure fluid, characterized in that an annular movable seal body is provided to seal oil and fat in a cavity on the opposite side of the communication path in the cylindrical space.
