とする静圧軸受装置。 In a hydrostatic bearing device in which a bearing pocket to which pressurized oil is supplied from the outside is provided between the outer peripheral surface of a spindle and the inner peripheral surface of a bearing member that rotatably supports the spindle, the spindle is provided with a step. a spring having a small outside diameter portion and a large outside diameter portion through which a sealing contact ring is slidably fitted in the bearing member in the axial direction, and presses the contact ring against the stage of the spindle; The contact ring is supported on one end surface of the contact ring, and a pressurized air chamber is formed on the back side of the one end surface of the contact ring within the bearing member, and is moved toward the outer diameter side of the spindle by the pressure oil sent to the bearing pocket side when the spindle rotates. A hydrostatic bearing device characterized in that a push rod is disposed inside the bearing member on the side of the large outer diameter of the spindle, and a tip of the push rod is brought into contact with the other end surface of a contact ring.
