Claims

[Scope of utility model registration request]

A thrust plate with a smaller diameter than the outer diameter of the rotary table is provided below the rotary table, spaced apart in the axial direction and protruding in the radial direction, and a rotary shaft is protruded from the center of rotation, and a shaft hole that fits into the rotary shaft is provided. A pair of bearing metals having a plurality of hydrostatic pressure bearing pockets formed in the circumferential direction on the circumferential surface are installed on a table support body with vertical separation, and in an annular space formed between the rotary table and the thrust plate, A ring-shaped upper bearing metal having a bearing surface that slides on the top surface of the thrust plate is arranged, and the bearing surface that slides on the bottom surface of the thrust plate is placed in the annular space formed between the bottom surface of the thrust plate and the table support. a ring-shaped lower bearing metal having A rotary table characterized in that pressure fluid supply means for supplying pressure fluid to each of the thrust bearing pockets through a restriction is communicated with each thrust bearing pocket.
