PURPOSE:To permit the stable high-speed revolution by arranging the pockets with the phase shifted in the circumferential direction between rows and offsetting the reaction force in the direction perpendicular to the direction of eccentricity between the pockets in each row. CONSTITUTION:Pressurized oil flows into the pockets 10-12 in each row through oil feeding holes 13-15, and a rotary shaft is supported by the pressurized oil. In this case, the pockets 10-12 between the pocket rows 10a-12a shift in the circumferential direction. Therefore, when shaft is set eccentric in the radial direction, the reaction force in the radial direction which is perpendicular to the above-described radial direction is offset between the pocket rows 10a-12a, and the reaction force is directed nearly in the radial direction in the initial state. Therefore, the stability of a bearing 9 can be improved markedly, and high speed revolution is permitted.
