PROBLEM TO BE SOLVED: To provide the bearing set which can give the uniform and stable pre-load a top foil. SOLUTION: The hydrodynamic pressure bearing set 170 used with the thrust disk 11, which is arranged between the plane faces of a housing, has the first and the second annular top foil 121, 122 fixed detachably to the housing which is adjoined and arranged respectively to the bearing face of an axial direction in both sides of the thrust disk 11. The first and the second under springs 25, 27 are fixed respectively between each of the plane housing faces and the first and the second annular top foil 121, 122. The separation spring 171 which has a larger inside diameter than the outside diameter of the thrust disk 11 contacts to both faces of the first and the second annular top foil 121, 122 which is trying to separate the foil 121, 122 respectively from the axial direction bearing face in both faces of the thrust disk 11.
