Zusammenfassung:	PURPOSE: To provide a high performance bearing metal variable phase-type bearing for exhibiting oil film properties most suitable for vibrational properties of a rotary shaft, and achieving stability of a shaft system through a process of changing the critical speed and unbalanced response characteristics in relation to the change of the operational condition of the rotary shaft. CONSTITUTION: A bearing metal 03 is inserted into a bearing housing 10 so as to be turned around its axis. In a slide bearing such as a cylindrical bearing, two circular-arc bearing, and a tilting pad bearing provided with a structure for rotating the bearing metal 03 to the optional phase in the circumferential direction, teeth 05 notched on a part of the outer periphery or on the whole periphery of the bearing metal 03 and a phase adjusting means 06 of the bearing metal 03 supported to the bearing housing 10, and on which teeth to be meshed with the teeth 05 of the bearing metal 05 are projectingly provided are provided.
