description	PROBLEM TO BE SOLVED: To provide a bearing unit in which optimization of rigidity is achieved and torque is reduced at the same time, while quickly controlling an object to be borne with the bearing and increasing accuracy. SOLUTION: This bearing unit 1 comprises a sleeve 8 that is assembled with a shaft 2 and a plurality of bearings 4, 6 and has an integrally formed step part 8a for holding the respective bearings with a predetermined interval. Elliptic cylindrical surfaces 8b, 8c that are engaged with the respective bearing outside diameter surfaces and have an identical phase with each other are formed on inner surface of the sleeve 8.
