PROBLEM TO BE SOLVED: To simplify and miniaturize a constitution, and to simplify an assembling process, while preventing leakage of a viscous fluid such as lubricating oil. SOLUTION: This bearing unit has a radial bearing 33 performing the support in the peripheral direction of a shaft 31, a first housing 34 arranged on the outer peripheral side of the radial bearing and one end side in the axial direction and holding the radial bearing, and a second housing member 35 arranged on the outer peripheral side of the first housing member 34 and the other end side in the axial direction of the radial bearing. The first and second housing members 34 and 35 are integrated by a screw part 34a arranged on the outer peripheral side of the fist housing member and a screw part 35a arranged on the inner peripheral side of the second housing member, and have a shaft insertion hole 41 for sealing and storing the radial bearing 33 and inserting the shaft 31 into one end side or the other one side in the axial direction. The viscous fluid 42 is filled in the integrated first and second housing members 34 and 35. COPYRIGHT: (C)2007,JPO&INPIT
