PROBLEM TO BE SOLVED: To provide excellent lubricating performance and rotating performance by suppressing vibration of a shaft by increasing the rigidity of the shaft and securely holding a lubricating oil. SOLUTION: This bearing unit comprises the shaft 31, a first radial bearing 32 supporting the shaft 31 in the circumferential direction, a second radial bearing 33 disposed axially apart from the first radial bearing 32 and supporting the shaft 31 in the circumferential direction, a thrust bearing 34 supporting one end of the shaft 31 in a thrust direction, a spacer 35 disposed between the first radial bearing 32 and the second radial bearing 33, a housing 37 with the first radial bearing 32, second radial bearing 33, and thrust bearing 34 disposed therein and sealed except for a shaft insertion hole 45 inserting the shaft 31, and a viscous fluid 38 filled in the housing 37.
