In the bearing unit, a radial bearing clearance and thrust bearing clearances are set at such widths that a tilted spindle member comes into contact at the outer periphery of its spindle with both axial ends of a radial bearing surface opposed thereto, as well as at the rims of both end faces of its flange portion with respective thrust bearing surfaces opposed thereto, so that the moment load can by supported by both the radial bearing part and the thrust bearing part. Specifically, the radial bearing clearance &dgr;R and the thrust bearing clearances &dgr;A are set in accordance with the expression D&dgr;R/L+&egr;≧&dgr;A≧D&dgr;R/L (where D is the diameter of the flange portion, L is the axial length of the radial bearing part, and &egr; is a machining error).
