Abstract

Provided are a fluid dynamic bearing, a motor, and an optical deflector, for which a fixed shaft can be attached with little axial eccentricity. The bearing () is equipped with a fixed shaft (), a sleeve () provided so as to be capable of rotating around the fixed shaft (), dynamic pressure generating sections () provided in the sleeve (), and a lower case () for securing the lower end () of the fixed shaft (). In addition, the bearing is equipped with a retaining case (), which has a chuck () that retains the upper end () of the fixed shaft () secured by the lower case (), and which can be secured to the lower case () in a state that does not generate pressure causing the axial center of the fixed shaft () to move.
