Abstract
A hydrodynamic bearing assembly includes a sleeve rotatably supporting a shaft, a thrust plate housing portion extending to an upper side of the sleeve in an axial direction so as to house a thrust plate, and a stopper ring housing portion stepped in an upper side of the thrust plate housing portion in the axial direction and housing a stopper ring for fixing the thrust plate. The stopper ring protrudes from the stopper ring housing portion such that an outer circumferential surface of the stopper ring has a larger height than an inner circumferential surface of the stopper ring housing portion.
