。[Claims for Utility Model Registration] A groove for generating dynamic pressure is provided in at least one of the opposing end surfaces of the sleeve and the thrust receiver, through which the same shaft passes, and the rotation of the sleeve relative to the thrust receiver generates a dynamic pressure generating groove. A hydrodynamic bearing device that supports a shaft in the thrust direction by generating dynamic pressure in a fluid between a sleeve side end face and an end face of the sleeve opposite to the sleeve end face, the bearing device supporting the shaft in the thrust direction. The shaft hole of the thrust receiver has an inner diameter larger than the outer diameter of the shaft so that the thrust receiver can tilt with respect to the shaft, supports the thrust receiver in the axial direction, and
A hydrodynamic bearing device comprising a pressing member that prevents rotation of the thrust receiver with respect to the shaft.
