受。[Claims for Utility Model Registration] A hydrodynamic bearing consisting of a bearing member and a shaft body, in which a cylindrical hole provided in the bearing member is located at a thrust bearing surface and at two locations spaced apart in the axial direction. The shaft body has a cylindrical radial bearing surface, and the shaft body disposed in the cylindrical hole has a thrust surface facing the thrust bearing surface, and a thrust surface facing each of the radial bearing surfaces.
and a herringbone-shaped groove is provided in at least one of the radial bearing surface and the radial surface, and the herringbone-shaped groove on one side in the axial direction is arranged in the axial direction. In a hydrodynamic bearing whose axial width dimension is shorter than the herringbone groove on the other side, the groove angle of the herringbone groove on the one side is the same as that of the herringbone groove on the other side. A hydrodynamic bearing characterized by having a groove angle smaller than the groove angle.
