受。[Claims for Utility Model Registration] A shaft is housed in a sleeve in a housing, and a groove provided on at least one of the inner peripheral surface of the sleeve or the outer peripheral surface of the shaft generates dynamic pressure to support the shaft in the radial direction, In a hydrodynamic bearing configured to support the shaft in the thrust direction by providing a thrust bearing in the housing so as to be located below the shaft, the thrust bearing is attached to the outer periphery of the thrust bearing in the housing. There is communication between the inside and outside of the thrust receiver until it is fitted into the specified position of the housing, but when the thrust bearing is fitted into the specified position of the housing, it is covered by the housing and there is communication between the inside and outside of the thrust bearing. A hydrodynamic bearing characterized by having grooves that do not communicate.
