Abstract
A bearing component for rotatably receiving a rotating shaft on an end of a rotating unit includes a component body, an inner protrusion, and one or more outer protrusions. The component body has a recess into which the rotating shaft is rotatably inserted. The inner protrusion protrudes from a wall portion of the recess facing an end surface of the rotating shaft. The inner protrusion receives an axial load by the rotating shaft. The outer protrusions protrude from an outer surface of the component body opposite to the recess. The one or more outer protrusions are in contact with a holding unit. A contact portion between the outer protrusions and the holding unit is offset from a contact portion position between the inner protrusion and the end surface. The contact portion between at least one of the outer protrusions and the holding unit has a non-planar shape.
