The invention provides a bearing device for a rotating shaft. Shape deformations during manufacturing (molding) and using are inhabited at a minimized extent, fully stability and reliability as a bearing are ensured, cost reduction of parts and cost reduction manufacturing are achieved, mechanical strength is ensured, and effects of lightweight, manufacturing ease improvement and material cost reduction are obtained. A bearing part is disposed on a housing and supports the rotating shaft to be capable of rotating freely. When the bearing device provided with the bearing part is formed, the bearing part is integrally formed by utilizing a synthetic resin material and the housing in such a manner that the bearing part forms in the shape of a ring which has a specific thickness in the axial direction and a specific annular thickness in the radial direction, and a plurality of tolerance absorption recessed parts are formed in an end face of the bearing part; and the multiple tolerance absorption recessed parts are configured in such a manner that the tolerance absorption recessed parts are spaced at specific intervals in the circumferential direction, and the bottom is selected as a specific thickness, so the distance between the tolerance absorption recessed parts and the inner circumferential face of the bearing part is selected as the specific thickness.
