ABSTRACT:
It is an object of the present invention to provide a miniaturized, high-precision, easy, and low-cost dynamic pressure bearing device and a manufacturing method thereof. In manufacturing a dynamic pressure bearing device, a first and a second ring-shaped member are fixedly fitted to an outer peripheral surface of a rotating shaft member to constitute a rotating portion, an intermediate member is disposed between these members to constitute a fixed portion, a thrust bearing portion is formed in gaps between the first and second ring-shaped members and the intermediate member, and a journal bearing portion is formed in a gap between the rotating shaft member of the rotating portion and the intermediate member, the first and second ring-shaped members being fixed only with an adhesive applied on surfaces thereof which is to be fitted to the rotating shaft member.
