BEARING STRUCTURE

This bearing structure (1) is characterized by comprising: a rolling bearing (2); a substrate (3) that has the rolling bearing (2) attached thereto and has an engaging section (32a); a first fixing member (4) having a first restricting section (41) that restricts movement of the rolling bearing (2) toward one side in the X-axis direction, and being immovable relative to the substrate (3) in the X-axis direction; and a second fixing member (5) having a second restricting section (51) that restricts movement of the rolling bearing (2) toward the other side in the X-axis direction, an engaged section (52a) that engages with the engaging section (32a), and a support section (52b) that supports the rolling bearing (2) in the radial direction. As such, the bearing structure (1) can restrict movement of the rolling bearing (2) toward both sides in the axial direction, and eliminate play in the radial direction of the rolling bearing (2).
