To provide a bearing structure which does not cause slid, dust, breakage and deformation or the like in a wide operating temperature range from a room temperature to a high temperature.
The bearing structure has a shaft 120 and a plurality of bearings 150A-150G, and the shaft 120 has a bending elasticity and is bent into an arch-like shape within a range of elastic deformation. The plurality of bearings 150A-150G, which are arranged in an arch-like structure to be along the shaft 120 bent into an arch-like shape, support the shaft 120, and a clearance C is set between the shaft 120 and the inner ring of each of the bearings 150A-150G, and the shaft 120 is supported by the plurality of bearings 150A-150G through an O-ring 170 placed in the clearance C.
