Abstract
A heat-insulating bearing structure employs three disks so that peripheral edges of the disks come into contact with a circumferential side face of a rotary shaft, to support the rotary shaft. A contact part between the rotary shaft and each disk is small, and therefore, heat conduction from the rotary shaft to each disk is small. Accordingly, the bearing structure surely supports the rotary shaft even if the rotary shaft is heated to a high temperature. Each disk is provided with fins so that, when rotated, the fins draw in surrounding air and blow out the air from the peripheral edge of the disk toward the contact part between the disk and the rotary shaft, thereby cooling the contact part and surely supporting the rotary shaft.
