Abstract
In an induction heating roller apparatus of the present invention, Rolling bearings 10 and a sliding bearings 14 are provided between drive shafts 2 of a roller body 1 and a support rod 9. When a trouble occurs in the rolling bearings 10, a rotational torque is transmitted from the drive shafts 2 through the rolling bearings 10 to the support rod 9. The sliding bearings 14 operate during the transmission of the rotational torque to the support rod 9, and the rolling bearings 10 slips relative to the support rod 9. The slip prevents that the support rod 9 co-rotates with the drive shafts.
