摘要： PROBLEM TO BE SOLVED: To reduce thermal stress and realize cost reduction by forming a tire disk in a ring cut by a slit which extends from an inner peripheral surface of the tire disk to an outer peripheral surface thereof and which opens slantwise with respect to the axis of a core bar in the outer periphery of the tire disk. SOLUTION: A slit type tire roller is used in an atmosphere of high temperature such as a soaking pit and is made by mounting a plurality of tire disks 13 on a core bar of internal water cooling type and by covering the outer periphery of the core bar by thermal insulator. Since the tire disk 13 has a slit 17, it is freely expanded in a peripheral direction in a usage state of high temperature atmosphere to absorb the thermal expansion by the slit 17, which can almost prevent the generation of thermal stress. The outer peripheral surface 13a of the tire disk 13 always abuts on a carried body at a part existing in the direction of thickness via the slit 17 and can ensure the continuity of the outer peripheral surface 13a of the tire disk 13 to smoothly carry the carried body.
