Abstract
In a roller support device, an inner peripheral surface of a bearing box is covered with a material having a poor wettability with respect to a molten metal, such as tantalum, graphite, C/C composite, silicon carbide or the like. The molten metal does not adhere to the covered portion, or even if the molten metal adheres to and is solidified on the covered portion, the molten metal can be peeled off with a light force. Therefore, after a support roller is pulled up from the molten metal, the molten metal does not prevent a rolling bearing from shifting in the axial direction thereof so that the roller support device can prevent an excessive force from being applied to the rolling bearing when the support roller, after it is thermally expanded once, is contracted as the temperature falls.
