摘要

Provided is a support roller that supports a strip-shaped glass ribbon and that comprises: a rotating member that comes into contact with the glass ribbon; a shaft member that has a refrigerant flow path in the interior thereof and that rotates together with the rotating member; and a protruding member that protrudes from the outer periphery of the shaft member and that comprises a branch path that branches from the refrigerant flow path. The rotating member is formed from ceramic. A heat transfer member that has higher thermal conductivity than the rotating member is arranged between the protruding member and the rotating member.
