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. L'invention porte sur un cylindre support qui porte un ruban de verre en forme de bande et qui comprend : un élément rotatif qui vient en contact avec le ruban de verre ; un élément arbre dont l'intérieur comprend une voie de passage de fluide frigorigène et qui tourne conjointement avec l'élément rotatif ; et un élément faisant saillie qui fait saillie de la périphérie externe de l'élément arbre et qui comprend une voie de dérivation qui part du trajet de circulation de fluide frigorigène. L'élément rotatif est formé à partir de céramique. Un élément de transfert de chaleur qui a une conductivité thermique plus élevée que l'élément rotatif est disposé entre l'élément faisant saillie et l'élément rotatif.
