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; and a shaft member that has a refrigerant flow path in the interior thereof and that rotates together with the rotating member. The rotating member is formed from ceramic. A first thermal insulation member that has lower thermal conductivity than the rotating member is arranged between the inner periphery of the rotating member and the outer periphery of the shaft member that is inserted in a through hole in the rotating member. La présente invention concerne un cylindre support qui soutient un ruban de verre en forme de bandelette et qui comprend : un élément rotatif venant au contact du ruban de verre ; et un élément arbre dans lequel se trouve un circuit fluidique réfrigérant et tournant avec l'élément rotatif. L'élément rotatif est constitué de céramique. Un premier élément d'isolation thermique ayant une conductivité thermique inférieure à celle de l'élément rotatif est disposé entre la périphérie intérieure de l'élément rotatif et la périphérie extérieure de l'élément arbre, qui est inséré dans un orifice traversant de l'élément rotatif.
