Abstract
A rotary cooling roller includes outer and inner cylinders, two end plates fixed to both ends of the outer cylinder, and a supporting shaft protruding from the end plates. A cylindrical space, provided between the outer and the inner cylinders, communicates with the inner space of the inner cylinder via through-holes formed in the inner cylinder. A coolant contained is allowed to flow back and forth between the cylindrical space and the inner space of the inner cylinder. Ring-shaped spacers are provided in the cylindrical space for passing an external force exerted on the outer cylinder to the inner cylinder.
