PROBLEM TO BE SOLVED: To improve cooling function, without increasing the distorting deformation when a rotary type pressing roller is pressed to a rotary type cooling roller which is composed of a cylindrical body 11, and a support shaft 12 projecting outward from the center of lid plates 13 and 14; and formed by providing a cooling pipe 17 in when a cooling water flows, as well as filling an operating fluid to repeat the evaporation and the condensation. SOLUTION: An inner tube body 18 to surround the cooling pipe 17 is provided to form a clearance 19 in the circular form between the inner tube body 18 and the cylindrical body 11, inside the cylindrical body 11. While numerous pass holes 20, through which the operating fluid can run forward snd rearward freely in the above clearance and the concerned inner tube body are formed in the inner tube body 18, spacers 22 are provided in the above clearance 19, and the pressing force to the inner tube body is supported by both the concerned cylindrical body and the inner tube body 18. |
