PURPOSE: To perfectly prevent the leakage of a hot pressure medium by opposedly arranging mutually engaged rotation stopping structures between a guide cylinder and an attaching hub having a guide cylinder and the lower end holding member of an elastic molded body attached thereto and a hot pressure medium passage and between the guide cylinder and a tube.
CONSTITUTION: In attaching a lower clamp ring 13 to a lower clamp ring hub 12 by a screw through a screw inlay part 17, the damage in each packings 18, 24 of hot pressure medium supply and discharge pipes 20, 26 and the parts of rotary joints 30, 31 of the pipes 20, 26 formed by receiving the resistance during screw attachment is perfectly prevented by providing rotation stopping structures 35, 36 due to fitted gaskets 32, 33. By eliminating the leakage of the hot pressure medium generated by said damage, troubles due to the leakage of the hot pressure medium such as hot steam, hot water or a hot gas are eliminated to obtain the safety of work and preservation of the environment. The predetermined inner pressure of the hot pressure medium is accurately maintained to enhance vulcanization molding effect.
