In film forming roll described above, the outer tube is more supported by the side members of each arranged rigid structure at both shaft ends, between the opposite sides of the side members, becomes elastically deformable flexible structure ing. Moreover, the heat medium liquid is made to flow inside the outer cylinder for roll cooling and internal pressure adjustment. Therefore, how to connect the thin outer cylinder and the side member in a liquid-tight manner with high durability has been a problem.

  In contrast, there are the following conventional techniques.

(1) an outer cylinder and the side members or glued, brazed (welded) or to those integrated (e.g., Patent Document 1).

(2) A rubber-like elastic O-ring or wedge-shaped seal member is sandwiched between the outer cylinder and the side member, and the outer cylinder and the side portion are caused by frictional resistance generated by a repulsive force due to elastic deformation of the O-ring or the wedge-shaped seal member. A member connected in a liquid-tight manner (for example, Patent Document 1).

Further, since the outer cylinder is deformed, the strength of the liquid-tight connection between the outer cylinder and the side member is not stable and is difficult to manage.

  (4) cannot be disassembled and lacks maintainability. Problems arise due to variations in the quality of brazing and welding to the outer cylinder and side member of the metal seal member.

Is configured as a wide O-ring groove that is sufficiently wider than the wire diameter of the O-rings 61 and 62 (about 2 to 2.5 times the wire diameter). The free dimension state refers to a state where the O-rings 61 and 62 are not elastically deformed.

  Metal collar members 63 and 64 are disposed in the concave grooves 59 and 60 adjacent to the O-rings 61 and 62 in the lateral width direction. The collar members 63 and 64 are at least divided into two so as to be fitted into the concave grooves 59 and 60, and are outside the outer ring members 57B and 58B from the O-rings 61 and 62 (the concaves of the right outer ring member 58B). The groove 60 is disposed adjacent to the right side of the O-ring 62 and is movable in the axial direction (left-right direction) in the concave grooves 59 and 60. The outer diameters of the collar members 63 and 64 mounted in the concave grooves 59 and 60 are set to be equal to or smaller than the outer diameters of the outer annular members 57B and 58B.

The O-rings 61 and 62 are elastically deformed in a compressed state between the outer annular members 57B and 58B and the outer cylinder 50 in accordance with the screwing amounts of the screw members 67 and 68. The flange members 69 and 70 prevent the outer cylinder 50 from bulging and deforming due to the repulsive force due to the elastic deformation of the O-rings 61 and 62.

  As a result, the outer ring members 57B and 58B and the outer cylinder 50 are connected and connected in a liquid-tight manner so that they cannot be displaced relative to each other by the frictional resistance generated between them by the repulsive force due to the elastic deformation of the O-rings 61 and 62. . At the same time, the outer cylinder 50 and the flange members 69 and 70 are connected and connected so as not to be relatively displaced by the frictional resistance generated between them due to the repulsive force caused by the elastic deformation of the O-rings 61 and 62.

Thus, the O-rings 61 and 62 are elastically deformed in a state in which the outer cylinder 50 is restrained from being swollen and deformed by the flange members 69 and 70, so that the outer cylinder 50 and the outer ring members 57B and 58B The strength of the liquid-tight connection can be stabilized, and the amount of elastic deformation of the O-rings 61 and 62 can be increased to increase the pressure resistance. The elastic deformation amounts of the O-rings 61 and 62 can be freely set to arbitrary values by adjusting the screwing amounts of the screw members 67 and 68.

Is configured as a wide O-ring groove that is sufficiently wider than the wire diameter of the O-rings 73 and 74 (about 2 to 2.5 times the wire diameter). Here, the free dimension state means a state where the O-rings 73 and 74 are not elastically deformed.

Metal collar members 75 and 76 are disposed in the concave grooves 71 and 72 adjacent to the O-rings 73 and 74 in the lateral width direction. The collar members 75 and 76 are at least divided into two so as to be fitted into the concave grooves 71 and 72 , and are outside the inner annular members 57A and 58A from the O-rings 73 and 74 (the concaves of the right inner annular member 58A). The groove 72 is arranged adjacent to the right side of the O-ring 74 and is movable in the axial direction (left-right direction) in the concave grooves 71, 72. The outer diameters of the collar members 75 and 76 mounted in the concave grooves 71 and 72 are set to be equal to or smaller than the outer diameters of the inner annular members 57A and 58A.
