Is transmitted to the fixed side transformer, and is transmitted to the outside from the fixed side transformer. Then, with the plate attached to the fixed side transformer by inserting a slight gap at one side shaft end of the fixed shaft, the parallel part of the inner peripheral part of the plate is fixed to the flat part of the one side shaft end of the fixed shaft. Since it is arranged in parallel with the fixed side transformer to prevent it from rotating, it is possible to obtain a roll device with outstanding maintainability and reliability, and it is sufficient to attach a plate to the end surface of the fixed side transformer. In addition, when the rotation of the roller is stopped, the rotation of the fixed side transformer can be prevented by contact without contact and only during rotation of the roller.
It is not necessary to perform various processing on the fixed-side transformer or the one-side shaft end of the fixed shaft, and a roll device excellent in workability, workability, and economy can be obtained.
