(Prior Art) An input port of a radioactive waste incinerator or the like is provided with a sliding damper that opens the input port only when waste is input and seals the input port during combustion. In order to drive such a damper, conventional mechanisms have been used to open and close the damper (1) using an air cylinder (11) as shown in FIG. 2, or to open and close the damper (1) as shown in FIG.
Attach rack O9 to the rack and pinion 0 meshed with it.
3), a mechanism for opening and closing the damper (1) was used.
