Therefore, even if the fixed covering portion 162 is selectively provided in approximately the center of the plate main body portion 152 in the X direction, the portion of the plate main body portion 152 that is not covered by the heat-resistant sheet 160 can be made less susceptible to the effects of the gas G.

  • the opening direction of each movable covering portion 164 can be controlled depending on the position of the slit 164a around each movable covering portion 164 in the Z direction.
