摘要： Workpieces are disposed between a pair of side walls in a heat treatment chamber. A centrifugal fan is disposed to face the workpieces inside the heat treatment chamber, and sucks gas from the workpiece side and generates air current. In regions at the respective side wall sides relative to an intermediate position between the pair of side walls, an air current regulation unit regulates the air current so as to restrict flows of the air current from the centrifugal fan to the respective side wall sides when a rotary blade of the centrifugal fan rotates in regions in which outer circumferential edge portions of the rotating rotary blade separate from the respective side walls, and allows the flows in regions in which the outer circumferential edge portions of the rotating rotary blade approach the respective side walls.

摘要： A shaft of a stirring fan for a heat treatment apparatus includes a blade fixing portion for fixing a plurality of blades. The blade fixing portion has a cylindrical portion extending in a shaft direction of the shaft. A hole inside the cylindrical portion is open to one end face of the shaft. The stirring fan has a discharge portion for discharging gas inside the cylindrical portion to the outside of the blade fixing portion. The discharge portion is open to the outside of the blade fixing portion, at a position away from the one end face of the shaft.
