Beschreibung
Zusammenfassung:	The present invention includes a furnace, a plurality of pallets, a pusher device, and a pusher-puller device. The furnace includes a carburizing zone in which carburizing processing is performed upon workpieces loaded upon trays during the conveyance of these trays along a direction of conveyance, and a plurality of regions which are arranged successively along the direction of conveyance at the upstream side of the carburizing zone. Along with a tray upon which workpieces are loaded being mounted upon each one of the plurality of pallets, these pallets are movable along a linear conveyance direction, with the number of pallets being the same as the number of regions. The pusher device pushes the trays along the direction of conveyance. And the pusher-puller device, along with pushing the plurality of pallets all together forward along the direction of conveyance, also pulls one of the plurality of pallets backward into each of the plurality of regions.
