Abstract
Provided are a conveying jig, a method of manufacturing the conveying jig, and a method of heat-treating metal rings using the conveying jig. The conveying jig is provided with a base and ten holding shafts raised from the base. Ridges and grooves are alternatively provided in the side wall of each holding shaft. The metal rings are held in position by being engaged in the grooves in the holding shafts. The space enclosed within the holding shafts is communicated with the atmosphere, and this allows, when the metal rings held by the conveying jig are subjected to heat treatment in a heat treatment furnace, an atmospheric gas to circulate in the space enclosed within the holding shafts.
