摘要： A steel gear includes a substantially cylindrical outer peripheral ring portion having a toothed shape formed on its outer peripheral surface; and a flange portion extended radially inward from an inner peripheral surface of the outer peripheral ring portion. The steel gear has a thermal history layer formed in the outer peripheral ring portion, and the depth of the thermal history layer in the direction inward from the tooth bottom of the toothed shape of the outer peripheral surface is greater in the first protruding portion and the second protruding portion than in the coupling portion with the flange portion, and is substantially the same between the first protruding portion and the second protruding portion. As a result, even if the “carburization/slow cooling/high-frequency quenching treatment” is used as a manufacturing method of the steel gear, the steel gear has high dimensional accuracy.

摘要： A drive plate includes a disk-shaped plate portion; and a tooth-shaped portion formed at an outer peripheral end of the plate portion. The plate portion and the tooth-shaped portion are integrally shaped from a single steel plate material. The plate portion and the tooth-shaped portion include a carburized layer provided over an entire surface layer of the plate portion and the tooth-shaped portion, the carburized layer having a carbon concentration higher than that of a center portion of the plate portion and the tooth-shaped portion in a thickness direction. The carburized layer of the plate portion is higher in hardness than the center portion of the plate portion in the thickness direction. The carburized layer of the tooth-shaped portion has been subjected to a quenching process, and is further higher in hardness than the carburized layer of the plate portion.

摘要： A reduced-pressure heat treatment jig is used for supporting a workpiece of iron when the workpiece is subjected to heat treatment in a reduced-pressure atmosphere in which pressure is reduced compared to atmospheric pressure. The jig is formed of an iron material and is formed with a film on at least a contact surface with the workpiece, the film being formed of a material which persists during the heat treatment. The film preferably includes a metal oxide having an evaporating temperature higher than the heat treatment temperature in the reduced-pressure atmosphere. The film preferably contains aluminum oxide.
