| description | A gas carburizing apparatus (1) includes a carburizing container (2), a rotation support member (3), an induction heating coil (4), an inner injection nozzle (51A), and an outer injection nozzle (52). The carburizing container (2) houses a workpiece (7) having a cylindrical portion (71). The rotation support member (3) is for rotating the workpiece (7) around a center axis (O1) of the cylindrical portion (71). The induction heating coil (4) is for induction-heating the workpiece (7). The inner injection nozzle (51A) is arranged in the carburizing container (2), and injects an inner carburizing gas (G) to thereby cause the inner carburizing gas to collide with an inner circumferential surface (711) of the cylindrical portion (71). The outer injection nozzle (52) is arranged in the carburizing container (2), and injects an outer carburizing gas (G) to thereby cause the outer carburizing gas to collide with an outer circumferential surface (712) of the cylindrical portion (71). |
