）が邪魔になるためこの方法による加工が困難である。One of the methods for manufacturing gears is U.S. Patent Nos. 3 and 9.
As described in the specification of No. 10,091, it is known that there is a plastic working method in which gears are manufactured by forcing a plurality of gear materials into a die having tooth profiles with a punch and sequentially extruding them one by one. . According to this method, the gear can be manufactured easily and efficiently, and the labor and man-hours can be greatly reduced. For gears with gears, the boss (7
) are in the way, making it difficult to process using this method.
そこで、従来は組合せ歯車（４）を構成するこれら個々

製造方法である。In order to solve the above problems, the present invention provides a combination gear (6
i (at least one gear of 81' (for example (8)
) can be manufactured using the above-mentioned efficient manufacturing method by making the boss part of the gear with an aperture and a relatively large central shaft hole, and the other gear (for example, (6)) can be manufactured using the conventional die forging method. , the gears formed in this way are integrally joined together. That is, the feature of the method of the present invention is that a hollow material having flat both side surfaces and a relatively large diameter center shaft hole is pressed by a punch and passes through an internal tooth-shaped tooth forming part formed in a die. A first gear is manufactured by forming external teeth corresponding to the tooth forming part, and a boss part that can be fitted into a relatively large diameter center shaft hole of the first gear is manufactured. manufacturing a second gear having a second gear having the boss portion fitted into the relatively large diameter central shaft hole;
This is a method for manufacturing a combination gear in which the gear and the second gear are integrally connected.
