2. Description of the Related Art When a gear preform is set in a forging die as described above, the tooth profile of the preform must be positioned so as to match the shaping teeth in the forging die. Conventionally, in a gear having a tooth profile with a chamfer for guiding, such as a reverse idle gear or a clutch gear, positioning is performed while checking the fit state of the chamfer portion of the preform and the shaping tooth with the feel of the hand. However, positioning was not easy with a gear without a chamfer.

The fitting of the chamfer portion and the tooth-shaping tooth has only a slight difference in height between the chamfer portion, and therefore skill is required to accurately and quickly match them. Moreover, not only is it inefficient to rely on manual work, but it is particularly dangerous in forging dies, and there has been a demand for immediate automation.
