ABSTRACT:
A forming method of a tooth trace of a gear according to the present invention includes: a first step of preparing a preformed gear made of metal including a cylindrical main body and a tooth part having a flat tooth flank having a uniform thickness in a tooth trace direction inside of the main body; and a second step of conducting a surface treatment locally to an outside surface of the main body in order to deform the outside surface of the main body in such a manner that the same becomes concave, so that a crowning bulging in the tooth trace direction is formed on the tooth flank of the tooth part.
