いない。2. Description of the Related Art Curved arc toothed gears having a circular arc trace are known, but curved toothed gears other than arcs are not known. Since the teeth of this arcuate tooth resilient gear have high bending strength and do not generate thrust in the axial direction, they have the advantage that they can be supported by a bearing having a simple structure. However, conventionally, when cutting an arc-shaped toothed gear, a Gleason-type ring-shaped cutter has been used to create one tooth at a time. This method has low working efficiency and it is difficult to perform gear cutting by this method using a general-purpose machine, so that this kind of gear has not been put to practical use.
