    摘要： A manufacturing method for a worm wheel, the worm wheel meshed with an operational worm at usage, has steps of preparing a worm wheel, in which at least a surface layer of a tooth portion is made of synthetic resin, preparing a machining worm, in which pitch of teeth of the machining worm in an axial direction thereof is the same as that of an operational worm, diameters of tip and root portions of the tooth of the machining worm are equal to or more than those of the operational worm and abrasive grains are provided on a surface of the machining worm by means of electro-deposition, disposing the machining worm in a twisting position relative to the worm wheel and rotating the machining worm and the worm wheel with meshing each other so as to machining the tooth portion of the worm wheel.
