Abstract

A method for manufacturing a worm wheel including an inner wheel element including a side plate portion and a tubular eave portion, and an outer wheel element including a wheel tooth portion on an outer circumferential surface thereof, and coupled and fixed to the inner wheel element in a manner of covering a radially outer portion of the side plate portion and the eave portion, the method includes: molding the outer wheel element by disposing a mold around a radially outer portion of the inner wheel element, and feeding the molten synthetic resin from an annular or arc-shaped injection gate toward a pocket portion that is continuous over an entire circumference of a cavity present between an inner surface of the mold and a surface of the inner wheel element and that is present on a radially inner side of the eave portion.
