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.
