The outer portion has a plurality of injection-molded sections formed on a side surface of the insert portion which surface is directed transversely or perpendicularly to the central longitudinal axis. To produce the gearwheel inexpensively and with sufficiently good physical properties as regards its load-bearing capacity and its useful life. The gearwheel is characterized in having injection-molded sections spaced apart from one another on the side surface of the insert portion and side surface areas of the insert portion are left free between directly adjacent injection-molded sections.
