Abstract
According to the invention, when a plurality of radial ribs are formed integrally with the web of a spur gear for the sake of rigidity thereof, the same rigidity as that of heretofore known gears can be assured while increasing the size accuracy of gear in comparison with the usual gears by locating the ribs with outer ends thereof opposed to the base of corresponding teeth.
