Abstract
A gearmade of a resin includes webs(and) formed so that the rigidity of the web is increased by a first circumferential rib, a second circumferential rib, first diametrical ribsand second diametrical ribs, and the circumferential sectional shape of the outermost webis a corrugated shape, whereby the rigidity of the outermost webis increased. As a result, it is possible to increase the rigidity of the outermost webwithout increasing of the thickness of the outermost web; to form a toothed portionwith a high accuracy; to reduce the deformation (for example, the amount of displacement of the toothed portionand a shaft-supporting portionin a rotating direction) due to an external force; and to enhance the rotation-transmitting accuracy. In this gear, a vibration and a noise due to the vibration can be reduced by increasing the rigidity of the web.
