摘要: A gear subassembly is for an exhaust gas recirculation (EGR) system including an EGR valve and a rotatable shaft provided for the EGR valve. The gear subassembly includes a gear and a cam. The gear is a part of reduction gears and is fastened to the rotatable shaft to rotate therearound. The cam is fastened to the gear and is a part of a link mechanism. The gear includes a metal shaft-fastening part used for fastening the gear to the rotatable shaft, and a metal cam-fastening part used for fastening the gear to the cam. The gear is formed by resin-molding with the shaft-fastening part and the cam-fastening part serving as insert parts.
