Abstract
A cooling fan made of synthetic resin for an air-cooled engine which is fixedly secured to a side of the body of a flywheel includes a plurality of cooling fins formed along a circumferential direction thereof, and a circular reinforcement rib projecting axially from the periphery of a backboard, thereby reducing deformation of the fan during running of the engine and preventing deformation of the fan during transportation, without significantly increasing the weight of the fan.
