Abstract
There is provided a resin fan capable of enhancing the mechanical strength in a weld part in view of the direction of reinforcing fiber. On the outer peripheral surfaceof a cylindrical rib, convex partsare formed in the middle portions between the portions in which radial ribsadjoining each other are connected to the cylindrical rib. The cylindrical ribis formed so that the thickness T in the radial direction thereof is decreased gradually from the base partthereof toward the tip end part. Further, the height Hof the cylindrical ribis set so as to be larger than the height Hof the radial rib. Thereby, at the time of molding, the resin flows in the portions of the cylindrical riband the convex partsare complicated, and thereby the orientation of glass fiber mixed in the resin is complicated.
