Abstract
PURPOSE: To prevent formation of a weld due to injection molding by forming a circular ring piece only around the periphery of a front edge of each blade of an axial fan.
CONSTITUTION: Spaces S, S' are provided between each ring piece by setting an anti-tip vortex piece (ring piece) 3a, 3b and 3c only on each blade 2, 2', 2"... Therefore, a weld phonomenon, occurring from an impact of the flow of resin material when resin is injection molded, will not be generated.
