PURPOSE:To stabilize quality of a moving plastic vane, to improve strength, and to reduce a cost. CONSTITUTION:A moving plastic vane is structured such that auxiliary vanes 6 serving as a blast guide vane having approximately the same thickness as that of the main vane 5 are arranged at intervals of a given distance. Two ends of a portion between the main vane 5 and the auxiliary vane 6 are interconnected through side plate 9, and the intermediate part thereof is intercommunicated through a plurality of ribs 10. In this structure, the progress of cooling after formation of the main vane is the same as that of the guide vane, no curve due to a difference in a cooling time is produced, quality is stabilized, a cost is reduced, and besides a proof stress against an external force is increased by means of the ribs. |
