Abstract
PURPOSE: To improve vibration-proof effect as well as prevent deformation and wear of rotary blade connecting parts by providing each convex portion and concave portion of a rotary blade with a projection along the rotating direction, respectively, and by inserting the connector having specific shape into the end of adjacent projections so as to be able to slide freely.
CONSTITUTION: The convex portion 4A and the concave portion 4B of a rotary blade are provided, as a body, with No.1 and No.2 projections 15 and 14, respectively, each of which is provided with the hole 17 having a same cross-section. Connectors 16 and 23 are inserted into each hole 17 so as to be able to slide freely. The hole 17 is, then, formed from an upstream semmicircular part 19 of a small diameter and a downstream semicircular part 20 of large diameter and the jaw parts connecting these semicircular parts with curves, and the holes 17 of each projection 14 and 15 are formed in opposite direction to each other. The connectors 16 and 23 have the approximately same cross-section as the hole 17. The central ends of the connectors 16 and 23 are formed into a tapered surface 29, projected gently and convexly, and a tapered surface 29, flat shaped, respectively, and the above-mentioned projections 14 and 15 are connected through the fitting between these tapered surfaces 29 and 28.
