Abstract

PURPOSE: To keep a junction less capable of breaking and also to obtain such moving blade as is light and high in screw strength by diffusing and junctioning a material higher in mechanical strength than the moving blade body to the screw of the moving blade body at a surface slanting to a moving blade shaft.
CONSTITUTION: A moving blade body 1 is provided with a screw outside its cylindrical part 1b, and a moving blade shaft 2 having a flange 2a and a turn-stop 2b is clamped and coupled to its end. Then, with a conical junction provided therefor, a junction member 1c of such material as is higher in mechanical strength than the moving blade body 1 is diffused and junctioned to the screw of the cylindrical part 1b. Thus the junction is increased in area and stress is unified to decrease apprehension of breaking, and a moving blade light and high in mechanical strength is obtainable.
