Abstract
PURPOSE:To facilitate assembly by providing an allowance onto a reinforcing member made of the material harder than a vane wheel for a shaft and by inserting said reinforcing member, suppressing rotation, and by joining the vane wheel and the reinforcing member. CONSTITUTION:A shaft insertion hole 17 for the insertion of a motor shaft 2 is formed on a reinforcing metal fitting 16 having an opened port for the fitting with positioning projections 12-15. The shape of the shaft insertion hole 17 is formed by cutting a circle by two parallel lines, and the interval between two lines is set equal to the thickness of the part where a flat surface part is formed in the vicinity of the top edge of the motor shaft 2. Therefore, even if the center of a vane wheel and the center of the reinforcing metal fitting deflect a little from each other, assembly is permitted.
