摘要:
A weight for a vibration motor, the weight including: a resin part including: a semi-cylindrical portion having a shaft hole in which a rotary shaft is fitted and expanding radially from the shaft hole at a given center angle so as to be eccentrically weighted with respect to the shaft hole; and a pair of locking projections respectively disposed at both axial end areas of an outer circumferential surface of the semi-cylindrical portion so as to extend radially outwardly therefrom; and a metal part attached to the resin part so as to sit on the outer circumferential surface of the semi-cylindrical portion, the metal part including: a pair of locking recesses positioned and configured to correspond respectively to the locking projections of the resin portion, wherein an elevated portion formed between the pair of locking recesses makes contact with the pair of locking projections of the resin portion.
