ABSTRACT:
Electric shaver of reciprocal vibration type having improved vibration member for converting rotary motion of motor into reciprocal vibrating motion of inner cutter is provided. The member comprises an integral body of a driving plate part to be coupled on one side to the inner cutter, leg parts respectively extended from each end in directions of the reciprocal vibrating motion of the plate part and flexible only in said directions, a mounting base part coupled to extended ends of the leg parts for mounting the member to stationary part in shaver housing, and an arm-shaped connecting part extended from the other side of the plate part for directly connecting it to eccentric cam of the motor at free end of the connecting part and having a flexibility in directions perpendicular to the reciprocal vibrating directions of the plate part. Components of the rotary motion of the eccentric cam directly transmitted to the connecting part of the vibration member in said perpendicular directions are absorbed by the flexibility of the connecting part, whereby the driving plate part is vibrated only in the reciprocal vibrating directions as supported by the leg parts being flexible only in such directions.
