Inner blade member for electric dry shaver

摘要

Electric dry shaver with reciprocally driven inner blade assembly high in uniform contact pressure distribution against outer blade foil accompanying less frictional heat. The inner blade assembly having parallelly spaced arcuate blades on an elongated semicylindrical frame is coupled substantially at both longitudinal ends of the frame to a connector likewise elongated which transmits to the assembly at the both ends a force urging it to the foil and reciprocal vibrating motion for shaving while the force and motion are given to the connector at its center, preventing arcuate bending of the inner blade assembly.
