The invention relates to a reciprocating driving device for a movable member such as a movable hair shearing blade assembly in reciprocal type electrical shaver. A reciprocally driven mounting member is coupled to an eccentric shaft of a motor and comprises a carrier which carries the movable blade. Resilient legs support the plate part for movement only in the direction of reciprocation and are fixed at the other end. Each leg includes at least two parts joined intermediate their ends by a rigid member disposed parallel to the carrier. A driven arm extends from the carrier to flex only in directions perpendicular to the direction of reciprocation. |
