摘要： Electric shaver of battery powered and washable type having a watertight housing structure. A battery covering detachably mounted to housing bottom opening for holding batteries inside the housing includes a lock and seal which are activated, responsive to the covering's mounting operation, respectively in directions transversing the housing axis to lock the covering to the housing interior wall and in the housing axial directions to achieve uniform abuttment of the covering to the interior wall for clamping therebetween a watertight ring seal. At the housing head where shaving blade assembly is coupled to rotary shaft of electric motor, the shaft is projected out of an axial cylinder of motor mounting member through a double-lip shape bushing watertightly sealing around the shaft with both axial end and outer peripheral projections compressively deformed by inward flange and inner periphery of the axial cylinder and motor shaft bearing so as to maintain a proper sealing pressure about the shaft, while allowing water passed through cut-hair reservoir between the motor and the blade assembly with side wall apertures of the reservoir closable by a shutter ring slidably fitted therearound, and in a housing side wall a reed-switch inside the housing is controlled over the side wall by a magnet carried by a handle slidably fitted outside the wall.
