ABSTRACT:
A vibratory dry-shaving apparatus comprises a housing; a bipolar, uniphase, synchronous motor positioned within the housing and having a rotor and a stator; and a shaving head arranged on the housing and including a vibratory cutter part below a fixed cutter part. A wall separates the interior of the housing from the shaving head, such wall having a passage therethrough. A swing lever is driven by the rotor and engages the vibratory cutter part to drive the latter, the swing lever extending through the passage. An elastic sleeve surrounds the swing lever and seals the passage between the edge thereof and the swing lever. The elastic sleeve is asymmetrically designed so that, in a final end position of the vibratory cutter part where the magnetic fields of the rotor and the stator are parallel, no force resulting from deformation of the sleeve is exerted on the vibratory cutter part.
