Abstract: A rotary electric shaver includes an outer cutter which has an upper surface with annular shaving faces, in which many hair-entry apertures are formed, and an inner cutter having small blades, which rotate in sliding contact with the lower surface of the outer cutter from below the shaving faces. The outer cutter (10) has a plurality of concentric annular shaving faces (16, 18), which are integrally formed therewith. The density of the hair-entry apertures (65) is varied in the circumferential direction of the plurality of annular shaving faces (16, 18). The rotary electric shaver increases the shaving area of the outer cutter to improve shaving efficiency and also restrains excessively close shaving thereby to protect skin even when the contact pressure of an area near the center of the outer cutter against skin increases.

Abstract: A rotary electric shaver includes an outer cutter having an upper surface with annular shaving sections, formed with hair entry apertures, and an inner cutter having small blades, which rotate in sliding contact with the outer cutter from below the shaving sections. The outer cutter has a plurality of concentric annular shaving sections. The shaving section adjacent to an outer periphery is lower than the shaving section adjacent to a center. The shaving sections are formed on a plane horizontal to a central axis. This makes it possible to increase a shaving area, to precisely trace the curved surface of a concave portion of skin and to come in contact with the skin with a proper contact pressure, thus permitting smooth shaving of the concave portion. The shaver has a simple structure with a smaller number of components, featuring easier assembly and easier removal of hair bits.
