ABSTRACT:
An electric shaver comprises a housing (1) formed as a grip, a shaving head (2) comprising at least one cutting unit (11) having an outer cutting member (16) and an inner cutting member which is rotatable relative to the outer cutting member, and drive element for driving the inner cutting member, the shaving head being pivotably connected to the housing. In known shavers the motor is accommodated in the shaving head, resulting in a poor balance and poor contact between the shaving head and the skin. According to the invention the shaver is characterized in that a motor (5) belonging to the drive element is accommodated inside the housing (1), the drive element being adapted to follow the pivotal movements of the shaving head (2) relative to the housing. Preferably, the drive element comprises flexible coupling element, for example a pulley-belt transmission (9, 12, 15) but alternatively the drive element may comprise a universal joint.
