Patent ID: 7171751

Claim:
An electric shaver comprising a cutter head pivotally provided on an upper portion of a shaver main body so as to pivot in a forward-rearward direction on said shaver main body and which is provided therein with a plurality of cutter units, each of said cutter units having an outer cutter and an inner cutter that reciprocates while making sliding contact with an inside surface of said outer cutter and means operable by a user for manually and selectively pivoting said cutter bead in said forward-rearward direction to a plurality of predetermined angles of inclination, wherein said shaver is provided with a plurality of oscillating members that convert a rotational driving, which is supplied from a driving source inside said shaver main body via a plurality of motor joint portions connected in a plurality of locations in a direction of a height of said shaver main body by a plurality of eccentric pins, into a reciprocating driving oriented in mutually opposite directions and transmit said reciprocating driving oriented in mutually opposite directions to said cutter units; and wherein said plurality of oscillating members are connected to said plurality of eccentric pins which are installed upright at positions whose phases are substantially opposite and said plurality of eccentric pins are provided above and below at least one of said plurality of motor joint portions; whereby the distance over which a driving force from the driving source is transmitted to a plurality of cutter units in a cutter head that is pivotally disposed on the shaver main body is minimized so as to improve driving efficiency and reduce cutter head size.
