Abstract

An electric shaver with a drive shaft having a first rotary axis and a drive pin connected to the drive shaft eccentrically with respect to the rotary axis, and a driven shaft having a second rotary axis. The driven shaft is indirectly coupled to the drive shaft by a gear mechanism capable of converting a rotary motion of the drive shaft into a reciprocating motion of the driven shaft.
