ABSTRACT:
The electric shaver is provided with outer blades, inner blades driven in reciprocating motion against the inner face of the outer blades and a driving mechanism driving the inner blades in reciprocating motion. The driving mechanism is provided with vibrating rods, which transmit the reciprocating motion and are connected at their extremities to the inner blades. Vibrators are connected to the vibrating rods and are mounted in a case. A reciprocating motion mechanism drives the vibrators in a reciprocating motion. The vibrating rods are connected to drive ports of the inner blades in a fashion allowing movement in an axial direction. Furthermore, blade-pushing springs, which permit the flexible reciprocating motion of the inner blades against the outer blades, are introduced on the vibrating rods such that the inner blades are pressed against the outer blades by the blade-pushing springs.
