JPS5476358A - Reciprocating type electric razor operating device - Google Patents

Abstract

PURPOSE: To provide the subject device wherein a balancer which makes a swinging motion in a direction perpendicular to the sliding direction of the inner blade base is inserted through a core rod of an eccentiric cam, thereby to receive the load by the elastic legs of the balancer to suppress the vibration.

CONSTITUTION: When a motor 2 is rotated, an eccentric cam 4 axially supported by the motor 2 is rotated, and a frame piece 5b makes a reciprocating motion in a direction shown by arrow by the operation of a core rod 4a projected upwardly. While the operating member 5c at the lower part of the frame piece 5b vibrates in a direction perpendicular to the direction shown by arrow, the vibration is absorbed the elasticity of the operating member 5c itself. However, since there is the wear of the inner blade base 6 with respect to the vibration in the direction shown by arrow, the vibration receives the load as a suppressive force. Then, in accordance with the rotation of the core rod 4a of the eccentric cam 4, the elastic plate 10a of the balancer 10 inserted through the core rod 4a is bent and deformed. The deformation of the elastic plate 10a offsets the vibration in the rectangular direction of the inner blade in correspondence to the sliding movement of the inner blade base 6, and therefore the vibrate on of the razor can be reduced.
