Abstract

See full text

The invention provides an improved vibrating device or electromassager including a vibrating plate rocking corresponding to rotation of a crank shaft interlocking with a motor, and a counter weight for compensating for reaction against rocking of the vibrating plate. In the vibrating device thus constructed, the center of gravity of the vibrating plate and that of the counter weight are disposed on the same plane perpendicular to the crank shaft. Accordingly no foce is applied to shake the vibrating plate in the direction of the crank shaft. The vibrating plate is thus rocked stably and noiselessly without making the body of the vibrating device bounce.
