Abstract

A therapeutic massage unit having an enclosed casing for massage application to the body which presents a container forming cylindrical body wall and hemispherical end wall which is vibrated by a gyratory motor pocketed therein. The other end of the container part is closed by a cover part which presents a cylindrical rim which is attachably secured to the container part and a tapered nose extension to which facial or scalp massage attachments may be removably applied. The speed of motor rotation and character of the massage vibrations are controlled by adjustable elements accessibly mounted on the cover part and which manipulate solid state circuitry compactly mounted within the cover part. A cooling air propelling and circulation arrangement is incorporated in the unit whereby the motor control circuitry and motor parts subject to heating during operation are washed in a stream of cooling air and maintained in the desired temperature range.
