Abstract

Abstract An improved electric hand-held vibratory massager is disclosed in which the brush holders for the massage are made of plastic, and the connectors for supplying electricity to the brushes are integrally molded into the plastic brush holders. The input power line is connected to the base of the massager and the electrical leads from the brush holders to the base pass through the vibratory spring that supports the motor on the base and then down through the standard that supports the spring whereby the amount of strain that the lead wires to the brushes must withstand is substantially reduced.
