ABSTRACT:
A massage device having kneading balls includes a vibrating device provided between each of the kneading balls and a connecting member for vibrating the ball. The connecting member is a spring, such as a coiled spring, which is elastically deformable in a direction perpendicular to its axis. The connecting member is attached to a rotary plate rotatable inside a housing, eccentrically with respect to the rotary plate and rotatable relative thereto. The housing is further provided therein with a rotation control device for preventing the connecting member from rotating about its own axis with the rotation of the rotary plate. This prevents the vibrating device on the connecting member and the kneading ball from rotating with the rotation of the rotary plate.
