The control circular is disposed in the outer casing. The outer casing has a massage surface and an installation trough. The power mechanism, the transmission mechanism, the big rotary disc and the small rotary disc are disposed in the installation trough. The power mechanism is electrically connected to the control circuit via an electric wire and controlled by the control circuit to operate. The power mechanism brings the big rotary disc and the small rotary disc to spin, respectively, through the transmission mechanism. The small rotary disc has a central shaft secured on the big rotary disc. The small rotary disc is formed with a ball aperture. The massage ball is disposed in the ball aperture. The big lid and the small lid cover the big rotary disc and the small rotary disc. The big lid has a big hole corresponding in position to the small rotary disc. The small lid has a small hole corresponding in position to the massage ball. The small hole has a diameter smaller than that of the massage ball. The massage ball has a portion exposed out of the small hole.
