Driving device of massaging chair
 A driving device of the massaging chair including a main shaft, a bevel gear mounted on one end of the main shaft, a worm rod mounted on another end of the main shaft, and a driving rotor mounted slidably between the bevel and the worm rod. When the main shaft is driven by a motor to turn forward, the driving rotor is engaged with the bevel gear to actuate a kneading shaft of the massaging chair. When the main shaft is driven by the motor to turn backward, the driving rotor becomes disengaged with the bevel gear and moves away from the bevel gear to engage the worm rod so as to actuate a beating shaft of the massaging chair.
