PROBLEM TO BE SOLVED: To prevent a motor from being over-heated, to prevent fingers or the like from being caught and to improve safety by constituting a massage instrument to stop whole driving means in case an over-load is added to any one of driving means. SOLUTION: In case a load on plural geared motors, for example, the two motors M and M arranged in a treating body becomes the over-load, the over- current is respectively detected by over-current detecting circuits 7. The whole geared motors M are stopped based on the detection in configuration. A control part 8a and a timer 8b are arranged in a circuit. When a fixed time, for example, 15 minutes elapses after a massage part is driven, time is up in the timer 8b and the control part 8a resets the whole system. Besides, when the over- current detecting circuits 7 detect the over-current, time is forcibly up in the timer 8b and the control part 8a resets the whole system. By the configuration, an accident owing to the over-load such as motor over-heating and finger catching is prevented and safety is improved.
