PROBLEM TO BE SOLVED: To provide a portable massage device which reduces vibration transmitted to user's hand. SOLUTION: The portable handy massage device for medical treatment 10 includes a vibrationless motor 20 which has an output axis 64 directly connected with a vibrator head assembled body 14. Rotating movement of the output axis 64 is converted into a vibration orbit movement around the shaft's center line in the vibrator head assembled body 14 by an offset cam formed as a part of an eccentric material with a balance weight. The balance weight provided with the eccentric material reduces vibration transmitted to a user's hand and insulates vibration of the vibrator head assembled body 14. The installing structure between vibrating adapter parts and the still part of the vibrator head assembled body 14 fixed with the motor 20 prevents the vibrator head assembled body 14 from rotating unnecessarily. |
