ABSTRACT:
A portable vibration finger pressure massager provides finger pressure massage to a body part of the user through the turning motion of massaging balls when the motor rotates in a first direction and simultaneously provides vibration and finger pressure massage when the motor rotates in an opposite direction. A weight change structure is attached to the rear shaft of the motor and becomes unbalanced when the motor rotates in the opposite direction, thereby causing the motor to vibrate. The vibration of the motor is transferred to projections provided on the massager thereby enabling the provision of vibration massage.
