Abstract: The invention concerns massage device including body which contains motor and massage head, where installation mechanism is located between the body and the massage head and said head includes application surface and two massage wheels located along two initial parallel longitudinal axes, which are separated and extend partially outside the application surface. The massage head includes to cause the two wheels to rotate in synchronization and in opposite directions so that, when seen in perpendicular plane to the two axes with the wheels toward the bottom, section of wheel located on the left which extends past the application surface turns counterclockwise and section of wheel located on the right which extends past the application surface turns clockwise. A wheel spacing adjustment system is designed to initially create a minimum distance between the wheels then to adjust the distance to reach a position of equilibrium.
