A pad type roller massager comprising an upper supporting bracket and a lower supporting brackets, an upper bracket cover and a lower bracket cover, a driving mechanism, a guiding column A, a sliding block, an eccentric motor, a positioning cover for motor, a position controller, a plurality of screws S, and a rollers assembly is provided. The upper and lower supporting brackets are connected by those pair of guiding column which are parallel with each other. A sliding block is moveably attached to the guiding columns and may move upward and downward along the guiding columns. The upper supporting bracket is enclosed with an upper bracket cover and the upper supporting bracket is rotationally disposed with a pulley therein. The lower supporting bracket is also enclosed with a lower bracket cover and the lower supporting bracket is disposed with a worm gear motor which in turn meshed with a worm gear having a pulley formed thereof. A belt is guided via the pulley and the worm gear having pulley. The free end of the belt are fixedly attached to the sliding block. Consequently, when the worm gear motor is rotated, the belt as well as the sliding block is moved upward and downward. The sliding block is further provided with a position controller which can reverse the rotating direction of the worm gear motor when the controller reach to the upper or lower supporting brackets. A plurality of rollers assemblies are carried by the sliding block and which may exert a massaging movement to the muscle when the rollers assemblies are moved along the guiding columns. The sliding block is further provided with an eccentric motor which provides vibration to the sliding block. As a result, the massager is featured with a three dimensional massaging movement.
