Abstract: A massager which comprises a moving bed disposed above a frame so as to be movable in the longitudinal direction of said frame, a plurality of massaging rolls disposed underneath said moving bed and rotary-reciprocal motion conversion means adapted to drive said moving bed and said massaging rolls by the media of drawing means and rotating means. A motion imparted to the rotary-reciprocal motion conversion means causes said moving bed to produce a reciprocating motion and said massaging rolls to produce a rotating motion, with the result that a massaging effect is brought out on the body of a patient lying on the moving bed.
