PURPOSE: A manufacturing method of a torsional damper is provided to enable manufacturing and installation to be conveniently performed since after a damping member is arranged in a housing and a fixing plate, the damping member is melted to manufacture the torsional damper. CONSTITUTION: A manufacturing method of a torsional damper is as follows. A housing of a cup shape is prepared, wherein a crank shaft is coupled to the outer surface of one side of the housing, and the other side is open to form an inner space(S11). A hub, comprising a central part of a cylinder shape and a flange, is inserted into the inner space, wherein a connecting shaft is coupled to one end of the central part, and a flange is coupled to the other end of the central part(S12). A circular fixing plate is prepared, wherein an insertion hole is formed on the central part of the plate, and an injection hole is formed on its one side(S13). The central part is inserted into the insertion hole and the fixing plate is fixed to the other surface of the housing(S14).
