PURPOSE:To keep off any curve in the damper plate of a duplex double mass rubber damper as well as to prevent any variations in natural frequency from occurring. CONSTITUTION:In a duplex double mass rubber damper 10 which is provided with two inertial masses 12, 13 fixed to loath sides of a damper plate 11 via each of rubber members 14 and 15, and the member 14 lying between the damper plate 11 and the inertia mass 12 on one side is directly supplied in a metal mold, and the rubber member 15 on the other lying between the damper plate 11 and the inertia mass 13 on the other is supplied through plural vulcanized holes installed in the damper plate 11 as its formation, the inertia mass 12 on one side is concentrically provided with a slightly small diametral vulcanized hole 12d in response to each vulcanized hole 11d of the damper plate 11, and the rubber member is supplied from each vulcanozed hole 12d of the inertia mass 12 in the metal mold. |
