Abstract: A torsional vibration damper has a hub part (primary mass) that is able to be fastened to a driveshaft of a motor, and an inertia ring (secondary mass) that surrounds the hub part in the radially outer region, wherein a fluid-filled gap and sealing devices, by which the escape of the fluid is intended to be avoided, are provided between the hub part and inertia ring. The sealing devices each have a first ring, tightly connected to the hub part, and each have a second ring, tightly connected to the inertia ring, and each have a sealing element made of an elastomer, which is connected in each case sealingly to the first ring on one side and in each case to the second ring on the other side. The damper is configured such that the respective sealing element has been vulcanized onto a respective external axial side of the first and second ring by fastening portions.
