本数が限られているからである。A. The pulley part is provided for winding one end of an endless belt around the pulley part and transmitting rotational torque from the rotating shaft equipped with the damper to various auxiliary machines. However, the prior art has only one pulley section, and therefore it is not possible to wrap many endless belts around it. This is because the strength of the sheet metal cantilever pulley is not very strong and the axial length of the pulley is limited, so the number of endless belts that can be wound around one pulley is limited. This is because it is

A pulley part is provided in each of the first vibration ring and the second vibration ring made of sheet metal, and the number of the pulley parts installed is two. In addition, a rubber mass replenisher is bonded to this pulley portion to replenish inertial mass and suppress the generation of radiated sound. The reason why the pulley part can suppress the generation of radiated sound is that the pulley part is made of rubber and has a sound absorbing effect.

ある。 As shown in FIG. 1, the torsional damper includes a hub 1 made of cast iron, a first cylindrical portion 2a disposed on the outer peripheral side of the hub 1, and a first pulley portion connected to the first cylindrical portion 2a via a first flange portion 2c. A first vibration ring 2 made of a sheet metal integrally molded with a vibration ring 2b, an elastic body 3 made of rubber vulcanized and bonded to the outer peripheral surface of the hub 1 and the inner peripheral surface of the first cylindrical part 2a, and a first cylindrical part 2a. A second vibrating ring made of sheet metal, in which a second pulley part 4b is integrally molded via a second flange part 4c to a second cylindrical part 4a fitted with a predetermined tightening margin on the outer peripheral side of the part 2a. 4, and a rubber mass replenisher 5 vulcanized and bonded to the inner peripheral surface of the first pulley portion 2b. The reason why the second cylindrical portion 4a is fitted onto the outer circumferential side of the first cylindrical portion 2a with a predetermined interference is that the fitting causes the first cylindrical portion 2a to be plastically deformed in diameter, and the deformation This is to compress the elastic body 3 in the radial direction and increase the durability of the elastic body 3.
