Document Type and Number:
Japanese Patent JP2020046019
Kind Code:
A
Abstract:
To provide a torsional damper which can cool a rubber elastic body directly, enables improvement of heat radiation efficiency, and inhibits component costs from increasing extremely.SOLUTION: A torsional damper 1 includes: an annular hub 11; a vibration ring 51 disposed coaxially with the hub 11; rubber elastic bodies 41 which are disposed between the hub 11 and the vibration ring 51 and to which the hub 11 and the vibration ring 51 are coupled; and multiple heat radiation protrusions 42 on a circumference, each of which is integrally provided with axial end parts of the rubber elastic body 41. The heat radiation protrusions 42 are respectively provided at both axial end parts of the rubber elastic body 41.SELECTED DRAWING: Figure 1
