Title:
DAMPER
Document Type and Number:
Japanese Patent JP2019049305
Kind Code:
A
Abstract:
To provide a novel damper capable of suppressing torque fluctuation in a wider revolution-speed range, for example.SOLUTION: A damper in this invention includes a first rotation element rotatable around a rotation center, a second rotation element rotatable around the rotation center, a first elastic element laid between the first rotation element and the second rotation element and adapted to be elastically extended/contracted in a peripheral direction of the rotation center, a second elastic element laid between the first rotation element and the second rotation element in parallel to the first elastic element and adapted to be elastically extended/contracted in the peripheral direction, and an intermediate mass element provided at a midway position in the peripheral direction of the first elastic element. In this construction, as a torsional angle between the first rotation element and the second rotation element is larger, torsional torque given to the first rotation element and the second rotation element by the extension/contraction of the first elastic element shows a greater change rate per unit angle of the torsional angle.SELECTED DRAWING: Figure 7
