Title:
DAMPER DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/066030
Kind Code:
A1
Abstract:
An input element, first and second intermediate elements and an output element of a damper device respectively include a torque exchanging portion for exchanging torque with any corresponding resilient body from among first, second, third, fourth and fifth resilient bodies, and at least any one of the torque exchanging portions receives a centrifugal force acting on the corresponding resilient body via a protrusion inserted into an end portion of the resilient body. This makes it possible for hysteresis in the damper device to be reduced further and for the vibration damping performance thereof to be improved further.
