DAMPER DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/043528
Kind Code:
A1
Abstract:
Provided is a damper device configured so that, even if torsional vibration is large, an end of a damping mechanism will not wear. This damper device comprises: a disc body 10; a shaft 20 disposed at the center of rotation of the disc body 10 in a relatively rotatable manner; a first intermediate element 30 and a second intermediate element 40, which are positioned between the disc body 10 and the shaft 20 in a relatively rotatable manner; a damping mechanism (50) provided between the first and second intermediate elements (30, 40); a disc-side restriction section (14) for restricting the rotation of the first and second intermediate elements (30, 40); a shaft-side restriction section (21) in contact with one or both of the first and second intermediate elements (30, 40) to restrict rotation; a shaft-side guide section (304) of the first intermediate element (30), which restricts the range of relative rotation of the first intermediate element (30); and a shaft-side guide section (404) of the second intermediate element, which restricts the range of relative rotation of the second intermediate element (40).
