Title:
DAMPER DEVICE
Document Type and Number:
Japanese Patent JP2017067159
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To make rigidity of a damper device low by enlarging a maximum torsional angle of an input element with respect to an output element while enabling absorption of a larger torque variation.SOLUTION: An intermediate member 14 of a damper device 10 has an outside spring abutting parts 14co which support both ends of a third spring SP3 when torque is not transmitted between a drive member 11 and a driven member 15. The drive member 11 has outside spring contact parts 12co, 13co which do not abut on the ends of the third spring SP3 when the torque is not transmitted between the drive member 11 and the driven member 15. The outside spring abutting parts 12co, 13co abut on one end of the third spring SP3 accompanied with an increase of a relative torsional angle between the drive member 11 and the intermediate member 14 when the torque is transmitted between the drive member 11 and the driven member 15.SELECTED DRAWING: Figure 1
