Document Type and Number:
WIPO Patent Application WO/2018/051705
Kind Code:
A1
Abstract:
Provided is a damper device configured so that the force of impact acting on a stopper mechanism is reduced to enable each member to be configured as a low-cost member. This device is provided with a first flywheel (11), a second flywheel (12) which can rotate relative to the first flywheel (11), and an elastic unit (13) which has a first spring (31) and a second spring set (32). The elastic unit (13) further has a pair of first spring seats (41) and a plurality of second and third spring seats (42, 43). The springs (31, 32) are arranged between the first spring seats (41) in the circumferential direction, and the first spring seats (41) engage with the first and second flywheels (11, 12). The second and third spring seats (42, 43) are arranged between adjacent springs (31, 32) in the circumferential direction, have stopper sections for preventing the relative rotation between the first and second flywheels (11, 12) through an angle greater than or equal to a predetermined angle, and have lower rigidity than the first spring seats (41).
