Title:
DAMPER DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/037124
Kind Code:
A1
Abstract:
Provided is a damper device which is capable of inhibiting: the breakage of sandwiching protrusions of a spring sheet made of resin; and the occurrence of attachment failure of the sandwiching protrusions to a rotational-body attachment part. This damper device is provided with a second spring sheet (42) which is made of resin, and which supports both ends of first and second coil springs (31, 32) provided between a hub plate (1) and an input/output plate (2) in a peripheral direction, said damper device being characterized in that: the second spring sheet (42) is provided with a pair of sandwiching protrusions (46, 46) which protrude from a seat part (43) provided with a spring seat surface (43a), so as to be capable of sandwiching an attachment part (24b) of an intermediate-plate-side support arm (24); a side of each of the sandwiching protrusions (46), said side being located further towards the device exterior in a radial direction than a spring central axis (Sc), is configured as a low-rigidity part (46a) having a relatively low rigidity; and a side of each of the sandwiching protrusions (46), said side being located further towards the device interior in the radial direction than the spring central axis (Sc), is configured as a high-rigidity part (46b) having a relatively high rigidity.
