Abstract
A damper assembly includes a driven plate, an intermediate plate, and elastic drive elements. The intermediate plate includes a radially outer base wall and opposite side walls. The elastic drive elements are interposed, between tabs of the driven plate and tabs of the intermediate plate to permit relative rotational movement therebetween. The elastic drive elements reside in cavities defined, in part, by a substantially annular radially inwardly facing surface of the intermediate plate. A first region of the radially inwardly facing surface in closest proximity to the elastic drive elements has a first radius. A second region of the radially inwardly facing surface axially interposed between the first region and the first side wall has a second radius that is greater than the first radius.
