Abstract
A rotary drive transmitting mechanism comprises a drive plate, a driven plate operably connected to a flywheel, and coil damping springs operably interposed between the drive and driven plates. Each end of the coil spring carries a seat which engages the drive plate or driven plate. Each seat has a surface which impacts against the respective plate. The surface includes concave and convex portions which mate with respective convex and concave portions of the drive plate or driven plate. The concave and convex portions include elastic layers for suppressing noise. Elastic layers are also provided on other surfaces of the seats which face each other through the spring.
