Abstract
The armature assembly (9 or 17) includes a hub (10 or 19) adapted to be connected to and rotate with an input shaft (8 or 18). The hub (10 or 19) includes a flange (10a or 19a) connected to a composite material armature support plate (12 or 21). Rubber dampers (15 or 23) are molded to rivets (14 or 24) and are pressed into cylindrical peripheral walls (12a or 21b) of damper holder sections (13 or 22). The rivets (14 or 24) are staked to an armature (16 or 25). The rubber dampers (15 or 23) bias the armature (16 or 25) into contact with surface of a stopper (10e or 21g) when an electromagnetic clutch (1) is not energized and a space (G or G.sub.2) is formed that extends axially from the armature (16 or 25) to the armature support plate (12 or 21) and radially outward from the stopper (10e or 21g).
