Means to prevent flutter of the interleaved clutch plates of a clutch including clutch plates having their peripheries formed as non-circular members. The outer periphery of the clutch plates are formed with flat portions or spots which act as cams when the adjacent discs rotate relative to each other and whereby they resist the tendency to flutter. The clutch plates are formed so that a continuous circular surface no longer exists on the periphery of the plates and in effect a series of cams are provided which tend to drive the clutch plate to a neutral or no-force position.
