Abstract
An apparatus for limiting the amount of torque from a drive source applied to a torque responsive element in which a pair of rotatable cam plates have opposing faces formed with radially extending grooves. A plurality of angularly spaced balls are provided for respectively engaging within the opposing ramp grooves. A retainer plate is sandwiched between the opposing cam plates, with angularly spaced holes for freely receiving and radially retaining the balls. The retainer plate has periheral walls for surrounding, journalling and piloting the cam plates.
