ABSTRACT:
An ignition distributor rotor that is formed of electrical insulating material. The rotor has a retainer portion that is adapted to be pressed onto the end of a distributor drive shaft. This retainer portion has an axially extending wall that has an undulated shape defined by circumferentially spaced undulated portions. The inner surfaces between the undulated portions tightly engage outer surface portions of the shaft. One of the undulated portions is located in a slot in the shaft to form a driving connection between the shaft and the rotor. The retainer portion has a plurality of flexible circumferentially spaced latch arms. The ends of the latch arms are shaped to enter an annular groove on the distributor shaft to thereby lock the rotor from a axial movement relative to the distributor shaft.
