The cam assembly comprises an inner cam axially connected to the drive shaft. An outer cam disposed within the ring-like sliding member in co-planar relationship, a bearing interposed between the inner cam and the outer cam to transmit movement therebetween, and a needle bearing providing contact between the outer cam and the inner surface of the sliding member.
