A gear assembly comprising two gears and a spring in the form of a C-shaped clip interconnecting the two gears. Two pins are provided on one of the two gears and the spring has two holes, one in each end thereof, whereby the spring can be carried by one gear in a pretressed state by means of the pin-and-hole connection. The other gear has a groove to cover the spring, thus the assembly work can be accomplished simply by resting the second gear to the first gear. An end wall of the groove engages with an end of the spring to create a spring force necessary to provide non-backlash mating with a third gear.
