ABSTRACT:
A connection structure between a plastic gear and a shaft permits easy phase matching relative to a device mounted on the shaft, and easy meshing of a gear provided on the shaft with another gear. The connection structure includes a plastic gear, a shaft, and a set plate. The plastic gear has a geometric recess which receives the correspondingly-shaped set plate therein. The set plate includes a central shaped opening. The shaft is provided with a mating extension extending from a first end, and which fits within the shaped opening. The mating extension is formed such that the plastic gear may be mounted thereon in a first position wherein the plastic gear is not positioned to interact with a mating gear, and the plastic gear can be slidably moved thereon to a second position such that the plastic gear is positioned to interact with the mating gear.
