Abstract
A gear backlash adjusting mechanism includes a worm wheel having a gear tooth that engages the gear tooth of a worm. The gear tooth of the worm wheel is curved or tapered upwardly in the axial direction toward one end of the worm wheel. An adjusting apparatus permits the distance between the gear tooth of the worm wheel and the gear tooth of the worm to be adjusted so that the amount of backlash between the gear tooth of the worm wheel and the worm can be adjusted.
