ABSTRACT:
An electric power steering apparatus includes a gear wheel on a driven side having a gear portion on one side surface thereof on a steering shaft and a pinion to be laterally meshed with a gear portion of the gear wheel on a shaft capable of transmitting a rotational driving force from an electric motor. The gear wheel and the pinion constitute a gear mechanism for transmitting a rotational force as a gear pair with non-parallel, non-intersecting axes. The gear wheel is axially supported on the steering shaft so as to be coupled in only a rotational direction and movable in an axial direction of the shaft. A biasing unit is provided on the other side of the gear wheel opposite to a portion of the pinion to be meshed with the gear portion and laterally urges the gear wheel toward the pinion.
