Abstract
A steering wheel position adjusting apparatus including a fixed tubular column, a movable tubular column movably mounted on the fixed tubular column, a lower rotational output steering shaft mounted within the fixed tubular column, and an upper rotational input steering shaft mounted within the movable tubular column and having upper and lower ends. The upper rotational steering shaft is connected at the upper end thereof to the manually operated steering wheel, and is connected at the lower end thereof to an upper end of the lower rotational steering shaft. The upper rotational steering shaft is movable with respect to the lower rotational steering shaft. An annular shaped ultrasonic motor is mounted on the outer periphery of the fixed column, the annular shaped ultrasonic motor being coaxial with the fixed tubular column and includes an output gear. A movable tubular column position adjusting device is provided for moving the movable tubular column relative to the fixed tubular column by actuation of the annular shaped ultrasonic motor. The movable column position adjusting device includes input gear engaged with the output gear of the annular shaped ultrasonic motor, an output c…
