Abstract
A steering operation input apparatus is for allowing a predetermined neutral position to be acquired regardless of a direction in which a nut is mounted. In a mechanical stopper mechanism, a central position of the nut in an axial direction aligns with a central position of a crest and a central position of a root of an externally threaded portion with a steering wheel in a neutral state. A first imaginary line extends in a direction perpendicular to a rotational axis and passes through the crest and the root, and a second imaginary line extends perpendicularly to the first imaginary line on a line of the rotational axis in a cross section perpendicular to the rotational axis at the central position of the nut, and a pin is symmetric about the first imaginary line and asymmetric about the second imaginary line.
