Abstract
A vehicle steering apparatus includes a variable gear ratio mechanism which is provided in a steering force transmitting system, and a lock mechanism which restricts relative rotation of an input shaft and an output shaft of the transmitting ratio changing mechanism. The lock mechanism is engaged by inserting a lock arm in a indented portion of a lock holder of the lock mechanism. A play angle when the lock mechanism is engaged by inserting the lock arm in the indented portion is set to be smaller than a rotational angle of a motor which is required for outputting six different signals.
