Neutral position indication mechanism
The system comprises of a ring gear (number of teeth:
90) provided in the upper case, a transparent cover
mounted on the rotor with screws, and a gear (number of
teeth: 80) which is in mesh with the ring gear and is
driven by the convex portion of the cover.
The upper case is mounted on the steering column and
is always held in position.
The rotor is coupled with the steering shaft and always
operates with the steering wheel. The gear is always
kept in mesh with the ring gear by the convex portion of
the cover. If the rotor turns through a rotation, the
convex portion of the cover also turns through a rotation.
So the gear is displaced in the opposite direction to the
Convex portion to

Markings R2, 1, NEUTRAL, 1, and 2L are made on the
gear for every 10 teeth. An alignment mark is made on
the upper case. The clock spring is placed in the neutral
(straight ahead) position by lining up the alignment mark
with the mark NEUTRAL of the gear. The mark "R" on
the gear indicates that the rotor has been turned
clockwise, whereas the mark "L" indicates counter-
clockwise rotation of the rotor.
