The steering wheel includes a wheel body and an airbag apparatus disposed
on top of a boss. The wheel body is divided into a shaft side division
joined to the steering shaft, and a ring side division disposed proximate
the ring. The ring side division is rotatable with respect to the shaft
side division such that a ring plane is aligned generally vertically. The
boss includes an actuator that rotates and moves the ring side division
to align the ring plane generally vertically. The actuator completes its
operation to align the ring plane generally vertically by the time a
driver contacts the inflated airbag in the course of forward motion.
