The key interlock device consists of the ignition key
cylinder, interlock cable and the lock cam installed
inside the selector handle. The lock cam is inter-
locked with the detent pin and their movement is

the hook inside the ignition key cylinder is
positioned that it does not interfere with the

position or it is pulled out, the projection of
the rotor moves to the position where it
prevents the hook inside the key cylinder
from moving. Therefore, even if an effort is
made to depress the push button of the shift
lever, the lock cam prevents the detent pin
from moving and the shift lever cannot be
shifted to the positions other than the "P"

position
When the shift lever is in the positions other
than the "P" position (for example. "N" posi-
tion), the lock cam turns clockwise and held in
that .state as shown in (2) of the illustration.
Therefore, the key interlock cable is in a stroked
state, with the hook inside the ignition key
cylinder inserted in the notch made in the
projection of the rotor. Thus, even if it is
attempted to return the ignition key to the
"LOCK" position, the hook prevents the rotor
from turning and the ignition key can be turned
only up to the ACC position, making it impossi-
ble to pull out the key.
