Abstract

In a steering lock device of a type which can unlock a steering shaft of a vehicle without using a key, there is provided a so-called 'back-up' means for assuring the steering shaft unlocking condition of the device when the key in a key rotor assumes 'ignition ON' position. The means comprises a pivotally supported check lever having a first end projectable into the key rotor and a second end lockably engageable with a steering shaft locking bar. When the keyless unlocking is intended, the first end of the check lever is moved away from the key rotor by an electromagnetically actuated plunger thereby permitting rotation of the rotor toward the ON position disengaging the locking bar from the steering shaft. Upon completion of disengagement of the locking bar from the steering shaft, the second end of the check lever is brought into locking engagement with the locking bar thereby holding the same in the steering shaft unlocking condition.
