STEERING LOCK DEVICE

In a steering locking device comprising a locking device for automatically locking a steering shaft when a key of an ignition switch is withdrawn in a state in which the key is withdrawable, a key mechanism section and the locking device of the ignition switch are provided separately, and the locking device is provided at any portion on an output shaft of a steering wheel extending from the steering wheel to a steering gear section. Accordingly, a large space around knees can be secured while securing a sufficient collapse stroke, and a good steerability is maintained by preventing resonance of the steering wheel caused by lowering of a natural frequency vibration of a steering column while reducing the weight of the device.
