To provide a tilt adjusting steering device which can be operated safely even when a steering wheel is tilted at a large angle beyond a tilt adjusting range during operation.
When the wheel is sprung up at a large angle, gear shifting is locked at a parking range (P) to inhibit the travelling of a vehicle as a fail safe mechanism and prevent the spring-up of the wheel during travelling. There provided a sensor 24 for spring-up at a large angle which detects that the front end support seat 22 of the rear column member 5 is contacted with the rear end support seat 21 of the front column member 4. When a vehicle travelling state such as the release of a handbrake and gear shift movement is detected after the rear column member 5 is returned to a normal tilt adjusting range (about ±10°), the pin 25a of a solenoid 25 provided in the rear column member 5 enters in the locking hole 12b of a tilt adjusting lever 12 and locks the lever 12.
