Abstract
A tilt adjustable type steering apparatus for a vehicle according to the present invention has a failsafe mechanism that makes the vehicle unable to travel by locking, e.g., a speed-change shift at a parking range (P) when a steering wheel is tilted up through a large angle, and prevents the steering wheel from being tilted up when other than parking of the vehicle, e.g., during the traveling. The present tilt adjustable type steering apparatus for the vehicle is provided with a large angle tilt-up sensorfor detecting that a front side end support seat portion (a tilt-up stopper)of a rear column memberabuts on a rear side end support seat portion (a tilt-up stopper)of a front column member. When detecting a vehicle travelable state such as a release from a parking brake, a shift-down or shift-up of the change gear, etc. after the rear column memberhas returned to within a normal on-driving tilt adjustable range (approximately ±10 degrees), a pinof a solenoidprovided on the rear column memberenters a lock holeof a tilt adjusting lever, thereby locking the tilt adjusting lever
