A tilt adjusting unit for steering columns prevents a steering column (20) from popping up due to an external impact. The tilt adjusting unit includes a support bracket (31,32) mounted to a predetermined portion of a vehicle body. A steering column (20) is mounted to a predetermined portion of the vehicle body to tilt relative to the vehicle body. A movable bracket (40) tilts along with the steering column (20). A connection rod (50) connects the movable bracket (40) to the support bracket (31,32). A guide slot (33) is formed on a predetermined portion of the support bracket (31,32) along a tilting direction of the steering column (20), with the connection rod (50) passing through the guide slot (33). A locking unit (60) is provided on a predetermined portion of the connection rod (50) to lock or unlock the movable bracket (40) to or from the support bracket (31,32). A crossing plate (100) is mounted to a predetermined portion of the support bracket (31,32) to rotate around an end of the crossing plate (100), and has a crossing slot (101) to cross the guide slot (33), thus allowing the connection rod (50) to pass through both the guide slot (33) and the crossing slot (101). <IMAGE>
