Abstract
According to the present embodiments, locking and unlocking can be smoothly performed even when gears for fixing a steering column during a telescoping operation of the steering column are not properly engaged, a collapse motion for absorbing impact can be smoothly performed even when a vehicle collision occurs in a state in which the gears are not properly engaged, impact is absorbed at the minimum and maximum of strokes so as to enable the prevention of noise generation during the telescoping operation, and the number of components can be reduced and assembly process can be simplified.
