In a tilt steering column assembly, there is provided a tilt lock mechanism comprising upper and lower toothed bars which extend along the column assembly, and which are formed with teeth like a rack, and swingably supported by upper and lower steering columns, respectively. The bars are both placed between two side walls of a lock member having inclined cam slots for moving the bars into and out of engagement. The toothed bars are engaged with each other to lock the tilt steering column assembly securely at a selected tilt position.
