An adjustable steering apparatus (S) includes: a movable bracket (3) to which a steering jacket (1) including a steering wheel (2) is fixed and to which a movable telescopic member (9) having a tooth portion (9a) is fixedly mounted; a stationary bracket (4) which is disposed externally of the movable bracket (3) and fixed to a vehicle body, and to which a stationary tilt member (10) having a tooth portion (10a) is fixedly mounted; a movable tilt member (12) having a tooth portion (12a) meshingly engageable with the tooth portion (10a) of the stationary tilt member (10); and a stationary telescopic member (11) having a tooth portion (11a) meshingly engageable with the tooth portion (9a) of the movable telescopic member (9). An elastic body (13) for release from meshing engagement is disposed on an outer side of the stationary bracket (4), the elastic body (13) being capable of urging the movable tilt member (12) away from the stationary tilt member (10). The movable tilt member (12) is engageable with the stationary telescopic member (11) in order that the movable tilt member (12) being disengaged from the stationary tilt member (10) can bring the stationary telescopic member (11) out of engagement with the movable telescopic member (9).
