Abstract:
1. A tilting and telescopic steering apparatus, comprising: a column housing surrounding a steering shaft; a telescopic tube coupled, on a first end thereof, to the column housing; a telescopic bracket surrounding a second end of the telescopic tube so as to slidably move along the telescopic tube; a tilt shaft provided in the telescopic bracket; a tilt bracket rotatably coupled to the tilt shaft so that the tilt bracket is rotated relative to the tilt shaft; an adjusting bolt provided in parallel with the tilt shaft and passing through one side of the telescopic bracket and the tilt bracket; a cam provided on one end of the adjusting bolt and contacting a circumferential face of the telescopic bracket; an adjusting lever driving the cam to move the adjusting bolt in an axial direction, such that a rotation of the adjusting lever along the axial direction in a first direction allows for a first axial movement of the adjusting bolt, and a rotation of the adjusting lever along the axial direction in a second direction counter to the first direction allows for a second axial movement of the adjusting bolt; and a tilt locking member provided on the other end of the adjusting bolt, the tilt locking member including a first mesh part on the telescopic bracket and a second mesh part on the adjusting bolt, the first mesh part being engaged with the second mesh part by the first axial movement of the adjusting bolt to lock the telescopic bracket and the telescopic tube, the second mesh part being separated from the first mesh part by the second axial movement of the adjusting bolt to unlock the telescopic bracket and the telescopic tube.
