ABSTRACT:
A tilt steering apparatus for vehicles includes a fixed bracket and a rotational bracket rotatably mounted on the fixed bracket and having a ratchet fixed on a side thereof. A pawl, pivotally mounted on the fixed bracket, engages the ratchet when the rotational bracket is in an upward position and in a downward driving position. Memory means memorizes a selected engagement relationship between the pawl and ratchet when the pawl and ratchet are engaged and the rotational bracket is in a downward position. When the rotational bracket is subsequently being rotated to the downward position, intermediate means maintain the ratchet and pawl in a disengaged state until the rotational bracket is in the downward driving position.
