Abstract
A shock-absorbing tilt type steering column is disclosed. An upper clamp includes a first side wall and a second side wall formed respectively with a first hole and a second hole. A coupler is inserted into the first and second holes. The first and second side walls have such a height that lower ends are disposed on a level with or above a lowermost section of a column jacket when the coupler is disposed in uppermost positions of the first and second holes. A distance bracket coupling with the column jacket is so sandwiched between the first and second side walls as to move upward and downward, and engages with the coupler in such a manner as to disengage from the coupler when a load over an upper limit is applied in a direction along the column jacket. An energy absorber is interposed between the distance bracket and the coupler.
