Abstract: A steering column includes: a cylindrical member that holds a steering shaft in such a manner as to allow extension and contraction of the steering shaft; a holding member that holds the cylindrical member; a fixture member that is fixed to a vehicle body; a coupling member that couples the fixture member and the holding member; and an energy absorbing member that is partially fixed to the holding member. The coupling member uncouples the fixture member and the holding member when the holding member moves forward for a specified distance in an axial direction. The fixture member has an engaging section arranged at a position where the engaging section is engaged with an engaged section of the energy absorbing member when the holding member moves forward for the specified distance or longer in the axial direction.

Abstract: On the outer peripheral surface of a part of a tilt operation shaft between sidewalls of a steering column, a pair of left and right protrusions are disposed opposite to each other which protrude outward in the radial direction. The pair of protrusions include mutually facing side surfaces formed as slanted parts defining a truncated V shape in a plan view such that the slanted parts get closer to each other as extending in the circumferential direction of the tilt operation shaft. When the tilt operation shaft is rotated, parts of a spring come into contact with the slanted parts of the protrusions and become elastically deformed, thereby pulling hold end parts of the spring out of tilt holes in wall surface parts of a tilt bracket.

Abstract: A steering column device includes: an outer column having a tubular shape; an inner column movably inserted in the outer column; a restricting member provided through a tubular wall at a lower section of the outer column in such a way as to be capable of coming in and out of the tubular wall in the thickness direction thereof; and a load absorbing wire including first ends engageable with the restricting member and a second end supported on the inner column side, and configured to be deformed by movement of the second end toward the vehicle front side together with the inner column upon application of a load of a preset value or greater to the inner column toward the vehicle front side, to thereby absorb the load.
