Abstract
When telescopic locking is released, a second tooth defining member interlocked with rotation of a clamping shaft via an interlocking mechanism (a driving member and a coupling shaft) acts to separate second teeth of the second tooth defining member from first teeth arranged in a column axial direction. At this time, the second teeth rotate in a circular-arc-like trajectory around a central axis of a support shaft, while the support shaft itself slides through a long groove formed in an outer jacket in the column axial direction. Thus, the movement trajectory of the second teeth during release of meshing engagement is in a direction approximately orthogonal to the column axial direction (the direction in which the first teeth are arranged).
