Steering device

A steering device comprising:

• a cylindrical inner column that supports an input shaft connected to a steering wheel so as to allow the input shaft to be rotatable;
• a cylindrical outer column into which at least a part of the inner column is inserted;
• and
• a cylindrical lower column that supports an output shaft connected to the input shaft so as to allow the output shaft to be rotatable and is supported by a dash panel,
• a first hole that is provided in the inner column;
• a first slit of the outer column that is formed by notching one end of the outer column, the one end being a side into which the inner column is inserted;
• an outer column bracket that is fixed to a vehicle body-side member and clamps and supports the outer column together with holding force-increasing members;
• an inner column bracket which is supported by the holding force-increasing members and in which a second hole is formed;
• and
• a shear pin that connects the inner column bracket to the inner column at a position across the first and second holes so that the inner column bracket and the inner column are detachable from each other,
• wherein the lower column moves to a rear side at the time of a primary collision, and the inner column and the outer column move relative to each other at the time of a secondary collision, and
• wherein an inner wall of the outer column is in contact with an outer wall of the inner column in a state in which the outer column is clamped, and a telescopic position of the inner column is adjustable in a state in which the clamping of the outer column is released.
