A fastening mechanism fastens a first side plate to a second side plate by a fastening member. A boss with a rhombic cross-section of the fastening member is inserted into a telescopic-adjust long groove of the second side plate. An outer periphery of the boss includes a first corner part and a third corner part each forming an obtuse angle and facing each other. The first corner part is disposed on an upper side in an axial direction, on a lower side in a tilt direction, while the third corner part is disposed on a lower side in the axial direction, on an upper side in the tilt direction. A width across the first corner part and the third corner part is shorter than a groove width W of the telescopic-adjust long groove.

Steering device

A first plate of a stationary bracket has long holes which extend parallel to a column movement direction, and through which large-diameter portions of suspension bolts are passed. The inner circumferences of the long holes include: recessed curved surface portions of end portions in a direction opposite to the column movement direction; first inner edge portions which are on the side of a middle position between the long holes; and second inner edge portions. In a secondary collision, when the one suspension bolt slides over the first inner edge portion of the long hole, for example, a gap is formed between the other suspension bolt and the second inner edge portion of the long hole.

Elongated holes are formed in a first plate of a fixed bracket so as to extend parallel to a column moving direction. An elongated hole inserted portion of a suspending bolt of a suspending mechanism is disposed in an initial assembling position in one of the elongated holes. An inner circumference of the elongated hole includes a pair of flat surface portions which are parallel to the column moving direction, an arc-shaped surface portion and tapered surface portions which connect a pair of end portions of the arc-shaped surface portion to the corresponding flat surface portion. Tapered angles which the tapered surfaces form relative to the column moving direction are equal to or greater than a friction angle.

A steering system includes a steering column which supports rotatably a steering shaft to which a steering wheel is connected and a pair of support mechanisms which support the steering column so as to tilt relative to a vehicle body. Each of the support mechanisms includes a support bracket having a column-side fastened portion and a body-side fastened portion, a fulcrum bolt, and a bush. A fastening hole through which a fastening bolt is inserted to fasten the support bracket to a fixed member is formed in the body-side fastened portion. Each of the support mechanisms includes an elastic member which can be compressed in an axial direction of the fulcrum bolt, and the support bracket is configured to oscillate relative to the steering column by the elastic member being compressed.
