A second toothed member is configured to change its position between a meshing position where first teeth mesh with second teeth and a meshing releasing position where the first teeth do not mesh with the second teeth. A first toothed member and a facing member move together with an upper jacket. The second toothed member located at the meshing position receives an impact from the first toothed member so as to collide against an impact absorbing member after rupture of a guide shaft and deform the impact absorbing member. The second toothed member located at the meshing releasing position receives an impact from the facing member so as to cause rupture of the guide shaft and deformation of the impact absorbing member to occur concurrently.

Steering system

A steering apparatus includes a gear lock mechanism that fastens a first side plate to a second side plate by a fastening member. In a lock operation, a main body of the fastening member of a fastening mechanism presses a second tooth row forming member toward the first side plate, and a guided projection of the fastening member rotates slightly in the range of play in a lock direction. The fastening member slightly rotates the second tooth row forming member in the lock direction via a restricting portion. During the slight rotation, a second tooth row of the second tooth row forming member is aligned with and meshes with a first tooth row of the first side plate.
