A gear includes an annular sleeve and a tooth portion provided by injection molding to cover a part of the sleeve. The sleeve is a stacked body including a plurality of annular steel plates stacked in an axial direction of the sleeve.

Gear and steering device

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.
