Abstract
A steering column device includes a lower tube that is attached to a vehicle body so as to be pivotable in an up-down direction, a column shaft to which a steering wheel is attached, an upper tube that rotatably supports the column shaft and that also is attached to the lower tube so as to be movable in a front-rear direction, a motor for generating motor torque, a link mechanism that couples the lower tube and the upper tube so as to be capable of moving in conjunction, and a power transmission mechanism that acts to transmit the motor torque to the link mechanism. The link mechanism causes the pivoting of the lower tube in the up-down direction and the movement of the upper tube in the front-rear direction to be performed in conjunction, when the motor torque is transmitted to the link mechanism by the power transmission mechanism.
