Steering column device

A steering column device (1) is provided with: a lower tube (22) that is attached so as to be swingable in the vertical direction with respect to a vehicle body; a column shaft (2) for mounting a steering wheel (7); an upper tube (21) that rotatably supports the column shaft (2) and is mounted so as to be movable in the front-rear direction with respect to the lower tube (22); a motor (41) for generating a motor torque; a link mechanism (50) that links the lower tube (22) and the upper tube (21) in a freely interlocked manner; and a power transmission mechanism (42) that operates so as to transmit the motor torque to the link mechanism (50). The link mechanism (50) is configured so that, when the motor torque is transmitted to the link mechanism (50) by the power transmission mechanism (42), the link mechanism (50) operates so that the vertical swing of the lower tube (22) is linked with the forward/backward movement of the upper tube (21). 转向柱装置(1)具有：下管(22)，相对于车身在上下方向上摆动自如地安装；柱轴(2)，供方向盘(7)安装；上管(21)，将柱轴(2)支承为
