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 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.

Steering column device

A steering column device includes an inner tube, a housing, and a lock mechanism configured. The lock mechanism includes a first engagement member, a second engagement member, a first urging member, a second urging member, a cam member configured to rotate about a rotation axis extending in a direction in which the first urging member and the second urging member are arranged such that the second urging member serving as a follower is moved in the direction in which the first urging member and the second urging member are arranged to change a magnitude relationship between an urging force of the first urging member and an urging force of the second urging member, and an operation lever configured to operate the cam member.
