A steering column device includes a steering column; and a telescopic actuator. The steering column includes a first column member, a second column member assembled to the first column member in a manner of being displaceable relative to the first column member in an axial direction, and a low-friction sliding member disposed between the first column member and the second column member. The telescopic actuator includes a telescopic motor, and displaces the second column member in the axial direction with respect to the first column member by using the telescopic motor as a drive source.

A system for adjusting a rake of a steering column includes a rake actuator. The system also includes a jacket assembly. The system further includes a first bracket operatively coupled to the jacket assembly, the first bracket defining a first slot. The system yet further includes a second bracket defining a second slot, the second bracket fixed in a stationary position relative to the first bracket, the first and second slots oriented at different angles, but partially aligned. The system also includes a cam follower operatively coupled to the rake actuator, the cam follower having an arm extending through the first slot and the second slot, wherein translation of the cam follower adjusts the angular position of the first bracket and the jacket assembly.

A steering device includes a column housing encapsulating a steering shaft and enabling a posture change, a bracket located adjacent to the column housing, and a tensioner mechanism being between the column housing and the bracket, and pressing the column housing and the bracket. The tensioner mechanism includes a casing provided in the column housing or the bracket, a tensioner main body being provided in the casing, and being movable in a direction intersecting a facing direction of the column housing and the bracket, and a biasing member biasing the tensioner main body. The tensioner main body includes a first surface facing toward the column housing, and a second surface facing toward the bracket. The first surface and the second surface are configured to be in a tapered shape in which a space therebetween becomes narrower as closer to a lower side of a biasing direction.

A steering column device includes: a link mechanism pivotably supported with respect to a fixing bracket about a first pivot shaft, which is perpendicular to a center axis PC of a steering shaft and is positioned further toward an upper side of a vehicle than the center axis PC, and pivotably supported with respect to a column jacket about a second pivot shaft, which is positioned further toward the upper side of the vehicle than the center axis PC; and a drive mechanism connected to the link mechanism to drive the link mechanism, thereby adjusting a tilt angle of the steering shaft. A sliding member includes a shaft member engaged in an elongated hole which is provided in a portion of the link mechanism which is near the second pivot shaft, and the shaft member is pivotably supported in the elongated hole and fixed to the column jacket.

A gear housing for an electric power steering device has a front-side housing and a rear-side housing. The front-side housing has a worm wheel housing portion, a worm housing portion, and reinforcing ribs. The worm wheel housing portion has a worm wheel cylindrical portion and a ring shaped worm wheel bottom portion bent inward in a radial direction from a front end portion of the worm wheel cylindrical portion. The worm housing portion is provided on a part in a circumferential direction of an outer-diameter side portion of the worm wheel housing portion. The reinforcing ribs are provided on a front side surface of the front-side housing, extend in a direction in which an engagement reaction force acts between the worm wheel and a worm of the worm shaft, and span between the worm housing portion and the worm wheel bottom portion.

A steering device includes a steering wheel, a steering shaft, a steering column, a tilt position adjustment mechanism for tilting the steering column, and a joint for tiltably connecting the steering shaft with a fixed-side rotating body which is supported on a vehicle body side without being interlocked with a tilt operation performed by the tilt position adjustment mechanism. The joint is disposed closer to a steering wheel side than the fixed-side rotating body is.

The tensioner mechanism includes a casing provided in the column housing or the bracket, a tensioner main body being provided in the casing, and being movable in a direction intersecting a facing direction of the column housing and the bracket, and a biasing member biasing the tensioner main body. The tensioner main body includes a first surface facing toward the column housing, and a second surface facing toward the bracket. The first surface and the second surface are configured to be in a tapered shape in which a space therebetween becomes narrower as closer to a lower side of a biasing direction.

An adjustment lever deceleration assembly for a steering column includes an adjustment lever rotatable between a locked position and an unlocked position. The adjustment lever deceleration assembly also includes a component positioned proximate the adjustment lever, the component rotating at a speed less than a rotational speed of the adjustment lever during adjustment between the locked position to the unlocked position. The adjustment lever deceleration assembly further includes an adjustment lever decelerator integrally formed with the adjustment lever, the adjustment lever decelerator positioned on the adjustment lever to contact the component during rotation of the adjustment lever toward the unlocked position, wherein the adjustment lever deflects and absorbs energy upon contact with the component.

A steering column having an adjustment limit stop device comprising a body receiving, in a deformable bearing, the sleeve carrying the steering wheel and a mechanism for clamping a shaft with a lever carrying a clamping device compressing the deformable bearing. The steering column comprises a stop device provided with a stop edge carried by the sleeve and with which a lock cooperates that limits the adjustment travel of the sleeve while being retracted after the adjustments of the column have been clamped, allowing the sleeve to travel, in the event of an impact on the steering wheel, in order to absorb the energy.
