To provide low-cost steering device that can quickly execute a tilt adjustment, a telescopic adjustment and a retractable operation by combining two actuators with a crank mechanism, and to provide a steer-by-wire type steering system.SOLUTION: A steering device includes: a fastening bracket 12 attached to a vehicle body; a steering shaft 20; and a steering jacket 30 that internally supports the steering shaft 20 so as to be freely rotatable. This steering device further includes: a first actuator 70 which is placed between the fastening bracket 12 and a lower column 32, and which displaces the lower column 32 in the axial direction; a second actuator 80 which is placed between the lower column 32 and an upper column 31, and which displaces the upper column 31 in the axial direction; and a crank mechanism 43 which is placed between the lower column 32 and a swing column 40, and which causes the swing column 40 to swing in accordance with the relative displacements of the upper column 31 and of the lower column 32 in the axial direction.SELECTED DRAWING: Figure 2

    【課題】2つのアクチュエータとクランク機構を組合せることで、チルト調整、テレスコ調整、及びリトラクタブル動作を素早く行うことができる、低コストなステアリング装置及びステアバイワイヤ方式のステアリングシステムを提供する。【解決手段】車体に取付けられる固定ブラケット12と、ステアリングシャフト20と、ステアリングシャフト20を内側で回転自在に支持するステアリングジャケット30と、を備え、固定ブラケット12とロアコラム32間に配置されて、ロアコラム32を軸方向に変位させる第1アクチュエータ70と、ロアコラム32とアッパーコラム31間に配置されて、アッパーコラム31を軸方向に変位させる第2アクチュエータ80と、ロアコラム32と揺動コラム40との間に配置されてアッパーコラム31とロアコラム32の軸方向の相対変位に応じて、揺動コラム40を揺動させるクランク機構43と、を備える。【選択図】図2
