To achieve smooth appearance and retreat of a steering member.SOLUTION: A steering gear 100 includes: a retaining mechanism 110 having a first shaft body 111 and a second shaft body 112 retaining the first shaft body 111 to appear and retreat smoothly and for retaining a steering member; an appearance/retreat mechanism 120 having a screw shaft body 121 extending in the axial direction and a screwing body 122 thread-engaging and for making the first shaft body 111 appear and retreat from/into the second shaft body 112; drive means 130 driving rotation of the screwing body 122; and two shock absorbing mechanisms 140 connecting the retaining mechanism 110 with the appearance/retreat mechanism 120 and absorbing a shock of secondary collision. The shock absorbing mechanisms 140 are disposed, sandwiching the screw shaft body 121 therebetween to make an equal distance from the screw shaft body 121 in the radial direction of the screw shaft body 121.SELECTED DRAWING: Figure 3
【課題】スムーズに操舵部材を出退させる。【解決手段】第一軸体111、および第一軸体111を出退可能に保持する第二軸体112を備え、操舵部材を保持する保持機構110と、軸方向に延在するねじ軸体121、および螺合する螺合体122を備え、第二軸体112に対し第一軸体111を出退させる出退機構120と、螺合体122を回転駆動させる駆動手段130と、保持機構110と出退機構120とを連結し、二次衝突の衝撃を吸収する二つの衝撃吸収機構140と、を備え、衝撃吸収機構140は、ねじ軸体121の径方向において、ねじ軸体121と等距離になるようにねじ軸体121を挟んで配置される操舵装置100。【選択図】図3
