PROBLEM TO BE SOLVED: To achieve further reduction of a number of components in a vehicular steering device provided with a telescopic mechanism.SOLUTION: A vehicular steering device includes a column housing (3) supported by a vehicle body, a column tube (1) which is supported so as to be movable in an axial direction relative to the column housing and which retains therein a steering shaft (2), and a telescopic mechanism (TL) that drives the column tube in the axial direction relative to the column housing. The telescopic mechanism includes an electric motor supported by the column housing, a screw shaft (5) connected to an output shaft of the electric motor, a nut member (6) engaged with the screw shaft, and a holder member (7) which is held by the nut member and which holds the column housing and the column tube with the nut member. The nut member moves in the axial direction of the screw shaft together with the holder member and the column tube in accordance with a rotational drive to the screw shaft.SELECTED DRAWING: Figure 2

    【課題】テレスコピック機構を備えた車両のステアリング装置において、部品点数の一層の削減を可能とする。【解決手段】車体に支持されるコラムハウジング(3)と、コラムハウジングに対し軸方向移動可能に支持されステアリングシャフト(2)を収容するコラムチューブ(1)と、コラムチューブをコラムハウジングに対し軸方向に駆動するテレスコピック機構(TL)を備える。テレスコピック機構は、コラムハウジングに支持される電動モータと、その出力軸に連結される螺子軸(5)と、これに螺合されるナット部材(6)と、これに保持されナット部材と共にコラムハウジング及びコラムチューブを挟持する保持部材(7)とを備え、螺子軸の回転駆動に応じて、ナット部材が保持部材及びコラムチューブと共に螺子軸の軸方向に移動する。【選択図】図2
