PROBLEM TO BE SOLVED: To provide a vehicular steering device whose structure becomes simple, whose shaft direction length becomes short, which becomes cheap and which can generate friction torque.SOLUTION: In a vehicular steering device, a rotation limit mechanism 20 has: an annular groove 33 formed on one of a rotatable element 30 and an unrotatable element 40; an engaging member 21 arranged on the other so as to slide with the annular groove 33; a stopper member 64 capable of coming into contact with the engaging member 21; a driving device for moving the stopper member; and a mechanism for driving the driving device and moving the stopper member to the position to fit in the annular groove 33. At least one part of the engaging member 21 is a friction part for coming into contact with the annular groove 33, and by pressing the friction part to the annular groove 33 by a pressing device, the friction torque is generated at the time of relative rotation between one of the rotatable element 30 and the unrotatable element 40 and the engaging member 21.SELECTED DRAWING: Figure 2
【課題】構造が簡単になるとともに、軸方向長さが短くなり、安価となり、摩擦トルクを発生させることができる車両用操舵装置を提供する。【解決手段】回転制限機構20は、回転可能要素30および回転不能要素40の一方に形成された環状溝33と、他方に環状溝33に摺動可能に配置された係合部材21と、係合部材21に接触可能なストッパ部材64と、ストッパ部材を移動させる駆動装置と、駆動装置を駆動してストッパ部材を環状溝33に係入する位置へ移動させる機構を有し、係合部材21の少なくとも一部が、環状溝33と接する摩擦部であり、押圧装置で摩擦部を環状溝33に押圧することによって、回転可能要素30および回転不能要素40の一方と係合部材21との相対回転時に摩擦トルクを発生させるようにした車両用操舵装置。【選択図】図2
