To provide a steer-by-wire type steering device which can perform steering lock even when an electrical failure occurs in an electromagnetic brake in a case where a direction of a steering part reaches a stroke end.SOLUTION: A steer-by-wire type steering device comprises: a shaft 4 which is coupled so as to integrally rotate with a steering wheel 1; an outer ring 21 which has an inner periphery arranged in a periphery of the shaft 4; an engagement element 24 which is arranged between the inner peripheries of the shaft 4 and the outer ring 21; a holder 25 which holds the engagement element 24 and is arranged so as to be movable in the peripheral direction between the engagement position where the engagement element 24 is engaged with the inner peripheries of the shaft 4 and the outer ring 21 and the release position where the engagement is released; a centering spring 26 which is rotationally locked to the shaft 4 and the holder 25 so as to elastically hold the holder 25 at the release position and integrally rotate with the shaft 4; an electromagnetic brake 27 which can brake the holder 25; and rotation restriction means 52 which mechanically restricts a rotation range of the shaft 4 to the outer ring 21 within a prescribed range.SELECTED DRAWING: Figure 1

    【課題】転舵部の向きがストロークエンドに到達したときに、電磁ブレーキに電気的失陥が生じたときでもステアリングロックを行うことができるステアバイワイヤ式操舵装置を提供する。【解決手段】ステアリングホイール1と一体に回転するように連結された軸4と、軸4の周囲に配置された内周を有する外輪21と、軸4と外輪21の内周間に配置された係合子24と、係合子24を保持して軸4と外輪21の内周に係合子24を係合させる係合位置と当該係合を解除する解放位置との間を周方向に移動可能に配置された保持器25と、保持器25を前記解放位置に弾性的に保持しかつ軸4と一体に回転するように軸4及び保持器25に回り止めされたセンタリング26ばねと、保持器25を制動することが可能な電磁ブレーキ27と、外輪21に対する軸4の回転範囲を所定の範囲内に機械的に制限する回転制限手段52と、を有する構成とする。【選択図】図1
