To provide a steer-by-wire type steering device that is configured so that a turning actuator changes a direction of a turning part in accordance with an operation amount of a steering wheel that is sensed by a steering sensor, and when the direction of the turning part reaches a stroke end, a driver can surely sense the situation where the direction reaches the end through the steering wheel, and can perform steering lock even in a state where there is no power source supply.SOLUTION: The steer-by-wire type steering device comprises: a shaft connected to a steering wheel so as to rotate integrally with the steering wheel; an outer ring having an inner periphery arranged around the shaft; an engagement element arranged between the shaft and the inner periphery of the outer ring; a retainer arranged to be movable in a circumferential direction between an engagement position where the retainer engages the engagement element with the shaft and the inner periphery of the outer ring while retaining the engagement element and a releasing position where the retainer releases the engagement; a centering spring that elastically retains the retainer at the releasing position and is fixed to the shaft and the retainer not to turn so as to rotate integrally with the shaft; and a non-excitation actuating type electromagnetic brake that brakes the retainer.SELECTED DRAWING: Figure 1

    【課題】操舵センサで検知されるステアリングホイールの操作量に応じて転舵アクチュエータが転舵部の向きを変化させ、転舵部の向きがストロークエンドに到達したときに、運転者がステアリングホイールを通じてその状況を確実に感知することができ、電源供給がない状態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と一体に回転するように当該ステアリングホイールに連結された軸と、軸の周囲に配置された内周を有する外輪と、軸と外輪の内周間に配置された係合子と、係合子を保持して軸と外輪の内周に係合子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と、保持器を解放位置に弾性的に保持しかつ軸と一体に回転するように軸及び保持器に回り止めされたセンタリングばねと、保持器を制動する無励磁作動形電磁ブレーキと、を備える。【選択図】図1
