To provide a rotation transmission device capable of achieving that when an orientation of a steering part of a steer-by-wire type steering device reaches a stroke end, a status is completely sensed by a driver through a steering wheel.SOLUTION: A rotation transmission device includes: a retainer 25 for retaining an engagement piece 24 arranged between a shaft 4 of a steering wheel 1 and an inner periphery of an outer ring 21, and arranged to be movable in a peripheral direction between an engagement position engaging with the shaft 4 and the inner periphery of the outer ring 21 and a releasing position releasing the engagement; a centering spring 26 locked to the shaft 4 and the retainer 25; an electromagnetic brake 27 for braking the retainer 25; and a brake case 28 for storing the outer ring 21 and the electromagnetic brake 27, wherein the brake case 28 and the outer ring 21 are connected to permit a relative rotation within a prescribed angular range and inhibit the relative rotation exceeding the range, and both of the brake case 28 and the outer ring 21 are energized by an elastic member 33 toward a central position of the range.SELECTED DRAWING: Figure 1

    【課題】ステアバイワイヤ式操舵装置の転舵部の向きがストロークエンドに到達したときにステアリングホイールを通じてその状況を確実に運転者に感知させることを実現可能な回転伝達装置を提供する。【解決手段】ステアリングホイール1の軸4と外輪21の内周間に配置された係合子24を保持して軸4と外輪21の内周に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移動可能に配置された保持器25と、軸4及び保持器25に回り止めされたセンタリングばね26と、保持器25を制動する電磁ブレーキ27と、外輪21と電磁ブレーキ27を収容するブレーキケース28とを備え、ブレーキケース28と外輪21は所定の角度範囲内での相対回転を許容し、当該範囲を超える相対回転を阻止するように連結され、弾性部材33で両者28,21を当該範囲の中央位置に向けて付勢する。【選択図】図1
