To provide a rotation transmission device which can prevent the rotary reaction force from suddenly becoming large in the rotational limit of a shaft.SOLUTION: A rotation transmission device comprises: a shaft 4; an outer ring 21 which has an inner periphery arranged in the periphery of the shaft 4; an engagement element 24 which is arranged between the shaft 4 and the inner periphery of the outer ring 21; a holder 25 which is arranged so as to be movable in the peripheral direction between the engagement position where the engagement element 24 is held and the engagement element 24 is engaged to the shaft 4 and the inner periphery of the outer ring 21 and the release position where the engagement is released; a centering spring 26 which is locked so as not to rotate to the shaft 4 and the holder 25 such that the holder 25 is elastically held at the release position and is rotated integrally with the shaft 4; an electromagnetic brake 27 which can brake the holder 25; and resistance generating means 52 which increases the rotation resistance as the rotation amount becomes larger when rotating the shaft 4 around the shaft in the left-right direction from the neutral state.SELECTED DRAWING: Figure 1

    【課題】軸の回転限界において急激に回転反力が大きくなるのを防止することができる回転伝達装置を提供する。【解決手段】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ばね26と、保持器25を制動することが可能な電磁ブレーキ27と、軸4をその中立状態から左右方向に軸周りに回転した際に、その回転量が大きくなるほど回転抵抗を増加させる抵抗発生手段52と、を有する構成とする。【選択図】図1
