To restrict rotation of an input at a predetermined position and deal with rapid input in an opposite direction in the restriction state.SOLUTION: A rotation transmission device includes an electromagnetic clutch unit 7 which includes an inner ring 20 and an outer ring 21 and an engagement element 24 assembled between an outer periphery of the inner ring 20 and an inner periphery of the outer ring 21 and switches between an engagement state where the inner ring 20 and the outer ring 21 are engaged through the engagement element 24 and an engagement release state where engagement between the inner ring 20 and the outer ring 21 is released. The inner ring 20 is connected to input side shafts 4, 16. The outer ring 21 is fixed and the inner ring 20 includes a cam ring 71 and an intermediate shaft 72 which are formed by components different from each other and supported so as to rotate relative to each other. When the cam ring 71 and the intermediate shaft 72 rotate relative to each other by a predetermined angle, the cam ring 71 and the intermediate shaft 72 integrally rotate.SELECTED DRAWING: Figure 1

    【課題】回転の入力に対して所定の位置でその回転を規制できるようにするとともに、その規制状態での急激な反対方向への入力に対しても対応できるようにする。【解決手段】内輪20及び外輪21と、内輪20の外周と外輪21の内周との間に組み込まれた係合子24を備え、係合子24を介して内輪20と外輪21とを係合させる係合状態と内輪20と外輪21との係合を解除する係合解除状態との間で切り替える電磁クラッチユニット7を備え、内輪20は入力側のシャフト4,16に連結され、外輪21は固定であり、内輪20は別体の部品で構成され互いに相対回転するように支持されたカムリング71及び中間軸72を備え、カムリング71と中間軸72が所定の角度だけ相対回転するとカムリング71と中間軸72は一体となって回転する回転伝達装置とした。【選択図】図1
