Zusammenfassung:To provide a clutch device which has the same functions as a conventional clutch device and enables installation to a small space and weight saving.SOLUTION: A clutch device 1 includes: a roller type one-way clutch 3 which includes an outer ring 7, an inner ring 9 which is disposed coaxially with the outer ring 7 at the radial inner side of the outer ring 7 so as to be rotatable relative to the outer ring 7, and multiple rollers 21 disposed between the outer ring 7 and the inner ring 9 and enables rotation of the inner ring 9 only in one direction; and a cam type clutch 5 which is disposed adjacent to the roller type one-way clutch 3 in an axial direction at the inner diameter side of the outer ring 7. The cam type clutch 5 includes: a switch plate 45 which is rotatably provided at the outer ring 7 so as not to be movable in an axial direction; and an operation plate 43 which moves in the axial direction relative to the switch plate 45 through a cam mechanism to engage with the inner ring 9.SELECTED DRAWING: Figure 1 【課題】機能は従来と同じで、省スペースへの設置を可能とし、軽量化も可能とするクラッチ装置を提供すること。【解決手段】 クラッチ装置1は、外輪7と、外輪7の径方向内方に外輪7と同軸に且つ相対回転可能に配置された内輪9と、外輪7と内輪9との間に介装された複数のローラ21とを備え、内輪9の一方向への回転のみを可能とするローラ型ワンウェイクラッチ3と、外輪7の内径側でローラ型ワンウェイクラッチ3の軸方向に隣接して配置されたカム型クラッチ5とを有し、カム型クラッチ5は、外輪7に軸方向移動不能に且つ回転可能に設けられた切り替えプレート45と、カム機構を介して切り替えプレート45に対して軸方向に移動することにより内輪9と係合する作動プレート43とを備えている。【選択図】図1
