To provide a clutch device which enables easy assembly.SOLUTION: A ball cam 2 has a driving cam 40 which rotates relative to a housing 12 when torque output from a speed reducer 30 is input thereto and a driven cam 50 which moves in an axial direction relative to the housing 12 when the driving cam 40 rotates relative to the housing 12. A clutch 70 is provided between an input shaft 61 and an output shaft 62 provided in such a way so as to be rotatable relative to the housing 12, allows transmission of torque between the input shaft 61 and the output shaft 62 in an engagement state where components of the clutch 70 engage with each other, and blocks the transmission of the torque between the input shaft 61 and the output shaft 62 in a non-engagement state where the components of the clutch 70 do not engage. A return spring 55 can bias the ball cam 2 to the opposite side of the clutch 70 with respect to the housing 12.SELECTED DRAWING: Figure 1 【課題】組み付けが容易なクラッチ装置を提供する。【解決手段】ボールカム２は、減速機３０から出力されたトルクが入力されるとハウジング１２に対し相対回転する駆動カム４０、および、駆動カム４０がハウジング１２に対し相対回転するとハウジング１２に対し軸方向に相対移動する従動カム５０を有する。クラッチ７０は、ハウジング１２に対し相対回転可能に設けられた入力軸６１と出力軸６２との間に設けられ、係合している係合状態のとき、入力軸６１と出力軸６２との間のトルクの伝達を許容し、係合していない非係合状態のとき、入力軸６１と出力軸６２との間のトルクの伝達を遮断する。リターンスプリング５５は、ボールカム２をハウジング１２に対しクラッチ７０とは反対側へ付勢可能である。【選択図】図１
