Summary:To provide a clutch device capable of maintaining, with a simple configuration, the state of a clutch.SOLUTION: A motor 20 comprises: a stator 21 which is fixed to a housing 12; and a rotor 23 which is provided so as to be rotatable relative to the stator 21. When supplied with electric power, the motor 20 can output torque. A reduction gear 30 can output the torque of the motor 20 after reducing it. A ball cam 2 has: a driving cam 40 which is rotated relative to the housing 12 by the torque from the reduction gear 30; and a driven cam 50 which moves relative to the housing 12 in the axial direction. A clutch 70 permits torque transmission when in an engaged state where it is engaged, and blocks torque transmission when in a disengaged state where it is not engaged. When applied with force in the axial direction from the driven cam 50, a state changing part 80 can change the state of the clutch 70. Cogging torque generated between the rotor 23 and the stator 21 is set to be such a degree that the rotor 23 can rest at an arbitrary rotational position with respect to the stator 21.SELECTED DRAWING: Figure 1 【課題】簡単な構成でクラッチの状態を維持可能なクラッチ装置を提供する。【解決手段】モータ２０は、ハウジング１２に固定されたステータ２１、ステータ２１に対し相対回転可能に設けられたロータ２３を有し、電力の供給によりトルクを出力可能である。減速機３０は、モータ２０のトルクを減速して出力可能である。ボールカム２は、減速機３０からのトルクによりハウジング１２に対し相対回転する駆動カム４０、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、係合している係合状態のとき、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、トルクの伝達を遮断する。状態変更部８０は、従動カム５０から軸方向の力を受け、クラッチ７０の状態を変更可能である。ロータ２３とステータ２１との間に生じるコギングトルクは、ロータ２３がステータ２１に対し任意の回転位置で静止可能な程度の大きさに設定されている。【選択図】図１
