  • Publication number: 20210095724
    Abstract: A rotation braking device includes a clutch mechanism disposed between an inner member and an outer member. The clutch mechanism includes an electromagnetic actuator which controls relative rotation of the cage such that, due to the relative rotation, engaging elements are moved between an engaged position and a neutral position. An armature is rotationally fixed relative to the cage, and can be directly magnetically attracted to an electromagnet which is rotationally fixed relative a housing that houses the clutch mechanism. The outer member is directly supported in a radial direction by the housing and engages the housing so as to limit relative rotation relative to each other.
