<p>An electromagnetically controlled spring clutch mechanism including a rotating output member (2), a rotating input member (26), an armature assembly (6), an electromagnetic coil assembly (76) and a coil spring (8). The coil spring (8) is fitted astride both the output boss (14) of the rotating output member (2) and the input boss (30) of the rotating input member (26). One end (70) of the coil spring (8) is anchored at the rotating input member (26), and the other (72) is anchored at the armature assembly (6). The rotor of the rotating output member (26), the armature assembly (6), and the electromagnetic coil assembly (76) are arranged in this sequence in the axial direction. The electromagnetic coil of the electromagnetic coil assembly (76) is positioned radially outwardly of the coil spring (8). The electromagnetic coil assembly (76) includes a casing (92), which covers the rotor of the rotating output member (2), the armature assembly (6), the electromagnetic coil of the electromagnetic coil assembly (76) and the coil spring (8). <IMAGE> <IMAGE></p> |
