Abstract:
1. A powered device for a vehicle sliding member, comprising: a base member adapted to be fixed to a vehicle body; a shaft rotatably supported on the base member; a drive source; a speed reduction mechanism configured to reduce an output speed of the drive source; an output drum rotatably supported on the base member through the shaft, the output drum being adapted to be connected to the vehicle sliding member; a clutch mechanism switchable between an engaged state in which the clutch mechanism transmits a driving torque, which is inputted from the drive source via the speed reduction mechanism, to the output drum, and a disengaged state in which the clutch mechanism prevents the driving torque from being transmitted to the output drum, the clutch mechanism being accommodated inside the output drum, wherein the clutch mechanism comprises: a first stop that limits displacement of the field core relative to the rotor in an axial direction of the rotor so that the field core is prevented from moving away from the output drum in the axial direction of the rotor, and wherein the first stop is disposed on the rotor and contacted with a radially inner periphery of an axial end surface of the field core.
