Abstract: An adjustment device for an automotive wing mirror includes an adapter fixed to the wing mirror and having a virtual rotation center and first and second virtual axes perpendicularly intersecting with each other relative to the virtual rotation center, and an adapter driving module to drive the adapter. The adapter driving module includes a bowl-shaped lower shell, an upper shell covering on the lower shell, and two actuator mechanisms. Each actuator mechanism includes a driving motor, a reduction gear set, a clutch assembly meshing with the reduction gear set, and a ring gear meshing with the clutch assembly. The ring gears partially extend through the upper shell and are connected to the adapter on the first virtual axis and the second virtual axis. The adapter is operable of revolving relative to the virtual rotation center in two intersecting directions.

Abstract: A clutch assembly is connected between a gear set connected to a driving motor of an actuator mechanism of a wing mirror and a ring gear connected to an adapter, and includes a clutch gear meshing with an extremity of the gear set, a pinion gear, and left-handed and right-handed clutch springs. The clutch gear defines a groove in an inner circumference. The pinion gear includes a gear portion meshing with the ring gear, and a clutch holding surface integrally formed with the gear portion. The left-handed and right-handed clutch springs are fitted about the clutch holding surface and are coiled on the clutch holding surface in two opposite directions. Each of the left-handed and right-handed clutch springs includes a protrusion engaged in the groove.
