ABSTRACT:
A reduction gear mechanism comprising a worm and a worm wheel which mechanism includes a magnet clutch wherein a coil is disposed in one side of the worm wheel which serves as a rotor, while an armature is disposed in the other side of the same. Upon energization of the coil, the mechanism acts as a normal reduction gear whereas, upon deenergization, an output power shaft of the clutch can be rotated freely or independently. Since the incorporation of the magnet clutch results in no substantial increase of the size of the reduction gear mechanism, the mechanism can be advantageously installed where a space for installation is restricted, such as a door of an automobile.
