  • Rotational force driving assembly process cartridge
    Patent number: 9740163
    Abstract: The present invention relates to a rotational force driving assembly and a process cartridge used for being engaged with a rotational force driving head inside an electrophotographic image forming device. The rotational force driving assembly can comprise a hub, a rotational force receiving component, a side plate, and an axis offset adjusting mechanism. When the axis offset adjusting mechanism is not subjected to external force, the axis offset adjusting mechanism enables the axis of the rotational force receiving component to be parallel and offset to the axis of the hub. When the axis offset adjusting mechanism is subjected to external force, the rotational force receiving component extends out to be engaged with the rotational force driving head.
