FIELD: physics.
SUBSTANCE: group of inventions includes a cartridge, a method for assembling a drive transmission device for a photosensitive drum, and an electrophotographic image forming device. The cartridge includes: a rotating element; a rotating element, perceiving the transmitted rotating force, which in its internal space includes a containing portion and on which the rotating force is transferred, designed to be transmitted to the rotating element; a rotating connecting element including a free end portion having a part of the receiving rotating force, configured to receive the rotating force from the engaging part of the primary node, a connecting part, which connects with the said element, perceiving the transmitted rotating force, and, at least, a part of which is placed in the above-mentioned part, so that the rotation axis of the mentioned connecting element had the ability to rotate about the rotation axis of the said elements perceiving the transmitted rotating force to enable the gear output of the mentioned part receiving the rotating force from the engaging part of the primary node in order to move the said cartridge in a predetermined direction, a through hole extending through the said connecting portion; a sales part, which is able to receive rotating force from the said connecting element and passing through the said through hole and supported by the said element, perceiving the transmitted rotating force in the opposite terminal parts in such a way as to prevent the output of the mentioned connecting element out of engagement with the said element, perceiving the transmitted rotating force along with providing the possibility of rotation of the mentioned connecting element relative to the mentioned shaft.
EFFECT: providing a drive transmission structure for a cartridge that can be extracted to the outside of the main assembly of the device without a mechanism for moving the engagement portion of the main assembly side in the direction of its own rotation axis after moving in a predetermined direction substantially perpendicular to the rotation axis of the rotating element, such as an electrophotographic photosensitive drum, in which the disengagement of the connecting element is prevented without limitation of the inclination angle of the connecting element through the inside edges of the open part provided in the flanges, securing the cartridge using the structure of the drive transmission.
