  • Publication number: 20250181023
    Abstract: A cartridge unit detachable from a main body of an image forming device includes: a rotation member; a driven coupler arranged at one end portion of the rotation member in an axial direction of the rotation member; and a coil spring arranged to be expandable and compressible in the axial direction, a first end portion of the coil spring being fixed onto the driven coupler, and the coil spring being wound in a first direction from the first end portion toward a second end portion. When a rotational force is transmitted to the second end portion of the coil spring in the first direction or in a second direction opposite to the first direction, a portion of the transmitted rotational force is converted into a force that decreases or increases a diameter of the coil spring, and the first end portion of the coil spring presses the driven coupler in a direction perpendicular to the axial direction.
