CARTRIDGE ATTACHABLE TO AND DETACHABLE FROM ELECTROPHOTOGRAPHIC IMAGE FORMING APPARATUS MAIN BODY METHOD FOR ASSEMBLING PHOTOSENSITIVE DRUM DRIVE TRANSMISSION DEVICE AND ELECTROPHOTOGRAPHIC IMAGE FORMING APPARATUS

摘要

In a configuration which comprises a sphere in which a coupling member is an inclination (tilt) center and which includes an opening portion whereof a rotational force transmission target member has a diameter smaller than the diameter of the sphere in order to prevent the coupling member from becoming detached from the rotational force transmission target member as a result of an inner edge abutting the sphere an inner edge of the opening portion may limit the inclinable (tiltable) degree of the coupling member. While a pin (88) that is a shaft portion is inserted into a hole (86b) that is a through hole formed in a coupling member (86) both ends of the pin (88) are supported by a drive side flange (87) that is a rotational force transmission target member. In this manner the coupling member (86) the drive side flange (87) and the pin (88) are connected to each other and the coupling member (86) is prevented from becoming detached from the drive side flange (87) without having to limit the inclinable (tiltable) degree as the pin (88) adjoins an inner side of the hole (86b).
