PROBLEM TO BE SOLVED: To favorably perform the fitment of a drive transmission rotating body and at least a drive source side rotating body or a drive object side rotating body while suppressing the displacement of an axial core and an axial deflection angle.SOLUTION: A drive transmission device comprises a guide member which contacts with an end face of an inner gear of an intermediate gear 107, an end face of an output gear formed of a plurality of outer teeth 106a which extend to an axial direction on an output shaft of a drive source side joint gear 106, or an end face of an input gear formed of a plurality of outer teeth 108a which extend to the axial direction on an input shaft of a drive object side joint gear 108, guides the end face of the output gear or the end face of the input gear to a clearance between mutually-opposing teeth of a gear of the intermediate gear at the contact face, or guides the end face of the intermediate gear to a clearance between mutually-opposing teeth of a gear of the output gear or the input gear. The guide member is arranged in the axial direction at a prescribed distance toward an end face side of the gear of the intermediate gear, an end face side of the output gear, or an end face side of a gear of an end face side mating side of the input gear. |
