<P>PROBLEM TO BE SOLVED: To provide a driving transmission device and an image forming device provided with it capable of preventing transmission of vibration caused in meshing to a rotary body for forming image of a driven shaft, coping with a case where a mounting position in the axial direction of a gear is changed due to part dimensional tolerance, adjusting suppressing force in accordance with vibrating force generated at a meshing period, and improving quality of image and being suitable for miniaturization and reduction of weight. <P>SOLUTION: In this driving transmission device having a driving shaft 1 connected with a driving source like a motor, the driven shaft 3 for performing work, and a helical gear 4 as a transmission mechanism part for transmitting torque of the driving shaft 1 to the driven shaft 3, a damping rotary roller 5 turning together with rotation of a side face of the helical gear is pressed against the side face which is in the vicinity of a meshing part of the rotating driven side helical gear 4 and on which thrust force is applied. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
