PROBLEM TO BE SOLVED: To prevent occurrence of damage due to shock load and increasing of rotational speed fluctuation by integrally connecting a driving transmission means to a shaft. SOLUTION: A driving transmission device has a gear (driving transmission means) 1 which transmits driving force by rotation, a shaft 2 which is rotatably supported while supporting the gear 1, and a parallel pin (rotation interlocking means) 3 which interlocks the rotation of the gear 1 and the shaft 1. A male screw (pressurizing means) 4 is arranged on the gear 1, at its position which is not agreed with a radial rotational center and offset byεtherefrom, for pressurizing the shaft 2. Since the shaft 2 is rotated in respect to the gear 1 upon receiving the pressurizing force of the male screw 4 for eliminating margin among the parallel pin 3, gear 1 and shaft 2, the gear 1 is integrally connected to the shaft 2 by means of the parallel pin 3. Fluctuation is not generated between their relative positional angles. It is thus possible to prevent damage due to shock load and increasing of rotational speed fluctuation.
