To dispose a drive transmission system so that increase of the total size of a driving device can be suppressed.SOLUTION: A driving device includes a first motor, a first drive transmission system for transmitting rotation of the first motor by gears of multiple stages, a second motor, a second drive transmission system for transmitting rotation of the second motor by gears of multiple stages, and an output gear driven by both of the gear of the final stage of the first drive transmission system, and the gear of the final stage of the second drive transmission system. When a straight line passing through a shaft center of the output gear and a shaft center of the gear of the final stage of the first drive transmission system is a first straight line, and a straight line passing through the shaft center of the output gear and the shaft center of the gear of the final stage of the second drive transmission system is a second straight line, all of the shaft center of the first motor, the shaft center of the second motor, shaft centers of the gears of multiple stages of the first drive transmission system, and the shaft centers of the gears of the multiple stages of the second drive transmission system are kept in a region held by the first straight line and the second straight line.SELECTED DRAWING: Figure 4 【課題】駆動装置の全体的なサイズの大型化を抑制できるように、駆動伝達系を設けること。【解決手段】第１のモータと、第１のモータの回転を複数段のギヤによって伝達する第１の駆動伝達系と、第２のモータと、第２のモータの回転を複数段のギヤによって伝達する第２の駆動伝達系と、第１の駆動伝達系の最終段のギヤと、第２の駆動伝達系の最終段のギヤとの双方によって駆動される出力ギヤと、を備え、出力ギヤの軸中心と、第１の駆動伝達系の最終段のギヤの軸中心とを通る直線を第１の直線とし、出力ギヤの軸中心と、第２の駆動伝達系の最終段のギヤの軸中心とを通る直線を第２の直線とした場合において、第１の直線と第２の直線とに挟まれた領域内に、第１のモータの軸中心、第２のモータの軸中心、第１の駆動伝達系の複数段のギヤの各々の軸中心、および第２の駆動伝達系の複数段のギヤの各々の軸中心が、全て収まっている。【選択図】図４
