A driving apparatus has a problem in that a tip end of an output shaft, which is inserted through a hollow space, is difficult to be fitted into the apparatus body during the maintenance. Therefore, a driving apparatus includes an input shaft with a hollow space formed therein that penetrates therethrough in the axial direction, a motor that rotates the input shaft, a reduction gear that receives the power of the motor from the input shaft, an output shaft inserted through the hollow space of the input shaft and adapted to rotate about the rotation axis with power output from the reduction gear, and a coupling connected to a tip end of the output shaft. A first bearing for supporting the output shaft is arranged, and a second bearing for supporting the output shaft is arranged in the hollow space between the input shaft and the output shaft.
