Abstract
A drive transmission device in one embodiment of the disclosure includes a pair of output shafts, a differential, a clutch (power transmission unit), and a control unit. The pair of output shafts connected to a pair of speed reducers that are disposed to face each other. The differential receives a driving force from a drive source and outputs the driving force to the pair of output shafts; The clutch acts on the differential and takes a first state in which a load imbalance between the pair of output shafts is adjusted or a second state in which the pair of output shafts are rotated directly by the driving force. The control unit switches the state of the clutch based on difference information regarding a difference in rotation between the pair of speed reducers.
