To provide a transmission which can minimize size increase of a physical constitution, and to provide an electric drive device including the transmission and an on-vehicle system including the electric drive device.SOLUTION: A speed reducer 50 comprises: an input shaft 70b; an output shaft 72b that extends in a direction in which the input shaft 70b extends; a speed reduction mechanism that reduces a rotational speed of the input shaft 70b and transmits the rotation to the output shaft 72b; a case 60 that accommodates the input shaft 70b, the output shaft 72b, and the speed reduction mechanism; and a brake mechanism that applies braking torque to the input shaft 70b. The brake mechanism is accommodated in the case 60.SELECTED DRAWING: Figure 4
