Abstract
An electric driving device for a transmission can be reduced in size with a simple structure, and can be installed in a small-sized car, such as a passenger car. In this electric driving device, a shift shaft effects a selecting operation by its displacement in the axial direction and a shifting operation by its rotation. The displacement of the shift shaft in the axial direction is effected by rocking and displacing a rocking arm by means of a first actuator or . Rotation of the shift shaft is effected by pushing and/or pulling a rocking arm by means of a second actuator . This driving arm is fixedly disposed on the outer peripheral surface of a spline tube which is brought into spline-engagement with the shift shaft
