Abstract
There is provided a range switching device that can switch the shift ranges by use of a mechanical driving force source even when the motor does not normally function. The range switching device includes an output axle coupled with the shift shaft of an automatic transmission, a motor, an elastic driving device whose driving force source is elastic energy of an elastic member, and a coupling mechanism that couples the output axle, the motor, and the elastic driving device with one another; the elastic driving device has a holding mechanism in which there can be performed switching between a holding state where accumulated elastic energy is held and a releasing state where the elastic energy is released so as to drive the output axle.
