Abstract:
1. A power switching device for vehicle, the power switching device comprising: an engaging mechanism for connecting and disconnecting a pair of rotating members arranged on a driving force transmission passage from a driving source to wheels; an operating mechanism for switch-operating the engaging mechanism between an engaged condition and a disengaged condition; an electric actuator for providing operating power to the operating mechanism; and a waiting mechanism having an elastic member for temporarily accumulating the operating power and then transmitting the operating power to the engaging mechanism; wherein the engaging mechanism has a pair of engage portions, each of the pair of rotating members having a respective one of the engage portions, the engaging mechanism being switchable between the engaged condition and the disengaged condition by moving one of the engage portions relative to the other engage portion in an axial direction of the rotating member; wherein the elastic member is incorporated into the waiting mechanism so that the elastic member can temporarily accumulate the operating power only when the engaging mechanism is switched from the disengaged condition to the engaged condition; and wherein the pair of rotating members are a differential case of a differential device and one of right and left axles.
