The present invention relates to a shock absorbing device of an electronic power distribution device. The present invention minimizes transmission of an impact to an actuator (57) since the generated impact is absorbed and buffered by an impact buffering spring (60) installed between a control shaft (56) and a gear device (59) when a 2WD mode is switched into a 4WD mode or the 4WD mode is switched into the 2WD mode. 본 발명은 전자식 구동력분배장치의 충격완화 장치에 관한 것으로, 2WD 모드에서 4WD 모드로 절환시나 또는 4WD 모드에서 2WD 모드로 절환시에 발생된 충격이 컨트롤샤프트(56)와 기거기구(59)사이에 설치된 완충스프링(60)에 의해 흡수 및 완화됨으로써 액추에이터(57)쪽으로의 충격전달을 최소화시킬 수 있도록 된 것이다.
