Abstract: An electronic device chassis includes a casing and two limitation mechanisms. The casing includes two accommodating zones. The two limitation mechanisms are rotatably disposed at the casing. Each of the limitation mechanisms includes a first engaging portion near one of the accommodating zones, and a linkage structure near the other one of the accommodating zones, so that when the limitation mechanism is rotated, the first engaging portion and the linkage structure enter or leave the two accommodating zones, respectively. When two electronic assemblies are disposed in the two accommodating zones, two second engaging portions of the two electronic assemblies are located in rotating paths of the two first engaging portions, and a portion of each of the limitation mechanisms is located in a moving path of the corresponding electronic assembly. An electronic device is further provided.
