A server chassis includes a first tray, a second tray, a position latch and a position cam. The second tray and the first tray are pivoted with each other. The position latch is fixed on the first tray and moved accompany with the first tray. A protrusion and a first engaging structure are formed at an edge of the position latch. The position cam is pivoted on the second tray. An actuating nose and a second engaging structure are formed at an edge of the position cam. The actuating nose is located in a moving interval of the protrusion. The second engaging structure and the first engaging structure are contour matched with each other. Thereby, the position cam can be rotated to self-lock or self-unlock the position latch.
