Claim:
1. A self-closing slide rail assembly, comprising: a first rail; a second rail longitudinally displaceable relative to the first rail, the second rail including a guide portion and a stop portion adjacent to the guide portion, the guide portion and the stop portion defining a first positioning groove therebetween; and a self-closing mechanism mounted on the first rail and including: wherein when the actuating portion of the self-closing mechanism is engaged in the first positioning groove of the second rail and the second rail is displaced relative to the first rail from a retracted position toward an extended position, the second projection of the movable member is moved from the first edge to the second edge and enters into engagement with the engaging portion, and the elastic member of the self-closing mechanism stores elastic energy; and when the second rail is displaced relative to the first rail from the extended position toward the retracted position, the guide portion of the second rail guides the actuating portion of the self-closing mechanism into engagement with the first positioning groove of the second rail such that the second projection of the movable member displaces from the engaging portion and, as the elastic member of the self-closing mechanism releases the elastic energy, is moved from the second edge to the first edge, the movable member thereby automatically driving the second rail back to the retracted position.
