An extension table comprising two simultaneously displaceable table top sections, below which is stored an extension leaf having a length corresponding to the width of the table. The table top sections are by link mechanisms (26a, 26b, 26c) interconnected to a cam disc (24). The extension leaf is rotatable around a pivot (34) concentric to the cam disc. At the lower side of the extension leaf a driving stud is situated for engagement with the cam disc, which can be rotated via an operating unit. By the rotation the table top sections are pushed apart while simultaneously a turning of the extension leaf takes place. Below the extension leaf a bar parallelogram (70) is connected to the cam disc such that is ascends to elevating the extension leaf to level with the table top. The facing surface of the cam disc is provided with a wedge element for cooperating with another wedge element at the reverse of the extension leaf for wedging the extension leaf against the table top in its storage position. The cam disc can be rotated by e.g. cable (8), sprocket shaft, electric motor, such that only a single operating unit requires activation in order to extend the table by the extension leaf or return it to its storage position.
