The invention relates to a flap actuator, comprising a flap, an actuating drive for actuating the flap along an actuating path from a closed position to an open position, and a linkage mechanism, the linkage mechanism comprising a toggle joint having a first leg and a second leg. The first leg is rotatably supported at a first rotation point and the second leg is rotatably supported via a second rotation point. Furthermore, the first leg and the second leg are rotatably linked to each other at a moveable third rotation point, wherein the second leg includes a guiding slot along a longitudinal direction of the second leg and the first leg includes a guiding projection engaging the guiding slot, wherein the guiding projection forms the third rotation point and is supported in the guiding slot to be moveable along the longitudinal direction. The toggle joint comprises an elastic element which, when the flap is in its closed position, exerts a force on the toggle joint so that the toggle joint causes a restoring force on the flap in the closing direction, and/or the guiding slot has a length L and a width B, wherein L>B, and the second leg, at a position Pos2 along the longitudinal direction of the guiding slot at which the guiding projection is situated when the flap is in its closed position, includes a second recess having a width Br2, wherein Br2>Br, and wherein the guiding projection, when the flap is in its closed position, is in at least partial engagement with the second recess so that the toggle joint causes a retaining force and/or a restoring force on the flap in the closing direction.
