ABSTRACT A mechanism for supporting and extending a high lift device for aircraft wings A mechanism for supporting and extending a high lift device relative to an aerofoil, comprises one or more support beams (10) connected to the aerofoil, a pair of spaced apart chordwise extending wing ribs (20) bounding the support beam, a set of cylindrical rollers (23) mounted between the wing ribs for supporting the support beam (10) with their rotational axes aligned transversely with respect to the support beam (10), thesupport beam (10) including a gear rack (12) with gear teeth facing downwardly and a pinion gear (13) lying in meshing engagement with the gear rack (12), and an actuator (14) in driving engagement with the pinion gear (13) to extend and retract the high lift device (2-6) relative to the aerofoil (1). Bearings (45, 47) are provided for rotatably supporting the pinion gear (13) between the wing ribs (20) about a generally transverse axis of rotation, and there are splined engaging means (42, 43) between the actuator (14) and the pinion gear (13).
