Abstract
The low portion (9) of a landing gear strut (3) carrying running means such as a wheel (8) is capable of swivelling together with the running means relative to the strut. A system of cranks (17) receives the necessary force for swivelling the wheel during retraction and extension of the landing gear from a rod (13) which is fixed to the aircraft structure (2) at a point different from the point at which the strut (3) is fixed. The rod (13) is of variable length (piston and cylinder arrangement 31), and the crank system has a stop (33) against excessive swivelling. The arrangement is such that swivelling is restricted to a selected portion of the landing gear's travel, e.g. to ensure that the wheel enters the aircraft body at a particular degree of swivel.
