A retractable landing gear is arranged so as to provide, in use, a highly inclined shock absorber while avoiding high shearing stresses on the shock absorber. The landing gear includes a pivoting panel fixed to an aircraft structure to pivot about a raising axis; a shock absorber including a strut fixed to the pivoting panel so as to pivot relative thereto about a tilt axis, and a sliding rod mounted to slide in the strut and carrying a set of wheels at its bottom end; and a coupling member connected to the pivoting plate and to the bottom end of the sliding rod. Also included is a mechanism for raising and holding the landing gear.

Raisable landing gear comprising: a pivoting panel fitted with means for fixing to an aircraft structure so as to pivot about a raising axis which extends substantially in a direction parallel to a longitudinal direction of the aircraft; a shock absorber comprising a strut fixed to the pivoting panel so as to pivot relative thereto about a tilt axis which is substantially perpendicular to the forward travel direction of the aircraft structure, and a sliding rod mounted to slide inside the strut and carrying a set of wheels at its bottom end; coupling means having a first end hinged to the pivoting panel about an axis which is parallel to the tilt axis of the shock absorber but separate therefrom, and a second end hinged to the sliding rod in the vicinity of the set of wheels about an axis which is parallel to the tilt axis of the shock absorber; and shock absorber raising and holding means having a first end connected to the aircraft structure to pivot about a tilt axis parallel to the tilt axis of the shock abosrber strut and about an axis perpendicular to said tilt axis of the shock absorber strut and a second end connected via a hinged connection to the strut of the shock absorber.
