To provide a link member for connecting a pylon strut and a wing, which link member is easily tightened and removed even when there is a narrow space therearound. A link member 50 includes a link plate 51 functioning as a load transfer element, a coaxial bush 52 provided at one end of the link plate 51, and an eccentric bush 53 provided at the other end of the link plate 51. A set of the link plates consisting of two link plates 51 are arranged opposite to and away from each other with a prescribed distance, and bolts B1 and nuts N1 are used to connect the connecting piece 12 to the wing mount 13. The link member 50 further includes nut retainers 60 provided on the inner side of the link member 50 to restrict rotation of the respective nuts N1.

A link member for connecting an aircraft pylon to a wing of an aircraft, the link member comprising: a first load transfer member including a first load transfer section, and further including a 1A connecting section and a 1B connecting section respectively provided at both ends of the first load
1. A link member for connecting an aircraft pylon to a wing of an aircraft, the link member comprising: a first load transfer member including a first load transfer section, and further including a 1A connecting section and a 1B connecting section respectively provided at both ends of the first load transfer section;a second load transfer member including a second load transfer section, and further including a 2A connecting section and a 2B connecting section respectively provided at both ends of the second load transfer section, the second load transfer member being arranged opposite to and spaced a distance apart from the first load transfer member;a first fastener including a bolt and a nut for fastening the pylon to the 1A and 2A connecting sections, the bolt extending through the 1A and 2A connecting sections;a second fastener including a bolt and a nut for fastening the wing to the 1B and 2B connecting sections, the bolt extending through the 1B and 2B connecting sections; anda rotation restricting member comprising a first portion that extends at least partially around the nut of at least one of the first and second fasteners for restricting rotation of the respective nut relative to the bolts of the first and second fasteners extending through the connecting sections,wherein the rotation restricting member is fixed by a third fastener to one of the first and second load transfer sections where the respective nut is located. 2. The link member according to claim 1, wherein an eccentric bush is provided at the 1B and 2B connecting sections,wherein the bolt of the second fastener is supported by the 1B and 2B connecting sections with the eccentric bush provided between the bolt of the second fastener and the 1B and 2B connecting sections, andwherein the rotation restricting member is provided as divided pieces comprising a first member and a second member which correspond to the first fastener and the second fastener, respectively. 3. The link member according to claim 1, comprising a fall-off preventing member for preventing the respective bolts of the first and second fasteners from falling off, wherein the fall-off preventing member is fixed to either one of the first and second load transfer sections where the head of the bolt is located. 4. The link member according to claim 3, wherein the fall-off preventing member comprises a single piece, andwherein the fall-off preventing member comprises a flange that contacts a portion of at least one of the first fastener and the second fastener to interfere with displacement of the fall-off preventing member relative to the respective bolts of the first and second fasteners. 5. The link member according to claim 1, wherein a front side when the link member is mounted to the pylon and the wing, and an inner side on the other side opposite to the front side across the link member exist, andwherein the respective bolts of the first and second fasteners are located on the front side, andwherein the respective nuts of the first and second fasteners are located on the inner side. 6. An aircraft pylon connected to a wing of an aircraft with a link member, wherein the link member is the link member according to claim 1. 7. The link member according to claim 1, wherein the rotation restricting member is fixed to an outside surface of either one of the first and second load transfer sections where the nut is located.
