Abstract
A rotorcraft rotor having each of its blades fitted with a lead/lag damper. A connection device between the blade root of a blade under consideration and a lead/lag damper comprises a rod passing through a laminated ball joint secured to a distal endpiece of the lead/lag damper. The rod extends in the general plane in which the blade extends, being prevented from moving firstly in rotation by being embedded in the blade root and secondly in translation along the general transversely-extending direction of the blade by being pinned to a U-shaped yoke fastened to the blade root.
