Electric flight control mechanism of a rotorcraft capable of causing a variation in the pitch of the blades of at least one rotor of the rotorcraft, the mechanism comprising: -) a joystick articulated on a support with multidirectional tilting (B1, B2) about a centre of mobility of the joystick on the support, the joystick comprising an axially extended rod provided at its proximal end with means for accommodating a hand grip and provided at its opposite distal end with means for movable mounting on the support, said joystick being movably mounted on the support with multidirectional tilting by anchoring the rod provided at its distal end in an anchoring zone in the support, with a tilting drive motion of the joystick causing overall deflection of the rod from its anchoring zone to its proximal end; -) means for detecting the tilting position of the joystick, said detection means generating, depending on the tilting position of the joystick, electrical signals used by computation means generating control orders for implementing at least one actuator capable of causing a pivoting manoeuvre of said blades about a pitch axis in order to vary their pitch; -) at least one stop component (18, 18', 23) for limiting the bending stroke of the rod, said at least one stop component (18, 18', 23) being provided at a transverse distance about the rod, said at least one stop component (18, 18', 23) defining about the rod, from said anchoring zone, a wrap-around surface that is flared towards the proximal end of the rod, said wrap-around surface delimiting an authorized bending stroke of the rod, said mechanism comprising force-sensing means providing, by generating resistant forces that counteract the tilting drive forces of the joystick by the person, the person with a feeling of said resistant forces by means of the joystick, the force-sensing means comprising the intrinsic resistance of the rod to deform by bending, said resistant forces being developed by the rod opposing its bending deformation, and said at least one stop component (18, 18', 23) being movably mounted on the support using means for adjusting the relative position between the stop component (18, 18', 23) and the rod, said adjustment means forming means for adjusting the intensity of the resistant forces developed by the rod. -) a joystick articulated on a support with multidirectional tilting (B1, B2) about a centre of mobility of the joystick on the support, the joystick comprising an axially extended rod provided at its proximal end with means for accommodating a hand grip and provided at its opposite distal end with means for movable mounting on the support, said joystick being movably mounted on the support with multidirectional tilting by anchoring the rod provided at its distal end in an anchoring zone in the support, with a tilting drive motion of the joystick causing overall deflection of the rod from its anchoring zone to its proximal end; -) means for detecting the tilting position of the joystick, said detection means generating, depending on the tilting position of the joystick, electrical signals used by computation means generating control orders for implementing at least one actuator capable of causing a pivoting manoeuvre of said blades about a pitch axis in order to vary their pitch; -) at least one stop component (18, 18', 23) for limiting the bending stroke of the rod, said at least one stop component (18, 18', 23) being provided at a transverse distance about the rod, said at least one stop component (18, 18', 23) defining about the rod, from said anchoring zone, a wrap-around surface that is flared towards the proximal end of the rod, said wrap-around surface delimiting an authorized bending stroke of the rod, said mechanism comprising force-sensing means providing, by generating resistant forces that counteract the tilting drive forces of the joystick by the person, the person with a feeling of said resistant forces by means of the joystick, the force-sensing means comprising the intrinsic resistance of the rod to deform by bending, said resistant forces being developed by the rod opposing its bending deformation, and said at least one stop component (18, 18', 23) being movably mounted on the support using means for adjusting the relative position between the stop component (18, 18', 23) and the rod, said adjustment means forming means for adjusting the intensity of the resistant forces developed by the rod.
