opening leaf it essentially comprises a handle support 14 which is fixed on an inside face 16 of the panel 12 and a lever 18 for grasping which is arranged on the outside face 20 of the panel 12 but which is articulated to the support 14 about an axis a 1 substantially parallel to a general plane of the panel 12 the direction of the axis a 1 will arbitrarily be termed vertical while the direction perpendicular to the axis a 1 and also parallel to the general plane of the panel 12 will be said to be longitudinal thus the lever 18 which runs longitudinally comprises at a longitudinal front end an articulation tab 22 which extends toward the inside of the panel 12 through an opening made therein and which is mounted so that it can pivot on the support 14 the lever 18 can therefore be brought from a position of rest illustrated in fig1 into an opening position not depicted in which its longitudinal rear end is moved away from the panel 12 transversely outward and in which the lever 18 actuates a transmission mechanism not depicted allowing for example a lock which holds the opening leaf in the closed position to be triggered to bring the lever 18 into its opening position the user of the vehicle has to insert his or her hand between the bodywork panel 12 and a surface 26 for grasping of the lever 18 so that this lever can be pulled toward him or her outward with respect to the panel 12 for this to be possible there is.
