least one of the two half cowls of the thrust reverser during the maneuver for closing the half cowls the locking unlocking means of the stress absorbing device are put into action at the end of the closing of the half cowls in order to end this closing maneuver and to finally lock the half cowls in the closed position by locking the rod 61 in its retracted position the operation of this stress absorbing device 6 is described hereafter with reference to fig6 a to 6 g which illustrate successive configurations of the stress absorbing device 6 fig6 a illustrates the stress absorbing device 6 in a locking configuration when the half cowls are in the closed position when the rod 61 is in a retracted position with the fingers of the part forming a hook 63 which hook up the protrusion of the second end 612 of the rod 61 thereby blocking the rod 61 in the extend direction towards the left in the figure the external abutment 614 bearing against the first end 621 of the body 62 thereby blocking the rod 61 in the retract direction towards the right in the figure fig6 b illustrates the beginning of the maneuver for unlocking the stress absorbing device 6 concomitantly at the beginning of the maneuver for opening one or both half cowls where the slider 64 begins to move towards the first end 621 of the body 62 as schematized by the arrow cs leading to the displacement of the fingers of the part forming a hook 63 towards the step or recess.
