1. A thrust reverser for an aircraft propulsion unit, comprising:
a fixed portion;
a movable portion; and
at least one actuator, wherein
the actuator comprises a first member and a second member which cooperate with each other so as to be able to be displaced relative to each other between a first position and a second position defining a stroke of the actuator,
one of the first member and the second member is connected to the fixed portion of the thrust reverser by a first connecting element, wherein the first connecting element connects to a screw of the actuator,
the other of the first member and the second member is connected to the movable portion of the thrust reverser by a second connecting element,
the thrust reverser is configured such that a displacement of the first member and the second member relative to each other between the first position and the second position causes a translational displacement of the movable portion relative to the fixed portion respectively between a direct thrust position and a thrust reversal position, and
when the first member and the second member are displaced relative to each other in the first position, a distance between the first connecting element and the second connecting element is less than the stroke of the actuator.
