A retractable step (1) for a vehicle (100) provided with an outer casing (2) is described; an extractable footboard (3) which is carried in a slidable manner by the outer casing (2) so as to slide between an extracted operating position and a retracted operating position; and an electrically operated motorised transmission (4) which is adapted to move the extractable footboard (3) between the extracted operating position and the retracted operating position; the motorised transmission (4) comprises: a connecting rod (18) connected to the retractable footboard (3), a crank (19) connected to the connecting rod (18), and actuator means (20) for driving the crank (19) in rotation; the crank (19) is provided with a rectilinear cam (19c) that extends along the intermediate portion of the crank (18); the actuator means comprise a cam-following pin (22) that cooperates in a sliding manner with the rectilinear cam (19c), and a motorised mechanism (24) which is configured to drive the cam-following pin (22) along a circular trajectory so as to drive the crank (19) in rotation.
