The force transmission element includes at least one threaded bolt having a bolt head, and a toothed rack engaged with the motor pinion gear. The toothed rack includes a toothed element having a base defining a first side having teeth attached thereto, and a second side opposite to the first side and forming a groove extending in a longitudinal direction of the toothed element for accommodating the bolt head. The groove defines a groove width corresponding to a width of the bolt head. The toothed rack further includes a support element connected with the sliding gate using the at least one bolt, and that is adapted to receive the toothed element. The support element includes at least one through bore for receiving the at least one bolt.
