摘要

The device (1) has a toothed wheel (40) engaged with a worm (60) arranged in a housing (10) of a winch (2). The wheel is rotated along rotation directions (RX1, RX2) with respect to the housing around a first rotation axis (X). The worm is provided with a flange (70) housed in a groove of the housing and forming an axial abutment along a second rotation axis (Y). The flange is arranged opposite to a stop-spring (80) along the worm with respect to a plane (Pxz) containing the first rotation axis and a third rotation axis (Z) perpendicular to the first and second rotation axes.
