Abstract
An actuator unit for a braking device, particularly for a vehicle parking brake, includes a casing (3) for supporting an electric motor (7) and a male-and-female screw unit (21, 23). The male-and-female screw unit comprises a rotatable element (21) connected for rotation with the output shaft (7a) of the electric motor (7) and an element (23, 25) which is slidable relative to the casing (3) as a result of the rotation of the rotatable element (21), the slidable element (23, 25) being associated with a transmission member (33) pivotable relative to the casing (3) and provided with a pair of arms to the ends of which respective brake-operating cables (41) are connected. The transmission member (33) is articulated to the slidable element (23, 25) of the male-and-female screw unit (21, 23) by means of at least one transverse pin (29) and the pin (29) engages a respective axial guide (32) of the casing (3) so that rotation of the slidable element (23, 25) relative to the casing (3) is prevented.
