ABSTRACT:
An actuator device for a bicycle gearshift is provided. The actuator device having an articulated quadrilateral mechanism intended to be integrally fixed to a bicycle frame and to a derailleur of the gearshift, a motor member that acts on the articulated quadrilateral mechanism to deform the articulated quadrilateral, and displaces the derailleur and a support element for the motor member associated with the articulated quadrilateral. According to the invention, one of the motor member and the support element comprises at least one jutting element and the other of the motor member and the support element comprises at least one seat adapted to receive said jutting element. Thus, the motor member is associated with the support element so as to prevent mutual translations in the axial direction in any operating or climatic condition.
