Abstract:
1. Actuator device for a bicycle gearshift, comprising: an articulated quadrilateral mechanism intended to be integrally fixed to a bicycle frame and to a derailleur of the gearshift; a motor member extending along a drive axis and having a drive shaft acting on said articulated quadrilateral mechanism to deform the articulated quadrilateral thus determining the displacement of said derailleur, and at least one jutting element; a support element, for said motor member associated with the articulated quadrilateral, that includes at least one seat defined by a single slot that is perpendicular to the drive axis along an entire length of said slot and terminates at a peripheral edge of a side wall of said support element and is adapted to receive said at least one jutting element, said side wall of said support element being substantially parallel to said drive axis; and engagement between the at least one jutting element and the seat prevents displacement of the motor member with respect to the support.
