To provide an actuator device jointed so that a motor and a support member do not generate an axial mutual movement in a transmission for a bicycle.
The actuator device 1 for the transmission for the bicycle has an articulated quadrilateral mechanism 10 which is integrally mounted to a frame of the bicycle and a derailleur of the transmission, a motor member 2 which actuates on the articulated quadrilateral mechanism 10, deforms it and generates the displacement of the derailleur, and a support member 5 for the motor member 2 assembled with the articulated quadrilateral mechanism 10. Either the motor member 2 or the support member 5 has at least one protrusion member 8, and the other one of the motor member 2 and the support member 5 has at least one seating part 6 constituted so as to house the protrusion member 8.
