- 16. The derailleur according to claim 15 wherein an end of the screw abuts against a surface of the other one of the first actuating member and the second actuating member.
- 17. The derailleur according to claim 8 further comprising a second position adjuster for adjusting a position of the first actuating member relative to the second actuating member.
- 18. The derailleur according to claim 17 wherein the first actuating member is rotatably coupled to the second actuating member for rotation around a rotational axis.
- 19. The derailleur according to claim 18 wherein the second position adjuster is coupled between the first actuating member and the second actuating member at a location spaced apart from the rotational axis.
- 20. The derailleur according to claim 19 wherein the second position adjuster comprises a screw that is screwed into one of the first actuating member and the second actuating member.
- 21. The derailleur according to claim 20 wherein an end of the screw abuts against a surface of the other one of the first actuating member and the second actuating member.
- 22. The derailleur according to claim 21 wherein the first position adjuster is coupled between the first actuating unit and the second actuating unit.
- 23. The derailleur according to claim 22 wherein the first position adjuster comprises a first screw that is screwed into one of the first actuating unit and the second actuating unit, and wherein the second position adjuster comprises a second screw that is screwed into one of the first actuating member and the second actuating member.
- 24. The derailleur according to claim 23 wherein an end of the first screw abuts against a surface of the other one of the first actuating unit and the second actuating unit, and wherein an end of the second screw abuts against a surface of the other one of the first actuating member and the second actuating member.
- 25. A derailleur comprising:
a base member; a movable member coupled for moving relative to the base member and supporting a chain guide; a first actuating unit for moving the movable member relative to the base member; a second actuating unit for moving the first actuating unit through an abutment; wherein the second actuating unit comprises a first actuating member movably coupled to a second actuating member; and a position adjuster that adjusts a relative position between the first actuating member and the second actuating member.
- 26 The derailleur according to claim 25 wherein the first actuating member includes a wire winding surface.
- 27. The derailleur according to claim 26 wherein the second actuating member rotates around a first rotational axis.
- 28. The derailleur according to claim 27 wherein the position adjuster adjusts a radial position of the wire winding surface relative to the first rotational axis.
- 29. The derailleur according to claim 28 wherein the first actuating member is rotatably coupled to the second actuating member for rotation around a second rotational axis.
