GUIDING MECHANISM, NOTABLY FOR A BICYCLE DERAILLEUR

摘要

The object of the invention is to provide a mechanism whose construction and assembly are simplified and whose cost is consequently reduced. The mechanism comprises a support device, a movable device connected to the support device in such manner as to be movable in translation relative to the support device by an actuating device. The support device and movable device are mounted on an intermediate member to pivot about respective pivot pins. The two pivot pins are parallel to each other and the intermediate member defines two cavities which are parallel and extend in a direction orthogonal to the two pivot pins. Two push-members are slidably mounted in the two cavities and the ends of the push-members are respectively in contact with two parallel surfaces. One of the surfaces is defined on the movable device and the other is defined on the fixed device.
