摘要

The gear shift device for a bicycle consists of a main body (10) which on one side is formed as clamp (11) and on the other side is pivot-connected to a gear shift member (30) via a connecting rod (12). A L-shaped driver (20) is pivot-connected to the main body and at one end has a connecting component (22), and at a suitable point has a pivotable component (23) which is pivot-connected to the gear shift member, by means of which the gear shift member can be moved by the driver so that the gear shift chain can be brought into different shift positions.
