Abstract
This invention relates to a rotary shifter of a bicycle including: a fixing seat mounted on the handlebar of the bicycle; a rotary lever mounted on the fixing seat on an identical shaft axis as the handlebar; a drag member for driving a derailleur cable to enable a derailleur to change gears; a limit member for driving the drag member to engage in linear movement within a specific stroke; a rotary member for being driven by the rotary lever; a screw driving member located on the rotary member for driving the drag member to engage in linear movement along the specific stroke; a locating mechanism for locating the rotary member at an angular position corresponding to each gear of the derailleur; and an over shift device for enabling the drag member to produce extra displacement necessary for over shift of the derailleur to change gears.
