Abstract

Abstract This invention relates to a control device for use in controlling a two-speed derailleur via a control wire. The device comprises a fixing member (1) having a first pivot shaft (2) and a second pivot shaft (4) having its axis generally perpendicular to that of said first pivot shaft (2). A control lever (3) is pivotally mounted on said first pivot shaft (2), and displaceable between first and second speed change positions. A retaining means (35) is provided for retaining one end (S l ) of said control wire (W,). A release lever (5) is pivotally mounted on said second pivot shaft (4) on said fixing member (1) and displaceable at its distal end (5a) away from or towards said control lever (3). First and second biasing means (6, 7) are provided for biasing said control lever (3) towards its first speed change position and said release lever (5) at its distal end (5a) in a direction towards said control lever (3), respectively. Cooperating retaining means (34, 53) are provided on said control lever (3) and at the distal (5a) end of said release lever (5), for retaining said control lever (3) in its second speed change position against the biasing force of said first biasing means (6) through said release lever (5).
