PURPOSE: To simplify the structure, reduce the production cost, and allow a user to perform a wide regulation by providing an auxiliary support having the pin of a gear-operating lever mounted thereon on a body mount seat in such a manner as to be slidable and rotatable, and providing an elastic means between a brake-operating lever and a body. CONSTITUTION: A user can change the distance from a grip 2 to a derailer- operating lever 11 by loosening a screw 13 and also change the inclination of the rotating axial line Y-Y of the lever 11 to a handle bar 1 by loosening a screw 15. Thus, the final position of the stroke of the lever 11 determining the continuous angles of the lever corresponding to various gear ratios can be changed. Since an auxiliary support 8 has a special form, the lever 11 can be mounted on the upper or lower side of the middle plane determined by the bar 1 and a brake-operating lever 5, and the user can hold the lever 11 in a favorable state. Further, one end 19a of a plate spring 19 is elastically installed on the mount seat 18 of the lever 5, and the other end 19b acts on the body of a support 3 to return the lever 5, when the lever 5 is moved, by the elastic deformation of the spring 19. |
