変速操作装置。 It includes a fixing member 2 and a lever body 3 that rotatably supports the fixing member 2, and these fixing members 2
and the lever body 3, a positioning body 41 having a plurality of engaging parts 41a, an engaging body 42 that selectively engages with one of the engaging parts 41a, and the engaging body 42.
A bicycle gear shift operating device is provided with a positioning mechanism 4 consisting of a plate-shaped pressing spring 43 that presses the engaging portion 41a toward the engaging portion 41a.
A gap K is provided between the lever body 3 and the pressing spring 43 to allow the lever body 3 to freely rotate within a certain range when the lever body 3 is moved forward in a direction opposite to the operating direction of the return spring in the transmission. The mechanism 4 includes force equalizing means for equalizing the difference between the operating force when operating the lever body 3 forward and the operating force when operating the lever body 3 backward in the direction of action of the return spring. A bicycle gear shift operation device characterized in that:
