Claims

[Claims for Utility Model Registration] A lever body comprising a boss-shaped base having an operating cable fixing part and an operating cable winding groove on the outer periphery, and an arm extending in the radial direction from the boss-shaped base, In a bicycle gear shift operation lever device supported by rotatably fitting a center hole of a shaped base into a lever shaft, (a) a plurality of levers arranged at predetermined intervals in a circumferential direction centering on the lever shaft; (b) a click member having engagement recess groups at a plurality of locations, and (b) a holding hole for loosely holding an engaging body that can be engaged with and disengaged from the engagement recesses, corresponding to each of the engagement recess groups; (c) an engaging body holding member that is provided at each circumferential position around the lever shaft and is provided to be rotatable relative to the click member; a rotary operating body that has a contact surface that backs up the engaging body when positioned in the direction position to enable engagement between the engaging body and the engaging recess, and is provided so as to be rotatable around the lever axis; , wherein one of the click member and the engaging body holding member is configured to substantially co-rotate with the boss-shaped base, and the other is configured to be substantially unable to rotate relative to the lever shaft. On the other hand, at least one of the holding holes is formed to be larger in a circumferential direction around the lever shaft by a predetermined amount than the length of the engaging body in the circumferential direction; A bicycle shift operation lever device, characterized in that it is configured to be able to select each rotational position in which the lever is located at a position in the circumferential direction around the lever axis corresponding to each of the engaging bodies.
