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; a click member having an engagement recess; (b) an engagement body holding member in which an engagement body capable of engaging and disengaging is formed in the engagement recess and is provided so as to be rotatable relative to the click member; 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 unrotatable relative to the lever shaft, and the boss-shaped base The one member configured to rotate substantially together with the base is freely rotatable at a predetermined angle relative to the boss-like base, so that the engaging body is able to rotate in the engaging recess of the click member. The lever main body can rotate within a certain angle range when engaged with one of the members, and the lever body can rotate relative to the boss-like base when it comes into contact with one of the members in the direction of rotation. an overshift amount variable mechanism that has a stopper operating body that restricts the movement of the stopper operating body, and that can increase or decrease the rotatable range of the one member relative to the boss-shaped base by performing a predetermined operation on the stopper operating body; A bicycle gear shift operation lever device, characterized in that it is provided with.
