Claims (1)

[Scope of utility model registration request] This is an adjustment device for a bicycle operating rope that is stretched between a speed change operating device equipped with a positioning mechanism and a transmission that changes a chain to one sprocket of a multi-stage sprocket device, and includes a mounting body 2 and the mounting body. 2, it has a cylindrical shaft part 31 that is attached to be movable in the axial direction by rotational operation, and a head 32 that has a larger diameter than the cylindrical shaft part 31 and supports one end of the operating cable, and adjusts the length of the operating cable. A rotary operating body 4, which cannot rotate with respect to the head 32 and is movable in the axial direction, is fitted on the outer periphery of the head 32 of the adjusting body 3. 4, the mounting body 2
A cylindrical extension part 41 extending in the direction is provided, and a spring 5 is provided between the axially opposing surfaces of the cylindrical extension part 41 and the head 32 to bias the operating body 4 in the direction of the mounting body 2. In addition, a click mechanism is provided between the cylindrical extension part 41 and the mounting body 2 to prevent rotation of the operating body 4 in stages and to give a click feeling to the rotation of the operating body 4. Adjustment device for bicycle control cables.
