Abstract: A lever mechanism for a cable linkage includes a control lever mounted on a rotary shaft for rotation therewith, a base plate mounted on the rotary shaft and fixed to the control lever for rotation therewith, and a lever plate adjustably assembled with the base plate and connected at one side of its outer peripheral portion to one end of the cable linkage, the lever plate being provided at its outer peripheral portion with a semicircular guide surface the center of which is located substantially at a rotation fulcrum of the lever plate. The cable linkage is supported on the semicircular guide surface of the lever plate, and the lever plate is displaceable on the base plate during the assembly process thereof to adjust the distance between the semicircular guide surface and the rotation fulcrum.
