  • Patent number: 11761474
    Abstract: A control cable connection structure includes a long, narrow casing, a casing end, a cable end and a slider. An end portion of a first conduit is anchored at one end portion, in a length direction, of the casing. An end portion of a second conduit is anchored at the casing end. The casing end is superposed and assembled with the casing in a radial direction of the second conduit. The cable end is attached to an end portion of a second inner cord. An end portion of a first inner cord is anchored at the slider. The slider is supported at the casing to be slidable in the length direction thereof. In the assembled state, the cable end is engaged with the slider at an opposite side from a side at which the second conduit is disposed, and the second inner cord is connected with the slider.
