In a cable-operated device, one end of a coil spring 56 is fixed to a brake lever and another end of the coil spring 56 is fixed to a supporting member. At least one of the brake lever and the supporting member has a guide surface 58b making contact with the coil spring 56 from a lateral direction with respect to the coil spring 56. One end portion of the coil spring 56 has a first pitch portion 56b wound with a first pitch, a second pitch portion 56a wound with a second pitch which is smaller than the first pitch, and a third pitch portion 56c wound with a third pitch which is larger than the second pitch. When a primary load is applied to the coil spring 56, a length of the coil spring 56 is 80 to 120 mm, adjacent windings of the first pitch portion are separated from each other, adjacent windings of the second pitch portion are in contact with each other, and the second pitch portion makes contact with a tip end of the guide surface 58b. |
