PROBLEM TO BE SOLVED: To provide strong fixing force by forming an isotropic recess- projection on a surface contacting with an inner cable of a light alloy-made disk in order to prevent sliding with the inner cable. SOLUTION: A wire fixing plate 11 is an annular disk formed into a circular ring shape. One surface side, that is, a bolt side end surface 13 is almost flatly formed, and the other surface side, that is, a wire side end surface 14 is composed of concentric two-strip circular grooves 16 and 17 by applying a recess projection pattern 15. A crossing angle (an angle on a cross section orthogonal to the wire side end surface 14 containing a radial line) of both side inclined faces to form the respective circular grooves 16 and 17 is almost 80 degrees to 100 degrees. The wire fixing plate 11 is formed of aluminum alloy to reduce weight. An inner cable bites in a sharp circular continuous projection of about 90 degrees. This biting-in force or meshing force increases as tensile force of the inner cable becomes large by means of a wedge effect. |
