Claims

[Scope of claim for utility model registration] Equip hole 1 in one of the pair of brake arms 1 and 2
0 is formed, and an eccentric shaft hole 17 is formed in the equipment hole 10.
A camshaft body 14 having a camshaft body 14 is rotatably inserted around its axis, and a wire holder 7 for receiving an end of a brake operation wire 5 is rotatably inserted into an eccentric shaft hole 17. In the brake release device, the first rotation regulating body 25 is fitted into the equipment hole 10 so as to be unrotatable with respect to the brake arm, and
The second rotation regulating body 33 is fitted onto the cam shaft body 14 so as to be relatively rotatable around the axis and movable in the axial direction, and the second rotation regulating body 33 is adjacent to the first rotation regulating body 25 in the axial direction. It is externally fitted and fixed to the cam shaft body 14 so as to
A spring member 38 is provided in the equipment hole 10 to urge the first rotation regulating body 25 in the axial direction toward the second rotation regulating body 33 , and the first rotation regulating body 25
and the second rotation regulating body 33 are provided with engaging portions 36 and 37 that engage with each other to restrict the relative rotation of the rotation regulating bodies 25 and 33, the entire circumference in the annular direction centering on the axis. A quick release device for a caliper brake, characterized in that it is formed in such a way that a large number of concave and convex portions are lined up over the entire length of the caliper brake.
