Claims

[Scope of utility model registration request]

A bearing hole is provided in the caliper arranged to straddle the disk rotor, perpendicular to the disk shaft, and the insertion shaft of the camshaft is arranged in the bearing hole. In a mechanical vehicle disc brake that presses a friction pad against a disc rotor by rotating it in the direction of the disc axis, a friction pad is attached to either the insertion shaft of the camshaft or the bearing hole depending on the amount of rotation of the camshaft. The circumference of a camshaft in a mechanical disc brake for a vehicle, characterized in that a guide recess of a corresponding size is formed, and an engagement protrusion that engages with the guide recess and restricts the amount of rotation of the camshaft is provided on the other side. Stop structure.
