Claims

[Claims for Utility Model Registration] 1. A bearing hole perpendicular to the disk axis is provided in one side wall of the acting part of the caliper disposed on the side of the disk rotor, and the friction pad is inserted into the bearing hole as described above. In a mechanical disc brake for a vehicle in which a camshaft that presses against a disc rotor is rotatably inserted and inserted, a flange is provided on the outside of the opening of the bearing hole, and a flange is provided on the outside of the opening of the bearing hole, and a flange is provided on the outside of the opening of the bearing hole, and the flange is engaged with the protruding shaft portion of the camshaft that protrudes from the bearing hole. A lever retaining member having an arm is fixedly provided, and the tip of the engaging arm is folded into the opposite side across the outer circumference of the flange, and comes into contact with the tip of the engaging arm to restrict the amount of rotation of the camshaft. A mechanical disc brake for a vehicle, characterized in that a stopper is provided on the flange to stop the brake. 2. A bearing hole perpendicular to the disk axis is provided in the action part of the caliper disposed on the side of the disk rotor, and a camshaft for pressing the friction pad against the disk rotor is rotated in the bearing hole. In a mechanical disc brake for a vehicle that is movably inserted and arranged, an arc-shaped guide groove centered on the axis of the bearing hole is formed outside the opening of the bearing hole,
A lever retaining member having an engaging arm is fixed to the protruding shaft portion of the camshaft protruding from the bearing hole, and the distal end of the engaging arm is inserted into the guide groove and folded into the inner surface, A mechanical disc brake for a mechanical vehicle, characterized in that the distal end of the engagement arm is brought into contact with the end of the guide groove to restrict the amount of rotation of the camshaft.
