Claims

[Claims for Utility Model Registration] A first central hole provided in the center and a first hole provided on the outer circumferential side of the first central hole over a predetermined distance in the circumferential direction to avoid interference with the caliper. and at least two first mounting holes provided at predetermined intervals in the circumferential direction on the outer peripheral edge of the first central hole; and a central portion formed by burring. a second central hole provided in the central hole and having a larger diameter than the first central hole;
a second notch that is provided over a predetermined distance in the circumferential direction on the outer circumferential side of the second central hole in order to avoid interference with the caliper, and has a shape substantially similar to that of the first notch, and the second central hole; at least two second mounting holes provided at a predetermined interval in the circumferential direction on the outer peripheral edge of the dust cover, and a dish-shaped auxiliary plate having a diameter smaller than that of the dust cover main body, the auxiliary plate The second notch, the second center hole, and the second mounting hole of the dust cover body are positioned at positions corresponding to the first cutout, the first center hole, and the first mounting hole, respectively. The auxiliary plate is integrally fixed to the dust cover main body, so that an annular groove opening toward the outer circumference is formed between the dust cover main body and the auxiliary plate on the inside of the dust cover main body. In the dust cover for a disc brake, the width dimension of the two second mounting holes of the auxiliary plate in the direction of approaching and separating from the second notch is the same as the diameter of the first mounting hole of the dust cover main body, and Dust for a disc brake, characterized in that the length in the direction perpendicular to the direction is a predetermined dimension larger than the diameter of the first mounting hole, and the respective longitudinal center lines are formed by elongated holes located parallel to each other. cover.
