Claims (1)

[Claims for Utility Model Registration] 1. The cross section from the inner peripheral side bracket part attached to the hub of the wheel to the connecting part extending from the outer peripheral edge thereof is approximately L-shaped, and the bracket part is connected to the bracket part through the connecting part. In the disk of the disc brake device, which has a roughly hatched shape and is integrated with the pad clamping pressure part on the outer peripheral side by forming a step, the disc has a roughly L-shape that protrudes in the opposite direction to the cross-sectional shape from the bracket part to the connecting part. 1. A disc structure for a disc brake device, characterized in that a deformation suppressing protruding piece part having a shaped cross section and extending from the inner peripheral edge of the pad clamping pressure part to the bracket part is integrally formed. 2. The disc structure of the disc brake device according to claim 1, wherein the deformation-suppressing protruding piece part is arranged at a position avoiding the bolt arrangement part.
