Brake disc

摘要

A brake disc is provided capable of effectively reducing the generation of noise such as brake noise by making specifications relating to lightening holes different from each other between two brake disc plates. In the brake disc, two brake disc plates are laminated so as to slide on each other by vibration during braking, and specifications relating to one or more selected from lightening holes, plate thickness, diameter, and warpage are made different from each other between the brake disc plates. In addition, lightening holes are formed on at least one of the brake disc plates, and one or more specifications selected from the number of lightening holes, the shapes of the lightening holes, the sizes of the lightening holes, and the arrangement positions of the lightening holes are made different from each other between the brake disc plates.
