個所以上で溶接によつて固着されている。(Prior art) There is a disk rotor that takes measures to prevent squealing during braking, as shown in Japanese Utility Model Application Publication No. 54-52576, which consists of an annular sliding part and a cylindrical hat part. An annular groove is formed around the entire circumference of the annular sliding part, a metal wire is wound around the annular groove so as to engage with the annular groove, and the metal wire is wrapped around the outer periphery of the annular sliding part. It is fixed by welding at one or more places to the

る。(Problem to be solved by the invention) In conventional disc rotors, due to the difference in thermal expansion coefficient between the sliding part and the metal wire, the non-welded part of the metal wire lifts up from the annular sliding part, which occurs during braking. There is a problem that the vibration of the disc rotor cannot be completely absorbed. The present invention was devised to solve this problem, and aims to quickly attenuate the vibrations of the disc rotor that occur during braking by improving the sliding parts.
