The tag 19 passes through one of the openings 18 and is held in place by being folded back as shown in FIG. Therefore, there is a problem that the damping device for the disk becomes complicated. Therefore, the present invention was devised to solve these problems, and provides a squeal-preventing ventilated disk with a simplified damping device.

Air is quickly exhausted from the outer opening of the vent.

５，５が形成されている。(Embodiment) Figures 1 to 4 show an embodiment of a ventilated disk according to the present invention, in which rotor bodies 2, 2 are connected by a large number of ribs 1, 1 extending in the radial direction, and the ribs 1, A large number of ventilation holes 3, 3 are provided by the rotor body 1 and the rotor bodies 2, 2, and an annular member 4 made of a steel bar material, for example, a ring made of stainless steel, is secured to the outer peripheral end surface of the ribs 1, 1. The part of the annular member 4 that engages with the ribs 1, 1 is formed wider than the part of the annular member 4 that engages with the ventilation holes 3, 3, so that the annular member 4 is in close contact with the ribs, and the rotor main body 2, 2
Outer openings 5, 5 of the ventilation holes 3, 3 are formed between the annular member 4 and the annular member 4.

環状部材４で吸収して早期に減衰させる。 When the disk rotates, the air in the vent holes 3, 3 is quickly discharged to the outside from the outer openings 5, 5 of the vent holes 3, 3 due to centrifugal force, and new air flows in from the inner openings of the vent holes 3, 3. and rotor body 2, 2
to cool down. Further, the vibrations of the rotor bodies 2, 2 that occur during braking are transmitted to the annular member 4, and the vibrations are absorbed by the annular member 4 and quickly damped.

Since the brake is damped early, a good damping effect can always be obtained, and the squeal that occurs during braking is reduced. Furthermore, the rotation of the disk allows for good air circulation into the ventilation holes, resulting in a good cooling effect.
A stable braking effect can be obtained.
