Claims

[Scope of utility model registration request]

In the ventilated type disk rotor, a large number of ribs connecting the opposing surfaces of two disc-shaped outer and inner sliding surface disks are formed radially with respect to the axis. A ventilated type disk rotor characterized in that a small hole for stress absorption is bored in the outer disk from the inner end, which is the axis side of the rib, to the axis side.
