Claims

[Scope of utility model registration request]

By providing a plurality of ventilation holes radially in the friction part that has friction surfaces on both the front and back sides, penetrating from the inner circumference side to the outer circumference side, and with the inner circumference side opening on both the front and back sides, ribs are created between adjacent ventilation holes. A brake disc characterized in that the extending direction of the ribs intersects the rotation center line of the friction portion.
