Claims

[Scope of utility model registration request]

In a disc rotor for a disc brake, a large number of ventilation holes extending in the radial direction and opening at both the inner and outer edges are provided radially and at approximately equal intervals in the annular sliding part to which the brake pad is pressed. The width in the thickness direction of the annular sliding part in a plurality of ventilation holes located at approximately equal intervals among the ventilation holes is formed to be the smallest width in the thickness direction compared to the width in the thickness direction in each of the other ventilation holes, and A disc rotor characterized in that the width in the thickness direction of each of the air holes located between the air holes having the minimum width is made wider as the air hole is located further away from the air hole having the minimum width.
