Abstract

PURPOSE:To reduce the creak of a brake by shifting the positions of connected parts of both sliding friction plates of the fins in a ventilated disc rotor so that the phases of frictional vibrations which are generated by the rotor and both pads upon braking, are shifted. CONSTITUTION:Fins 1 defining ventilating holes with both sliding friction plates 2, 3 fixed together therethrough, are formed so as to be inclined at an angle alpha with respect to the both sliding friction plates 2, 3, thereby connected positions by the fins 1 on both sliding friction plates 2, 3, which correspond to convex parts 2a, 3a on the sliding friction surfaces of the plates 2, 3 and are subjected to the influence of frictional heat generated by both pads slidingly contacted thereto, are shifted. Due to the shift of the connected positions of both plates, the phases of frictional vibrations generated upon braking by a rotor and both pads, are shifted relatively to each other so that unpleasant sound (creak) generated from the brake is reduced.
