Patent attributes
A brake dust cover is installed in a brake system including a rotor disposed on an inner diameter side of a rim of a wheel and a caliper interposing and holding the rotor with brake pads and includes a main body, an extension, and an opening. The main body is disposed adjacent to the rotor on an inside of the rotor in a vehicle width direction, that is disposed so as to overlap at least a part of the rotor when viewed from an axle direction, and that is disposed such that an outer circumferential edge portion thereof is separated from an inner circumferential surface of the rim. The extension extends from a part of the outer circumferential edge portion of the main body to an outer diameter side. The opening is formed in the main body, and air in a wheelhouse is introduced toward the rotor through the opening.
