To provide a brake dust cover that compatibly improves brake cooling performance and suppresses deterioration in fuel economy while securing strength.SOLUTION: The present invention relates to a brake dust cover 1 which is arranged between a knuckle supporting an axle rotatably and a disk rotor rotating together with the axle so as to cover the disk rotor from inside in a vehicle width direction. The brake dust cover comprises a first plate-like member 10 in such a C shape that a circular ring is partially missing, and a second plate-like member 20 coupled to the first plate-like member 10. The second plate-like member 20 has a fixed part 25 fixed to the knuckle, and first to fourth support parts 21, 22, 23, and 24 extending radially from the fixed part 25. The first plate-like member 10 is laid over the first to fourth support parts 21, 22, 23, and 24 and coupled so as to form first and second opening parts 3, 5 between an inner edge 10b of the first plate-like member 10 and an outer edge 25a of the fixed part 25 when viewed from the vehicle width direction.SELECTED DRAWING: Figure 1

    【課題】ブレーキダストカバーにおいて、強度を確保しつつ、ブレーキ冷却性能の向上と燃費悪化の抑制とを両立させる。【解決手段】車軸と共に回転するディスクロータを車幅方向内側から覆うように、車軸を回転可能に支持するナックルとディスクロータとの間に配置されるブレーキダストカバー1である。円環の一部が欠けたC字状の第1板状部材10と、第1板状部材10と結合される第2板状部材20と、を備えている。第2板状部材20は、ナックルに固定される固定部25と、固定部25から放射状に延びる第1〜第4支持部21,22,23,24と、を有している。第1板状部材10は、車幅方向から見て、第1板状部材10の内縁10bと固定部25の外縁25aとの間に第1および第2開口部3,5が形成されるように、第1〜第4支持部21,22,23,24に重ねられて結合されている。【選択図】図1
