Beschreibung
Zusammenfassung:	To provide a vehicular brake device that makes an opening part to be an inlet of a travel wind become a positive pressure area and an outer periphery of a disc rotor to be an outlet of the travel wind become a negative pressure area to increase an airflow speed using differential pressure between the positive pressure and the negative pressure, thereby improving cooling efficiency for the disc rotor.SOLUTION: A vehicular brake device includes: a dust cover 30 on an inner surface side in a vehicle width direction of a disc rotor 20; and an opening part 32 provided in the dust cover 30 to take a travel wind to an inner peripheral surface of the disc rotor 20, where an outer peripheral end of the dust cover 30 is in proximity to an inner peripheral surface of a rim part 5R of a wheel 5 in a non-contact state.SELECTED DRAWING: Figure 2 【課題】走行風の入口となる開口部を正圧領域とし、走行風の出口となるディスクロータ外周を負圧領域とし、正圧と負圧との圧力差により、空気流速を向上させ、これにより、ディスクロータの冷却効率向上を図ることができる車両用ブレーキ装置の提供を目的とする。【解決手段】ディスクロータ２０の車幅方向内面側にダストカバー３０を備え、上記ダストカバー３０に、上記ディスクロータ２０の内周面に走行風を取入れる開口部３２が設けられた車両用ブレーキ装置であって、上記ダストカバー３０の外周端を、ホイール５のリム部５Ｒの内周面に非接触状態で近接させたことを特徴とする。【選択図】図２
