第1実施形態のディスクブレーキ10において、位置決め用プレート部193にかえて、図26~図28に示すような位置決め用プレート部193Aを設けても良い。この位置決め用プレート部193Aは、湾曲板部211に対して一部異なる湾曲板部211Aを有している。湾曲板部211Aは、湾曲板部211Aを板厚方向(径方向)に貫通する丸穴状の孔251Aが複数整列状態で形成されている点が湾曲板部211に対して相違している。よって、湾曲板部211Aは、内側曲面部211aに対して複数の孔251Aが開口する点が相違する内側曲面部211Aaを有しており、外側曲面部211bに対して複数の孔251Aが開口する点が相違する外側曲面部211Abを有している。位置決め用プレート部193Aは、いわゆるパンチングメタルである。このような位置決め用プレート部193Aを用いれば、ブレーキダストを含む空気を複数の孔251Aを介して集塵部191内へ良好に流すことができるため、ブレーキダストを集塵部191で、より一層効率良く回収することが可能となる。
