Summary:To provide a disk brake capable of smoothly extracting air during filling of brake fluid.SOLUTION: A cylinder bore 35 which slidably stores a piston 21 pressing one of a pair of pads 3, 4 and to which brake fluid pressure is supplied, and a bleeder hole 122 which communicates the cylinder bore 35 with the outside are formed in a caliper 5. An inner bottom surface 38 of the cylinder bore 35 includes a deep bottom surface 201, and a shallow bottom surface 202 formed between the deep bottom surface 201 and the bleeder hole 122 and arranged so that a gap between a confronting portion of the piston 21 and the shallow bottom surface 202 is narrower than a gap between the confronting portion of the piston 21 and the deep bottom surface 201.SELECTED DRAWING: Figure 3 【課題】ブレーキ液の充填時にエアを円滑に抜くことが可能となるディスクブレーキを提供する。【解決手段】キャリパ５に、一対のパッド３，４のうちの一方を押圧するピストン２１を摺動可能に収容するとともにブレーキ液圧が供給されるシリンダボア３５と、シリンダボア３５を外部に連通させるブリーダ孔１２２とが形成されており、シリンダボア３５の内底面３８は、深底面部２０１と、深底面部２０１とブリーダ孔１２２との間に形成され、ピストン２１の対向部分との間隔が深底面部２０１よりも狭くなるように配置される浅底面部２０２と、を有する。【選択図】図３
