| description | To provide a disc brake capable of making a piston return more easily than conventional, when a brake is cancelled from a braking state.SOLUTION: In a disc brake, a seal groove 5 has a front wall 51, a rear wall 52 separated farther from a brake rotor than the front wall 51 in an axial direction D1, and a bottom wall 53 extending in the axial direction D1 between the rear wall 52 and the front wall 51. The bottom wall 53 has a front bottom wall 53a adjacent to the front wall 51, and a rear bottom wall 53b adjacent to the rear wall 52. Depth d2 of the rear bottom wall 53b from an inner periphery 42a of a cylinder 42 is larger than dimension d3 of a piston seal 6 under a non-compression state in a direction of the depth d2, and deeper than depth d1 of the front bottom wall 53a from the inner periphery 42a of the cylinder 42.SELECTED DRAWING: Figure 2
【課題】ブレーキをかけた状態からブレーキを解除するときに、従来よりもピストンを戻りやすくすることが可能なディスクブレーキを提供する。【解決手段】ディスクブレーキにおいて、シール溝５は、前壁５１と、その前壁５１よりもブレーキロータから軸方向Ｄ１に離れた後壁５２と、その後壁５２と前壁５１との間で軸方向Ｄ１に沿って延びる底壁５３と、を有する。底壁５３は、前壁５１に隣接する前底壁５３ａと、後壁５２に隣接する後底壁５３ｂとを有する。後底壁５３ｂは、シリンダ４２の内周面４２ａからの深さｄ２が、その深さｄ２の方向における非圧縮状態のピストンシール６の寸法ｄ３よりも大きくかつ前底壁５３ａのシリンダ４２の内周面４２ａからの深さｄ１よりも深い。【選択図】図２ |
