を特徴とするデイスクブレーキキヤリパ。 A rubber ring held in the inner periphery of the annular groove on the inner surface of the cylinder is brought into close contact with the outer periphery of the brake piston built into the cylinder with an interference margin, and this rubber ring forms a liquid seal between the brake piston and the cylinder, and when pressurized. In a disc brake caliper, the brake piston is pulled back by a predetermined amount when the pressure is removed by the elastic restoring force of the rubber ring, which is elastically deformed when dragged by the piston.The anti-liquid seal in the annular groove regulates the amount of elastic deformation of the rubber ring when pressure is applied. The amount of chamfering of the side gutter edge chamfer is small on the outer circumference side of the disk and large on the inner circumference side,
Furthermore, the disc brake caliper is characterized in that the difference in the amount of chamfering is approximately equal to the difference in the amount of deformation in the axial direction of the disc due to the normal hydraulic pressure of the caliper at the position of the piston in the radial direction of the disc.
