PROBLEM TO BE SOLVED: To reduce and suppress vibration and noise caused by pulsation of brake fluid with a relatively simple configuration.SOLUTION: An elastic displacement member 34 constituting dampers 12a, 12b has a first displacement part 34c and a central displacement part 34b having different thicknesses. The first displacement part 34c having a smaller thickness than the central displacement part 34b forms the periphery of the central displacement part 34b. The elastic displacement member functions as a damper when brake fluid is under both low pressure and high pressure, and can reliably reduce and suppress vibration and noise caused by pulsation of the brake fluid.SELECTED DRAWING: Figure 2 |
