PURPOSE:To form a reservoir, provided with a chamber for storing operating oil for a master cylinder and a chamber for storing operating oil for hydraulic booster in a single reservoir body, in such a way as to get operating oil, returned from a hydraulic booster, into the normal deformed state in the latter chamber before the delivery of the operating oil to a hydraulic pump. CONSTITUTION:The inside of a reservoir body 12 is partitioned by a cylindrical partition wall 29 into a center chamber 30 for storing operating oil for a master cylinder, and an outer chamber 31 surrounding the center chamber 30. The outer chamber 31 is further partitioned by a sheahing plate 36, a partition wall 35 and a filter plate 43 into three chambers, that is, a delivery chamber 32, a filter chamber 33 and a defoaming chamber 34, and the delivery chamber 32 is communicated with the center chamber 30 through a communicating part 37. A delivery pipe connected to the inflow port of a hydraulic booster is connected to the delivery chamber 32, and a return pipe 5 connected to the outflow port of the hydraulic booster is connected to the filter chamber 33. |
