PROBLEM TO BE SOLVED: To reduce, for example, a difference in operation feeling between when temperature is low and when temperature is normal, in a hydraulic brake system in which a stroke simulator and a pump are connected.SOLUTION: A stroke simulator 48s and a suction mechanism 40 are connected by a first passage 60 and a second passage 62 provided with a diaphragm 70. A first connection part 64 of the first passage 60 is provided closer to the pump 32 than a second connection part 66 of the second passage 62. When temperature is low, a hydraulic liquid is less likely to be supplied to the second connection part 66 via the second passage 62. When temperature is normal, the hydraulic liquid is easily supplied to the second connection part 66 via the second passage 62. As a result, a stroke increase resulting from a suction operation of the pump 32 is restricted when temperature is normal than when temperature is low. Accordingly, a difference in operation feeling between when temperature is normal and when temperature is low can be reduced.SELECTED DRAWING: Figure 1

    【課題】ストロークシミュレータとポンプとが接続された液圧ブレーキシステムにおいて、例えば、低温時と常温時とでの操作フィーリングの差を小さくする。【解決手段】ストロークシミュレータ48sと吸入機構40とが第1通路60と絞り70が設けられた第2通路62とによって接続され、第1通路60の第1接続部64が第2通路62の第2接続部66より前記ポンプ32に近い側に設けられる。低温時には、第2通路62を経て第2接続部66へ作動液が供給され難いが、常温時には低温時より、第2通路62を経て第2接続部66へ供給され易くなる。その結果、常温時には低温時より、ポンプ32の吸入作動に起因するストロークの増加が抑制されるのであり、常温時と低温時とでの操作フィーリングの差を小さくすることができる。【選択図】図1
