PROBLEM TO BE SOLVED: To provide a down-sized brake hydraulic pressure generator in which a decrease in brake fluid in one of two hydraulic passages is unlikely to affect the other hydraulic passage.SOLUTION: The brake hydraulic pressure generator includes: a first main hydraulic passage 11a; a second main hydraulic passage 11b; master cut valves each opening and closing each of the hydraulic passages 11a and 11b; a slave cylinder 40 working according to an operation amount of a brake operation element; a first communication passage 14a extending from the slave cylinder 40 to the hydraulic passage 11a; and a second communication passage 14b extending from the slave cylinder 40 to the hydraulic passage 11b. The slave cylinder 40 includes one hydraulic chamber 41b, and passes through a common channel 46 connected to the hydraulic chamber 41b to the communication passages 14a and 14b thereby to be able to raise a pressure in downstream of the hydraulic passage 11a or the hydraulic passage 11b. At least one of the communication passage 14a and the communication passage 14b is provided with an on-off valve.

    【課題】装置の小型化を図るとともに、二つの液圧路の一方の液圧路でブレーキ液が減少した場合にも、他方の液圧路に影響が及びにくくする。【解決手段】第一メイン液圧路11aおよび第二メイン液圧路11bと、液圧路11a,11bをそれぞれ開閉するマスタカット弁と、ブレーキ操作子の操作量に応じて作動するスレーブシリンダ40と、スレーブシリンダ40から液圧路11aに通じる第一連通路14aと、スレーブシリンダ40から液圧路11bに通じる第二連通路14bとを備え、スレーブシリンダ40は液圧室41bを一つ備え、液圧室41bに接続された共通流路46を介して連通路14a,14bに通じ、液圧路11aまたは液圧路11bの下流側を昇圧可能であり、連通路14aおよび連通路14bのうち少なくとも一方に開閉弁を設けた。【選択図】図1
