PROBLEM TO BE SOLVED: To provide a technology having small and inexpensive output generation means and capable of achieving the reduction of a number of components as well as component cost.SOLUTION: A pressure regulation mechanism 40 comprises a stepped piston 41 having a large diameter part 42 and a small diameter part 43, and a cylinder 44 which accommodates the stepped piston 41 slidably. The cylinder comprises: a large diameter chamber 45 to which the large diameter part is disposed, and a second hydraulic passage 16 is connected; a small diameter chamber 46 in which the small diameter part 43 is disposed, and which is connected to a first hydraulic passage 15; and a piston energizing member 47 for energizing the stepped piston 41 to the small diameter chamber 46 side. Thereby, fluid pressure generation means, which is an output source, can be made small and inexpensive since there is no need to generate pressure larger than pressure in the small diameter chamber connected to a master cylinder.
【課題】小型且つ安価な出力発生手段を有し、少ない部品点数で部品コストの削減を図ることができる技術を提供する。【解決手段】圧力調整機構40は、大径部42および小径部43を有する段付きピストン41と、この段付きピストン41を摺動可能に収容するシリンダ44とで構成されている。このシリンダ44は、大径部42が配置され且つ第2液圧路16が接続される大径室45と、小径部43が配置され且つ第1液圧路15に接続される小径室46とを有するとともに、段付きピストン41を小径室46側に付勢するピストン付勢部材47が設けられている。【効果】マスタシリンダに接続される小径室の圧力よりも大きな圧力を発生させる必要がないので、出力源である液圧発生手段を小型且つ安価にできる。【選択図】図1
