To provide a liquid pressure control unit and a saddle-riding type vehicular brake system capable of satisfying requirement of size reduction.SOLUTION: A saddle-riding type vehicular brake system comprises a liquid pressure circuit comprising: a main channel for circulating a brake liquid of a master cylinder to a wheel cylinder; a sub channel for releasing the brake liquid of the wheel cylinder into a middle part of the main channel; and a supply channel for supplying the brake liquid to the middle part of the sub channel. In front view of a surface where a motor 28 of a substrate 51 of the liquid pressure control unit is erected, an opening of a first valve 31 for controlling a flow rate on the wheel cylinder side on the middle part of the main channel and an opening of a second valve 32 for controlling a flow rate on the upstream side of the middle part of the sub channel, are overlapped in a first straight line L1, an opening of a third valve 35 for controlling a flow rate on the master cylinder side of the middle part of the main channel and an opening of a fourth valve 36 for controlling a flow rate on the supply channel are overlapped in a second straight line L2 orthogonal to the first straight line L1.SELECTED DRAWING: Figure 5
【課題】小型化の要請に応え得る液圧制御ユニット及び鞍乗型車両用ブレーキシステムを得る。【解決手段】鞍乗型車両用ブレーキシステムは、マスタシリンダのブレーキ液をホイールシリンダに流通させる主流路と、ホイールシリンダのブレーキ液を主流路途中部に逃がす副流路と、副流路途中部にブレーキ液を供給する供給流路と、を備えた液圧回路を含み、液圧制御ユニットの基体51のモータ28が立設された面を正面視した状態において、主流路途中部のホイールシリンダ側を流量制御する第1バルブ31のための開口、及び、副流路途中部の上流側を流量制御する第2バルブ32のための開口が、第1直線L1に重なり、主流路途中部のマスタシリンダ側を流量制御する第3バルブ35のための開口、及び、供給流路を流量制御する第4バルブ36のための開口が、第1直線L1に直交する第2直線L2に重なる。【選択図】図5
