A brake hydraulic pressure controller (20) capable of being formed with a relatively large damper chamber (190) while suppressing enlargement of its housing (130) is provided. The brake hydraulic pressure controller (20) includes: a motor (96) having a motor shaft (96a); a skew plate (125) fixed to a tip of the motor shaft (96a) and arranged to be inclined with respect to an axial direction of themotor shaft (96a); and a pump element (44) driven by rotation of the motor shaft (96a) and the skew plate (125). The pump element (44) has: a piston (150) that reciprocates in parallel with the axialdirection of the motor shaft (96a) in conjunction with the rotation of the skew plate (125); an accommodation chamber (161) that accommodates a part of the piston (150) and to which a brake fluid isintroduced; a release valve (180) that releases the brake fluid from the accommodation chamber (161); and a pressure damper chamber (190) that is provided in a reciprocal direction of the piston (150)and into which the brake fluid released from the release valve (180) flows.
提供能够在抑制外壳(130)的大型化的同时形成较大的缓冲器室(190)的制动液压控制装置(20)。制动液压控制装置(20)具有:马达(96),其具有马达轴(96a);斜板(125),其固定于马达轴(96a)的末端部,相对于马达轴(96a)的轴线方向倾斜地配置;和,泵元件(44),其借助马达轴(96a)和斜板(125)的旋转而被驱动。泵元件(44)具有:柱塞(150),伴随斜板(125)的旋转而与马达轴(96a)的轴线方向平行地往复移动;收纳室(161),其收纳柱塞(150)的一部分,被导入制动液;喷出阀(180),其从收纳室(161)喷出制动液;和,压力缓冲室(190),其沿柱塞(150)的往复移动的方向设置,从喷出阀(180)喷出的制动液流入其中。
