BRAKE HYDRAULIC PRESSURE CONTROLLER

[Problem] A brake hydraulic pressure controller capable of being formed with a relatively large damper chamber while suppressing enlargement of a housing is provided. [Means for Resolution] The brake hydraulic pressure controller includes: a motor having a motor shaft; a skew plate fixed to a tip of the motor shaft and arranged to be inclined with respect to an axial direction of the motor shaft; and a pump element driven by rotation of the motor shaft and the skew plate. The pump element has: a piston that reciprocates in parallel with the axial direction of the motor shaft in conjunction with the rotation of the skew plate; an accommodation chamber that accommodates a part of the piston and to which a brake fluid is introduced; a release valve that releases the brake fluid from the accommodation chamber; and a pressure damper chamber that is provided in a reciprocal direction of the piston and into which the brake fluid released from the release valve flows.
