Brake hydraulic pressure control apparatus

A brake hydraulic pressure control apparatus (20) configured to control a hydraulic pressure in plural systems of hydraulic circuits (28, 30), the brake hydraulic pressure control apparatus comprising:

• a pressure supply unit (90) that includes a motor (96) and a pump element (80);
• and
• a hydraulic block (130) that includes an oil channel connected to the pressure supply unit (90) and control valves (34, 36, 54, 58) regulating a hydraulic pressure in each of the plural systems of the hydraulic circuits (28, 30), wherein
• the pressure supply unit (90) includes:
• the motor (96) having a stator (97) and a rotor (98);
• a swash plate (127) arranged to be tilted with respect to an axial direction of a rotation axis of the rotor (98);
• and
• the pump element (80) having plural pump sections (44) driven by rotation of the motor (96), and
• at least a part of the pump element (80) is arranged in the rotor (98) wherein
• the pressure supply unit (90) is attached to one side surface (130a) of the hydraulic block (130),
• the pump element (80) has:
• an introduction channel (169) through which hydraulic oil is introduced;
• and a discharge channel (179) from which the hydraulic oil is discharged, and
• each of the introduction channel (169) and the discharge channel (179) is opened to a surface opposing the one side surface (130a) of the hydraulic block (130), and
• wherein the brake hydraulic pressure control apparatus further includes seal rings (202a, 202b) around a connected portion between the introduction channel (169) of the pressure supply unit (90) and the oil channel of the hydraulic block (130) and around a connected portion between the discharge channel (179) of the pressure supply unit (90) and the oil channel of the hydraulic block (130).
