Abstract: To achieve a brake hydraulic pressure control system which makes it possible to suppress an increase of the manufacturing cost as compared to existing brake hydraulic pressure control systems which ground a control board using a coil spring. A brake hydraulic pressure control system according to the present invention includes: a metallic substrate (80) in which a flow channel for brake fluid is formed; and a control board (76) of a hydraulic pressure control mechanism for the brake fluid provided in the flow channel. The brake hydraulic pressure control system according to the present invention further includes at least one conductive plate spring (90) which is provided between the control board (76) and a component that is electrically connected to the substrate (80).

Abstract: To achieve a brake hydraulic pressure control system for a straddle-type vehicle which makes it possible to reduce its size as compared to existing ones. A brake hydraulic pressure control system (70) according to the present invention including: a substrate (80); a motor (40) which is a brushless motor configured to drive a pump device (31); a housing (85) which is connected to the substrate (80); and a detection mechanism (60) which is configured to detect the rotation state of an output shaft (45) of the motor (40), in which the motor (40) is disposed in a space surrounded by the substrate (80) and the housing (85), and a bearing (46) of the motor (40) is inserted into a concave part (84) formed in the substrate (80).

Abstract: To achieve a brake hydraulic pressure control system for a vehicle which makes it possible to reduce its size as compared to existing ones. A motor (40) of a brake hydraulic pressure control system (70) according to the present invention is a brushless motor, and is disposed in a space surrounded by a substrate (80) and a housing (85). A stator (41) of the motor (40) includes a coil (42) and a mold part (43) covering the coil (42) with a mold member. The mold part (43) is in contact with a motor housing (50) of the motor (40). The brake hydraulic pressure control system has such a configuration that heat generated by the coil (42) is transmitted to an object, which is in contact with the motor housing (50), by way of the mold part (43) and the motor housing (50).
