Hydraulic pressure control unit, brake system, and straddle-type vehicle

A straddle-type vehicle (200) comprising:

• a front wheel (217) that is held in a freely rotatable manner by a front fork (216);
• a brake system (100) that includes a hydraulic pressure control unit (1) and capable of executing anti-lock brake control,
• the hydraulic pressure control unit (1) comprising:
• a base body (10) formed with:
• a master cylinder port (11) to which a fluid pipe (101) communicating with a master cylinder (242) is connected;
• a wheel cylinder port (12) to which a fluid pipe (102) communicating with a wheel cylinder (251) is connected;
• and an internal channel (13) that communicates the master cylinder port (11) and the wheel cylinder port (12) with each other;
• an inlet valve (31) and an outlet valve (32) that are provided to the base body (10) and open/close the internal channel (13) during the anti-lock brake control;
• a first coil (61) as a drive source of the inlet valve (31);
• a second coil (62) as a drive source of the outlet valve (32);
• a circuit board (36) that is electrically connected to the first coil (61) and the second coil (62) and configured to control energization of the first coil (61) and the second coil (62);
• and
• an accumulator (33),
• wherein the hydraulic pressure control unit (1) is configured to store a brake fluid that is released from a wheel cylinder (251) during depressurization in the anti-lock brake control in an accumulator (33) and to discharge the brake fluid in the accumulator (33) to outside of the accumulator (33) in a pumpless manner,
• wherein the base body (10) is held by the front fork (216), and
• in a state where the straddle-type vehicle (200), to which the hydraulic pressure control unit (1) is mounted, is seen in a front view, the circuit board (36) is located behind the front fork (216) and the base body (10), and the first coil (61) and the second coil (62) are erected from a rear surface (28) of the base body (10).
