Hydraulic pressure generation apparatus

A hydraulic pressure generation apparatus including:

• a base body;
• a motor attached to the base body;
• a reservoir tank which is attached to the base body and stores a brake fluid;
• a master cylinder which generates a brake hydraulic pressure by a first piston which is linked to a brake manipulator;
• and
• a slave cylinder which generates a brake hydraulic pressure by a second piston by the motor as a drive source,
• wherein the base body includes:
• a first cylinder hole which is a bottomed cylinder hole, and in which the first piston is inserted;
• a second cylinder hole which is a bottomed cylinder hole, and in which the second piston is inserted;
• and
• a supply passage which leads from the reservoir tank to a hydraulic chamber of the slave cylinder,
• wherein the supply passage is provided with a check valve which permits only inflow of brake fluid from the reservoir tank to a side of the slave cylinder, and
• wherein the check valve is disposed near a brake fluid discharge port of the second cylinder hole.
