摘要

A reservoir tank 5 that stores hydraulic fluid is equipped with a brake-use hydraulic fluid supply primary port 5a and a brake-use hydraulic fluid supply secondary port 5b that are disposed extending outward from a lower portion of an outer peripheral wall 5u and supply brake-use hydraulic fluid by means of inner holes 5j and 5o disposed extending into a primary fluid storage chamber 5f and a secondary fluid storage chamber 5g. Further, a primary fluid supply opening 5n and a secondary fluid supply opening 5r that allow the inner holes 5j and 5o disposed extending into the primary fluid storage chamber 5f and the secondary fluid storage chamber 5g to be communicated with the primary fluid storage chamber 5f and the secondary fluid storage chamber 5g are disposed orthogonal or substantially orthogonal with respect to the inner holes 5j and 5o.
