Zusammenfassung: | PROBLEM TO BE SOLVED: To effectively control leakage of working fluid through a remaining air releasing passage even when a working fluid inlet of a reservoir tank is largely tilted downwardly.SOLUTION: A cap 18 has a space surrounded by a cylindrical side wall 20a of a baffle 20, a bottom part 20b of the baffle 20, and a diaphragm 21. The space is communicated with the inside of a reservoir tank through baffle side ventilation holes 20h, 20i formed in the bottom part 20b. Further, the space is communicated with the outside of the reservoir tank through a diaphragm side ventilation hole formed in the diaphragm 21. The diaphragm side ventilation hole is formed in a bent exhaust passage formed by a first diaphragm side ventilation hole 21a, and a second diaphragm side ventilation hole 21c extending in the radial direction of a projecting part 21b so as to be orthogonal to the first diaphragm side ventilation hole 21a. |
