Abstract
A pressure regulating reservoir is structured such that a major diameter portion of a shaft contacts a bottom surface of a valve seat, whereas a top surface of a piston does not contact an upper end surface of a wall forming a reservoir chamber in a housing. Therefore, a lift amount of a ball valve can be set using a portion above the major diameter portion of the shaft that contacts the bottom surface of the valve seat. That is, the lift amount can be set using only a dimension in the axial direction of a minor diameter portion of the shaft.
