<p>PROBLEM TO BE SOLVED: To enable at full braking, reduction of volume consumption and extension of a pedal stroke following the same.SOLUTION: A valve seat 18.1 arranged on the marginal part of a penetration part 18 is sealed with a valve body 9 by a closing member 16, and an opening member 20 penetrates the penetration part 18 of the valve body 9 and is movable by a reservoir piston 10, and a reservoir piston stroke KH in the axial direction initiates an opening stroke SH in the axial direction of the closing member 16 through the opening member 20. When a volume in a reservoir chamber 7 becomes smaller than a prescribed threshold, the closing member 16 is pushed out from the valve seat 18.1 by the opening member 20 so as to be moved from a closed position to an opened position.</p> |
