Beschreibung
Zusammenfassung:	A solenoid proportional relief valve includes: a joint in which the flow path is disposed; a coil wound to be energized; a needle supported movably along an axial direction of the coil; and a stator generating an attraction force on the needle by excitation of the coil, the needle being formed into a bottomed cylinder having a wall portion and a bottom portion and configured as a biasing member accommodation space accommodating a biasing member in a state where a resilient force is generated in an inner cylindrical portion, an inner surface of the bottom portion being configured as a force receiving section for the biasing member, and the valve body being formed integrally with an outer surface of the bottom portion.
