Beschreibung
Zusammenfassung:	A fluid control valve unit includes: a fluid control valve including a sleeve in a bottomed cylindrical shape defining an axis, and a spool slidably accommodated in the sleeve in a direction of the axis; a cylindrical passage member including an inner peripheral surface to which the sleeve is fitted, a receiving part for receiving an end of the sleeve in the direction of the axis, and an annular groove recessed from the inner peripheral surface; and a snap ring including a notch with a predetermined gap and fitted in the annular groove to be capable of restricting the fluid control valve accommodated in the passage member from falling off in the direction of the axis and to be capable of discharging fluid flowing through a discharge passage formed in the passage member.
