PROBLEM TO BE SOLVED: To reduce count of parts of a content discharge mechanism by forming a valve of the accumulator content discharge mechanism discharging content based on valve action of reciprocating motion of a movable member on a part of the movable member and an outlet member. SOLUTION: A slit 6c formed at boundary part of a pillar shape part 6a of the movable member 6 and a skirt part 6b is used as an upper stream side valve of a reservoir part 4. A cross shape cut part 11a formed on the outlet member 11 is used as a lower stream valve. In a stationary mode, the movable member 6 moves up, the cross shape cut part 11a closes and content does not leak to outside. In an operating mode in which the movable member 6 moves down, since pressure in the reservoir part 4 rises, the slit 6c closes, the cross shape cut part 11a opens and content of the reservoir part 4 is discharged to an external space. When the movable member 6 returns to the stationary mode, since pressure in the reservoir part 4 drops, the cross shape cut part 11a closes, the slit 6c opens and content in a storage part 3 flows in the reservoir part 4.
