A valve mechanism ( 3 ) includes a valve seat member ( 31 ) having a guiding portion ( 319 ); a valve member ( 32 ) having a valve body ( 321 ), a guiding shaft ( 322 ), and a supporting shaft ( 323 ); and a sub-valve member ( 33 ) having a sub-valve body ( 331 ) and a connecting portion ( 332 ). The valve body ( 321 ) and the sub-valve body ( 331 ) ascend together by pressing the fluid-storing portion ( 11 ); and the valve body ( 321 ) travels to an open position and the sub-valve body ( 331 ) travels to a detached position. In this state, when a pressure applied to the fluid-storing portion ( 11 ) is removed, the valve body ( 321 ) and the sub-valve body ( 331 ) descend together; and after the sub-valve body ( 331 ) travels to a contact position, the valve body ( 321 ) travels to a closed position.
