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.
