部を設けてなる、噴霧器用ポンプ。 A piston is provided with an axial hole inside the piston that communicates with the jet nozzle, and a lateral hole is provided in the radial direction that opens from the jet passage to the outer periphery, and the piston is inserted into the cylinder to seal the space between them. The sealing member is sealed with a member, and the pressing part of the sealing member is pressed against the piston to cut off communication between the horizontal hole and the liquid chamber in the cylinder, and is attached to the inlet of the container, and when the piston is pushed in, The sealing member is elastically deformed by an increase in the liquid pressure in the liquid chamber to separate the pressing part from the piston, and the liquid in the liquid chamber is guided through the side hole to the ejection passage and sprayed from the ejection port, In the pump for an atomizer, when the piston returns, the elastic deformation of the sealing member is restored due to a decrease in the liquid pressure in the liquid chamber, and the pressing part is pressed against the piston again, thereby sucking up the liquid in the container into the cylinder. , the sealing member is provided with a cylindrical portion extending in a direction opposite to the pushing direction of the piston to form a passage between the piston and elastically deforming and expanding in the radial direction due to an increase in liquid pressure in the liquid chamber; . A pump for an atomizer, wherein the pushing part is provided on the tip side of the cylindrical part, and opens and closes the passage to communicate or cut off communication between the liquid chamber and the side hole.
