Zusammenfassung:	PROBLEM TO BE SOLVED: To provide good positioning of a needle to prevent liquid from penetrating into an air passage. SOLUTION: A valve seat member is connected with a body, and a needle 16 is mounted in the body movably to the valve seat member 14. First and second needle guiding elements 18, 20 connected with each other accommodate respective parts of the needle so as to prohibit transverse movement of the needle 16. The first needle guiding element 18, when the needle 16 is moved so as to separate from a valve seat, allows liquid to flow to a delivery orifice 15 through a liquid passage 22 adjacent to the first needle guiding element 18. The first needle guiding element 18 is connected with the valve seat by press-in, and is connected with the second needle guiding element 20 by another press-in. These both interconnected needle guiding elements 18, 20 are similarly pressed into a hole of the body. In addition, a liquid seal is arranged between the first and second needle guiding elements 18, 20.
