PROBLEM TO BE SOLVED: To provide an LP gas filling valve allowing simplifying an inner structure of the valve for miniaturizing it as well as providing interchangeability with the other LP gas filling valve by simplifying a mounting structure of an LP gas cylinder attaching port for facilitating replacing works. SOLUTION: Inside an LP gas filling passage 5 downward from an opening/ closing valve 6, a first annular passage 15 for filling LP gas is formed on an outer circumference of a hollow pipe with a smaller diameter than an inside diameter of the passage 5 and a gate valve 14 for opening/closing an opening of a hollow pipe head part 13a is mounted at an upper end. A second annular passage 16 for supplying LP gas inside an LP gas cylinder 1 to an LP gas using equipment supplying port 25a side is formed on an outer circumference of a valve rod 12 locking a float 9 at a lower end inserted into the hollow pipe 13 and facing inside the LP gas cylinder 1. Accordingly the inner structure of the LP gas filling valve 2 is simplified for enabling miniaturizing it and the mounting structure of a mounting part 11 to be attached to the attaching port of the cylinder 1 is simplified for facilitating replacing works.
