Zusammenfassung:	PURPOSE:To provide a device for supplying molten magnesium simplifying the assembly and the decomposition and having a simple structure and providing a nonreturn valve automatically opened/closed. CONSTITUTION:The nonreturn valve 40 for communicating/shutting off a molten metal passage is composed of one pair of upper and lower pipe joints 40A, 40R providing a screw part screwing a molten metal supplying pipe 10 at each end parts. Further, a steel ball 40S is incorporated in the inner part and also, a steped part 40M providing a small through-hole in the lower pipe joint (male) 40B is formed, and a stopper 40N for steel ball is arranged on the inner surface of the upper pipe joint (female) 40A.
