Abstract
A liquid filling nozzle including: a tubular nozzle main body having a liquid supply opening and a liquid discharge port, a center rod disposed inside the nozzle main body and raised and lowered, and an opening-and-closing valve body which opens the liquid discharge port when the center rod is lowered and closes the liquid discharge port when the center rod is raised. A throttle valve mechanism formed by a throttle valve seat, which is disposed on the inside wall surface of the nozzle main body, and a throttle valve body, which is disposed on the center rod, is provided in the filling nozzle so that the throttle valve mechanism opens when the center rod is lowered, and, when the center rod is raised, the throttle valve mechanism closes before the opening-and-closing valve body closes off the liquid discharge port, thus constricting the flow path for a liquid.
