摘要: An apparatus for producing fine metal balls comprising a crucible 3 for holding a metal melt and equipped with orifices 2 for ejecting the metal melt; a vibration rod 6 for giving vibration to the melt 1 held in the crucible 3; a vibrator 4 for giving vibration to the vibration rod 6; a means 5 for transmitting the vibration of the vibrator 4 to the vibration rod 6; and a chamber 7 in which melt droplets 9 ejected through the orifices 2 are solidified while dropping, the vibration-transmitting means 5 having one end in contact with the vibrator 4 and the other end abutting a support member 11 connected to the vibration rod 6; the vibration-transmitting means 5 having a cross section decreasing as it nears the support member 11.
