PURPOSE: To provide a liquid suction device by which liquid and air are not sucked simultaneously when the remaining quantity of the liquid inside a liquid vessel becomes small. CONSTITUTION: A liquid suction device is composed of an intermediary member 3 which is installed at an opening part 2 in a liquid vessel 1, a connection pipe 4 which is extended downward from the intermediary member 3 and a weight 6 which is connected to the lower end of the connection pipe 4. The weight 6 has a diameter which is larger than the outside diameter of the connection pipe 4, it comprises a through-hole through which a liquid flows in the interior, and the bottom part of the through hole comprises a bottom-part expansion part 12 the diameter of which is larger than that of the through hole used to make the liquid flow through and which is opened toward the bottom part. |
