PROBLEM TO BE SOLVED: To provide a liquid supplying mechanism which can equally supply liquid to plants on each stage arranged in multi-stage without controlling flow by a valve.SOLUTION: A liquid supplying mechanism (20) comprises a liquid supplying pipe (30) that supplies liquid by natural fall to the plant arranged on a shelf part (16) of a multi-stage. The liquid supplying pipe (30) has a plurality of drip infusion tubes (31) and a plurality of liquid sending tubes (33) linked with each drip infusion tube (31). A liquid stream entrance (34) of the liquid sending tube (33) that sends liquid to the drip infusion tube (31) of the lower stage side is provided upward from a drip infusion mouth (32) of the drip infusion tube (31) of the upper stage side.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】バルブによる流量調整を行うことなく、多段に配された各段の植物に均一に液体を供給することができる給液機構を提供する。【解決手段】給液機構(20)は、複数段の棚部(16)に配された植物に自然落下により液体を供給する給液管(30)を備えている。給液管(30)は、複数の点滴管(31)と、各点滴管(31)に連結された複数の送液管(33)とを有し、下段側の点滴管(31)に液体を送る送液管(33)の液体流入口(34)が、上段側の点滴管(31)の点滴口(32)よりも上方に設けられている。【選択図】図1
