The present invention comprises the following: a rainwater storage tank (10) for storing rainwater; a drop discharging member (30) discharging the rainwater stored inside the rainwater storage tank in a water drop form; and a storage box (40) storing the rainwater storage tank (10) and the drop discharging member (30), collecting the rain water discharged from the drop discharging member (30), and discharging the collected rainwater while widely spreading the rainwater to the outside. The rainwater storage tank (10) comprises the following: a storage space (11) for storing the rainwater; a side draining hole (13) formed on the side surface for draining the rainwater inserted into the storage space (11); a washing water inlet (14) supplying washing water from the outside by being installed on one side of the storage space; an over-flow pipe (15) formed on the other upper side of the storage space for discharging the rainwater from the storage space to the outside when the storage space is full; and a drain pipe (16) formed on the other lower side of the storage space for discharging the rainwater or the washing water to the outside. |
