The holding area 13 is formed by being surrounded by a bottom surface 101 and a side surface 102 of the inner layer planter 10, a submerged hole 141 is formed on the holding area 13, and the submerged hole 141 and the space area 12 are communicated to each other. The submerged member 2 is made of a plurality of particles 20 and 20', a minute flow path 21 is formed between the particles 20 and 20', and the submerged member 2 is installed on a water current path from the holding area 13 to the submerged hole 141. <P>COPYRIGHT: (C)2012,JPO&INPIT |
