A partition structure of a greening facility for partitioning a greening area and a non-greening area. Bases (10) are arranged in line near the periphery of a greening area and spaced from each other in the periphery direction of the greening area. A cover (30) is provided over bases (10) spaced from each other to generally cover the upper part and outside part of each base (10). Over the base (10), a space (54) surrounded by the base (10) and cover (30) at the upper part and the outside part and open generally outward from the greening area. A water feed pipe (53) is laid through the space (54) and introduced into the greening area from the portion between the spaced bases (10, 10). Piping and wiring can be easily provided in a partition area laid into the greening area, and members not needing secondary machining and inexpensive can be used for the partition structure.
