摘要： A light and relatively simple structure for preventing rain leakage in a tree house. A tree house using a trunk of a tree as a pillar inevitably has a gap between the trunk and a roof. Thus, a plurality of two-layer waterproof sheets are placed on top of the roof, so that each sheet can absorb rain water that would run down the trunk of the tree and enter the gap, and can drain the rain water onto the roof. This makes it possible to prevent rain leakage in the tree house through the gap between the trunk of the tree and the roof.
