PURPOSE: An artificial tree is provided to selectively provide fluid pressure to the inside of leaves or petals, thereby variously changing the shape of the artificial trees. CONSTITUTION: An artificial tree(10) comprises an artificial trunk part(110) and an expandable part(120). A fluid pipe(111) is formed inside the artificial trunk part. The expandable part is combined with the artificial trunk part and has a hollow part(121) which is connected to the fluid pipe. The artificial tree additionally includes an artificial branch part between the artificial truck part and the expandable part. A supplemental fluid pipe is formed on the artificial branch part. The expandable part is formed with a flexible material. The expandable part is a leaf and/or a petal shape. The artificial tree additionally includes a control part(140). The control part controls the flow rate of the fluid inside a stream tube. |
