PROBLEM TO BE SOLVED: To provide an umbrella type spiral water turbine capable of efficiently obtaining rotational force from flowing water in the whole water turbine while installed in a vertical manner and compactifying its installation area.SOLUTION: An umbrella type spiral water turbine includes a conical rotational trunk 11, and a plurality of rotational blades 12 provided into a spiral shape on the outer peripheral surface of the rotational trunk 11. The rotational blades 12 erect from the outer peripheral surface of the rotational trunk 11 toward upward, and a distance between adjacent rotational blades 12 are made larger from the upper part of the rotational trunk 11 to the lower part thereof. The water turbine installs a rotational shaft in a vertical manner so as to face the apex of the rotational trunk 11 upward, and receives flowing water pressure falling from upward to rotate. 【課題】縦向きに設置して設置面積をコンパクト化しながら、水車全体において流水から効率良く回転力を得られる、傘型螺旋水車を提供する。【解決手段】円錐形の回転胴１１と、該回転胴１１の外周面へ螺旋状に設けられた複数枚の回転羽根１２とを有する。回転羽根１２は、回転胴１１の外周面から上方へ向けて立設しており、回転胴１１の上部から下部にかけて隣り合う回転羽根１２間の距離が拡がっている。回転胴１１の頂部を上方にして回転軸を縦向きに設置し、上方から落下してくる流水圧を受けて回転する。【選択図】図２
