PROBLEM TO BE SOLVED: To provide a high-performance spiral cave fluid pressurizing and compressing mechanism using a extremely simple means for compactness, energy saving and lower cost. SOLUTION: Spiral caves 4, 6 fixed to a rotating shaft 2 or formed in one unit has spirally rotating motion effects with centrifugal operation, whereby fluid is continuously pressurized to induce pressure in a fixed direction. In the fluid pressurizing and compressing mechanism, the spiral caves gradually change their spiral pitch angles and cross sections to make an accommodation with optional designs adequate for usage purposes.
