PURPOSE: A turbine for tidal current power generation having improved structures of shaft and spoke is provided to reduce the weight through the buoyancy under water and to increase rigidity against the flowing energy of fluid by a spoke which is shaped in multi-layer discs to have a rotary shaft with a sealed hollow and a sealed through-hole. CONSTITUTION: A turbine for tidal current power generation having improved structures of shaft and spoke comprises: a rotary shaft(110), multiple spokes(120), and multiple blades(130). The spokes are connected separately to one another with a predetermined interval according in the longitudinal direction of the rotary shaft. The blades are installed among the spokes to rotate the rotary shaft by the flowing energy of fluid. The rotary shaft forms a hollow part which passes through in a longitudinal direction, and the rotary shaft generates buoyancy under water by sealing the both ends of the hollow part. |
