Abstract: PURPOSE: A tidal current generator is provided to install a tidal induction plate, which is extended from one side of a guide vane to a direction in which a tidal current flows, inside a duct, thereby preventing the tidal current from being stagnated by the guide vane. CONSTITUTION: A tidal current generator comprises a duct(100), a rotary shaft(200), plural blades(300), and a guide vane(400). The duct forms a water path for the inflow and the outflow of a tidal current. The rotary shaft is installed inside the duct to be vertical to the tidal current direction. The blades are radially installed at the external surface of the rotary shaft, and are rotated by the tidal current which flows inside the duct. The guide vane is formed to protrude inside the duct in order to surround the blades which receive an external force in an opposite direction to the rotary direction by the tidal current which flows inside the duct. A tidal induction plate, extended to a direction in which the tidal current flows and is coupled to the internal surface of the duct, is installed at one end of the guide vane. Two guide vanes are respectively installed at the left and right side of the rotary shaft to be mutually symmetric in a diagonal direction.
