<P>PROBLEM TO BE SOLVED: To solve the problem of coping with rotation disturbance of a hydraulic turbine due to flow-in of floatages and the like and the problem of coping with a reverse flow phenomenon of tidal current due to passage of time, avoid influence of pulsation of the hydraulic turbine without using a chain or the like that involves large torque transmission loss, and satisfactorily generate electric power, in a tidal current power generating device. Ž<P>SOLUTION: This device includes the hydraulic turbine including a rotary shaft perpendicular to water current and water surface, and a plate shape water introduction member which is a plate shape member capable of rotating in a limited range with one end part used as a rotary shaft and effectively introducing water even to reverse flow phenomenon of tidal current for introducing flowing water to a zone at a side contributing torque of the hydraulic turbine. The hydraulic turbine and the plate shape water introduction member are arranged symmetrically with respect to a line at a plane center part of a device and forming a pair. The device includes a string shape screen section having a square tube shape section surrounding the pair of the hydraulic turbine and the plate shape water introduction member and a plate shape long member for preventing floatage from flowing therein at both opening parts of the square tube shape section arranged in parallel with angles to water flow. Gears are used for transmission mechanism of torque of the hydraulic turbine. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
