<p>The present invention relates to a tidal current generator capable of maximizing the amount of tidal power generation in a low speed tide by maximizing a contact area with a tide and reducing air resistance above water. According to the present invention, the tidal current generator comprises: a basic structure (a support body, a buoyancy body, or the like) supported on the sea or supported by the sea bed floor; a rotor (20) installed to be immersed in water through the basic structure, and rotated by a tide; an in-out type blade (30) to minimize resistance as being inserted not to protrude from the rotor, and rotating toward a surface opposite to a tide direction while being rotated by the tide as being protruding under water and installed in the rotor to appear and disappear; and at least one generator (40) connected with a rotary shaft of the rotor to generate electric energy by receiving a rotational force.</p> |
