NOVELTY - The apparatus has an actuating mechanism (8) that is configured to convert the power of the circumferential speed of a reciprocating panel (2) at a distance point being situated at the area of the upper half of the panel mechanically to a rotational movement of the rotor of the generator of a power-take-off machinery (11). The distance point is situated at the area of the upper fourth and third or half of the panel. The distance point acts as a power take-of point that is separated from the supporting point of the panel.    USE - Wave energy conversion apparatus used in connection with panel or flap or essentially plate like wing element hinged with its lower edge to make reciprocating movement caused by wave energy or tidal energy of seawater.    ADVANTAGE - The wave energy conversion apparatus is obtained with reliable, compact, economical and efficient manner and able to capture a maximum amount of available wave energy. The installation and maintenance of the wave energy conversion apparatus is made easy and fast. The apparatus is easy to transport to the installation site. The power to weight ratio of the wave energy conversion apparatus is much bigger so that the coefficient of efficiency improves and the structure of the apparatus is smaller and simpler, which makes the apparatus more inexpensive to manufacture. The robust hydraulic arrangements are no more needed because dominant greater forces and torques are not focused to the power conversion unit. Thus makes the lifetime of the apparatus and also maintenance intervals longer. Easily available and relatively inexpensive commercial components are used in many places of the apparatus. Small and lightweight structure are obtained thus it is easy to be assembled in its installation site without big machines and cranes.
