In addition, the wave power generator performance evaluation apparatus 100 may include a driving force transmission unit 150 coupled to the shaft 140 and the driving unit 120 to transfer the driving force of the driving unit 120 to the rotating unit 130.

In this case, the driving force transmission unit 150 may be formed in various ways. For example, the driving force transmission unit 150 may be a ring-shaped belt formed of synthetic fibers or rubber. In addition, the driving force transmission unit 150 may be formed of a chain.

On the other hand, the wave generator performance evaluation apparatus 100 includes a link unit 160 that is fastened to the rotating unit 130. The link unit 160 may have a long hole 161 formed to penetrate through one surface thereof. In this case, the insertion protrusion 131 may be inserted into and fastened to the long hole 161.

The wave generator performance evaluation apparatus 100 includes a wave generating unit 170 that is interlocked with the link unit 160 and rotatably coupled to the body unit 110. The wave generator 170 may be formed in a plate shape.

Wave generator 170 may include a flow hole (not shown) formed to penetrate one surface. In addition, the wave generating unit 170 may include a cover (not shown) that is fastened to be rotatable on one surface. In this case, the cover may close the flow hole when the wave generating unit 170 moves in one direction. In addition, the cover may open the flow hole when the wave generating unit 170 moves in the other direction.

Hereinafter, for convenience of description, a case in which one direction is the right side of FIG. 1 and the other direction is the left side of FIG. 1 will be described.
