PROBLEM TO BE SOLVED: To make a wave generating area in front of a wave generating plate wide while making a constitution of the wave generating machine compact. SOLUTION: The wave generating machine 10 is composed of a plurality of wave generating plates 11, each lower end of which is swingingly supported by a frame 13 with a hinge 14 at the bottom of the test cistern 12. The upper end of each wave generating plate is connected with a reciprocating slider 16 reciprocating in a wave generation direction 15 via a driving motor 20, a ball screw 19, and a slider guide 21. Wherein, the plurality of wave generating plates 11 are arranged under the reciprocating path of the reciprocating slider 16 for down sizing this machine. The connecting means is a ball spline 17 which contributes to down sizing, to absorbing a positional deviation of the connecting part in the vertical direction caused by the circular motion, and to generating a precise waveform, and also contributes to making the swinging range of the wave generating plate perfectly be within the running range of the reciprocating slider.
