SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems of the prior art, and comprises a method of floating a boat and injecting a jet from a plurality of discharge nozzles arranged in an extending direction. A water flow is generated, and in the annular waterway in which the boat is moved by the water flow, an oscillating section is formed in a part of the annular waterway, and in the oscillating section in the direction of jet of the jet of the discharge nozzle. In order to provide a swinging device for a game boat in an annular waterway in which a swing nozzle for ejecting a jet in an opposing direction is arranged, and a jet is temporarily ejected from the swing nozzle to swing the boat. Is what you do.

[0007] It is preferable that the jet jetting from the oscillating nozzle is intermittently performed. Further, the discharge nozzle and the oscillating nozzle are arranged at either the bottom or the side wall of the annular water channel, and it is preferable to arrange two or more as needed. Further, it is preferable that the oscillating nozzle is configured to be rotatable in the horizontal direction and to be able to descend. It is preferable to arrange a boat position detector at least on the upstream side in the swing section, and to control the ejection of the jet from the discharge nozzle and the swing nozzle by a signal from the position detector.

In the swinging device for a game boat in the annular waterway configured as described above, when the boat reaches the swinging section, a jet is jetted from the swinging nozzle temporarily or intermittently. Since this jet is made to oppose (or oppose) the direction of the water flow, the water flows in different directions collide with each other and generate a large wave. Since the boat is located within the range where the waves are generated, the boat can be rocked violently.

Further, when the jet is directly applied to the front of the boat, the swing of the boat can be further increased. Further, if the waves are controlled so as to be synchronized with the natural frequency of the boat, the boat can be rocked effectively with less energy. The timing, interval, direction, and jetting force of the jet from the oscillating nozzle are appropriately selected in accordance with the size and weight of the boat, the number of passengers, the content of the performance, and the like. By changing the pitch and rolling cycle and size, it is possible to effectively give the occupant a sense of realism.
