PURPOSE:To obtain high energy converting efficiency by providing at least two chambers in the direction of arriving wave and providing a shatter for opening and closing a duct in a connecting part to an air duct of a chamber positioned backward with respect to arriving wave. CONSTITUTION:In a first chamber 31, an air turbine 71 and a generator 81 are provided in a first duct 61 which is connected to a second opening part 51 and a first opening part 41 which is faced to arriving wave. On the other hand, a shatter 12 is provided on a second opening part 52, to open and close a duct 62. Thereby, when the wave length of wave is shorter, the shatter is closed to make the chamber function as one having a depth of smaller dimension, enabling an air turbine to rotate efficiently. |
