PURPOSE:To increase generating capacity in comparison with the size of a buoyant body by a method wherein the inner diameter of the buoyant body for a piston chamber is made larger than the same of a tail tube in the buoy generating electricity by wave power in which the air piston chamber, opening the lower surface thereof into water, is attached to the buoyant body. CONSTITUTION:The air piston chamber 1, opening the lower surface thereof into water, is attached to the buoyant body 2 and an air turbine generator 3 is provided above the air piston chamber. The air piston chamber 1 is formed so that the inner diameter D1 of a part 1', engaging with the buoyant body 2, is larger than the inner diameter D2 of the tail tube 1'', therefore, the weight of sea water column in the air piston chamber 1 is reduced compared with a conventional air piston chamber type having a constant inner diameter and thereby enabling to reduce the submerged area of the buoyant body and decrease the weight of the same.
