PROBLEM TO BE SOLVED: To generate force in a gravity direction equivalent to buoyancy without canceling the buoyancy and thus improve efficiency and a utilization factor in a wave power engine using a float, in contrast to low conversion efficiency and a low utilization factor of a back-end device due to limited utilization of only motion pushing the float upward. SOLUTION: The float device has two sections fixed in the top and bottom to form a structure capable of producing both buoyancy and force in a gravity direction. The top section is filled with a filler of small specific gravity. The bottom section is filled with a filler of specific gravity approximate to that of a setting location of the float device so that the bottom section does not cancel buoyancy when underwater and generates force in a gravity direction when the float device is lifted above an equilibrium position with the water surface. When the float is lifted and lowered from the equilibrium position with the water surface, force toward the equilibrium position is generated.
