Abstract
An object of the present invention is to provide a natural energy extraction apparatus comprising a vertical rotating shaft and a float for supporting the vertical rotating shaft, wherein the internal structure of the float is simpler, the float and a mooring apparatus are more compact, and production cost is lower than in the conventional natural energy extraction apparatus. A natural energy extraction apparatus comprises a first float forming a swingable vertical rotating shaft, a second float moored to surround the first float, and a power transmission device attached to the second float to convert rotational kinetic energy of the first float to driving torque for driven equipment, and the natural energy extraction apparatus is installed on a body of water.

A natural energy extraction apparatus comprising:
- a first float forming a swingable vertical rotating shaft, a second float moored to surround the first float, and a power transmission device attached to the second float to convert rotational kinetic energy of the first float to driving torque for driven equipment, wherein the natural energy extraction apparatus is installed on a body of water,
- wherein the power transmission device comprises a plurality of sets of toroidal rollers, disposed to retain contact with the swingable cylindrical rotating shaft as the rotating shaft swings, and a support member supporting each set of rollers and circumferentially distanced from one another, and
- wherein each roller contacts the circumferential side surface of the first float at circumferential side surface and the support member is attached to the second float so as to support each roller rotatably around three axes orthogonally intersecting to one another and resiliently force the roller on the circumferential side surface of the first float.
