The sea wave motor uses energy of sea waves. Drawing 1 shows motor with two axles (1). Disks (2) with teeth (5) are firmly connected with axles (1). Teeth (5) are coupled with teeth (6) of the slides (7) and (8) with guides (10) where the supports (11) and (12) enter. Slides (7) are in connection with light floats (13), and the slides (8) with heavy floats (14). The wave crest lifts light floats (13) with slides (7) and the slides (7) with teeth (6) through teeth (5) rotate disks (2). When wave hollow arrives, the floats (13) with slides (7) drop. This change of direction does not change direction of disk rotation (2), because the teeth (5) and (6) are now in elastic coupling, and as teeth (6) have axles (15) and springs (16). Heavy floats (14) act by force at the wave hollow. By means of coupling the axles (1) accumulation of energy from a larger number of waves takes place.
