Fishing device, such as a lure (1), in which there is a body (2), to the front end of which are attached means (3) for attaching a line (4) and at the rear end of which are winglets (11, 12) that rotate due to the force of the water flow. The winglets (11, 12) are mounted eccentrically on bearings on an essentially wire-like axle (9) to rotate in opposite directions and/or at different speeds. The winglets (11, 12) are essentially triangular, the bearing point being essentially at, or in the immediate vicinity of one point of the triangle.
