First, the basics will be described. 1 and 2 are perspective views showing the entire embodiment of the present invention. The arrangement of the fin (1) with respect to the leg is different from that of the conventional fin shown in FIG.
The first feature is that the surface is arranged and held perpendicular to the foot plane. In the embodiment, the upper and lower fins are arranged and held because the reaction force received from the water of the fin (1) at the time of beating is balanced by the upper and lower fins of the foot while the fin area is set large, and the fin is applied to the foot plane. The rotational force is offset to zero. It is not always necessary to be both up and down, and the basic function is the same for one side only, but if the fin arrangement is only on the upper side or the lower side of the foot, the opposite rotation will occur when kicking out and pulling back on the foot It takes power and is not preferable.

An embodiment of the third embodiment will be described with reference to FIG. FIG. 1 is a typical example using the rotating fin (1), and the fin rotating shaft (1) is used.
c) and a pair of stoppers (1e) for restricting fin rotation from both sides of the fin are provided perpendicular to the inner surface of the fin frame (2, 3) composed of two plates facing in parallel to each other.
This is an example in which the upper part of the fin is fixed to the fin rotation axis (1c), and the lower part of the fin can rotate around θ = 30 to 60 degrees on both upper and lower sides. The rotary fin (1) shown in the partial cutaway view is an example in which a stopper (1e) is provided at a fin angle at which the propulsion efficiency is good at high speed, that is, at a position around 30 degrees. The beat of the rotating fin (1) is stopped by the stopper (1e).
Until the stopper (1)
After hitting e), the fin angle is maintained at 30 degrees and the operation is performed efficiently. Therefore, it is superior to the example of the fourth aspect to which the conventional fin is applied. It is preferable that the rotating fin (1) is made of a thin elastic material which generates a reaction force by bending the lower end of the fin. The fin frames (2, 3) have two frame plates connected to a rigid body integrally formed with the stopper (1e) support, and are arranged and held in parallel to the legs and perpendicular to the legs, so that the fluttering motion ( The thin line arrow X direction in the figure and the propulsion direction (the thick arrow Y in the figure)
Direction), the cross-sectional area is small and the resistance is small. Also, the two frame plates function to rectify the flow of water and improve efficiency. The thrust works from bottom to top at the fin frame (2, 3) of the shoe part (5).

An embodiment of the fourth embodiment will be described with reference to FIG.
The figure shows an example in which a conventional fin is applied to the present invention. The difference from the third mode is that a conventional fin is applied instead of the rotating fin (1). As can be seen from the figure, the fins (2, 3)
Are arranged vertically above and below the shoe section (5) and perpendicular to the legs and feet.
The root of the upper part of the fin is fixed to the fin fixing part (1f) of the horizontal plate part of the fin frame (2, 3) in which two parallel vertical plates and a plurality of horizontal plates are assembled in a ladder shape. The side and the lower side are made of an elastic material that can be freely bent. Fin frame (2, 3)
Is a flutter foot movement (in the direction of the thin line arrow X in the figure) because the plane cross section is H-shaped and the root of the fin is connected to the side of this H-shape.
And the propulsion direction (the direction of the thick arrow Y in the drawing) has a small cross-sectional area and low resistance. Also, the two frame plates function to rectify the flow of water and improve efficiency. Thrust is third
Works from bottom to top at the positions of the fin frames (2, 3) of the shoe part (5) in the same manner as in the embodiment (1).
