In the figure, 1 is a plate-shaped floating body, and the figure shows the case of a disk. 2 is a drive shaft passing through the floating body 1 at right angles, 3 is a fin attachment arm fixed to the lower end of the drive shaft 2, and 4 is a fin with its length direction parallel to the floating body 1, and attached to the fin attachment arm 3 as follows. It can be installed as A fin attachment shaft 6 is fitted into the fin head end 4a in the width direction of the fin, and its lower end is pinned to the fin attachment arm 3 by a pin 7 extending in the length direction of the fin 4.
swings at a required angle (approximately 70 degrees) about an axis parallel to the drive shaft 2 using the pin 7 as a fulcrum. 8 is a guide for this rocking motion. At the tip of the fin attachment arm 3, there are stoppers 9 on both left and right sides that limit the rotation angle of the fin 4 about the shaft 6 to a required amount. This stopper 9 may be attached to the head of the fin 4.

な進行方向に向ければよい。 With the above configuration, if the drive shaft 2 is reciprocated by the handle 10 at the upper end of the drive shaft 2, the fin 4 will move as described above with the play of the angle between the two stoppers 9, 9 around the fin mounting shaft 6. Following the reciprocating rotation, the fins 4 fan the water and move the floating body 1 forward. During this reciprocating rotation of the fin 4, the fin 4
uses the pin 7 as a fulcrum and flutters in the direction of rotation of the fin 4 in its width direction, which generates upward pressure and holds down the rear half of the floating body 1, causing the floating body 1 to tilt in the direction of travel so that it rests on the water surface. reduce the resistance of To change the direction of movement, the center line of the reciprocating rotation of the drive shaft 2 may be directed to a new direction of movement.

効果：以上のように本考案の遊泳具は今までに見られ
