<p>The present invention relates to paddles operated by feet which progress a boat, a kayak, and a canoe when the symmetric paddles are operated by the feet in turn. The present invention turns to the left when operating the paddle by a right foot and turns to the right when operating the paddle by a left foot. The paddles comprise: a driving force portion; a combining portion; and a fixed portion. The driving force portion has the moving paddles in lower portions of rods where the paddles, to be stepped by the feet, are attached in a symmetrical structure, and two fixing rings, restricting the operation of the paddles, are attached to the rods in upper and lower portions of the paddles. Rotary shafts, attached to the rods, are symmetrically formed to reciprocally move back and forth by being combined with rotation supporting portions of a combining plate. The combining portion is made to reciprocally move back and forth since the rotary shafts of the driving force are connected to the rotation support portions of the combining plate, and is made to fix the combining plate with fixing screws. The present invention includes the fixed portion which fixes a fixed plate (9), installed around a hole formed in the center of the boat, the kayak, and the canoe, and the fixing screws to fix the combining portion.</p> |
