Abstract

A water vehicle is provided. The water vehicle comprises: buoyant bodies (10) arranged parallel to and spaced a certain distance from each other; a general bicycle (20) fixedly mounted on a space between the buoyant bodies (10); a front support (30) connecting a front end of a main frame (23) of the bicycle (20) and the buoyant bodies (10) to support the bicycle (20); a rear support (40) connecting a rear end of the main frame (23) and the buoyant bodies (10) to support the bicycle (20); and a propulsion part (50) including a propeller body (52) connected to an auxiliary sprocket (27) of the bicycle (20) such that the rotation of a rear wheel (22) and sprockets of the bicycle (20) in conjunction with the rotation of pedals (24) of the bicycle (20) drives a propeller (52) of the propeller body (52). The auxiliary sprocket (27) is integrated with a rotary shaft (27a) penetrating the center of the auxiliary sprocket (27), the rotary shaft (27a) penetrates a bracket (26a) of the bicycle (20), both end portions of the rotary shaft (27a) divided by the bracket (26a) are rotatably supported by respective bearings (26b), and a power transmission cable (51) is connected to the rotary shaft (27a) of the auxiliary sprocket (27) and the propeller (52a) of the propulsion part (52) to transmit a rotational force of the auxiliary sprocket (27) to the propeller (52a). In the water vehicle, the rotary shaft of the auxiliary sprocket for gear shift positioned adjacent to the rear wheel is rotated integrally with the auxiliary sprocket and the power transmission cable is connected to the rotary shaft to rotate the propeller, so that a power can be transmitted to the propeller without any friction, thus enabling rotation of the propeller with a small force to cause no difficulty in transmitting the power to the propeller for a long time. In addition, the water vehicle uses the rotational force of the auxiliary sprocket, whose diameter is much smaller than that of a driven sprocket, to obtain a relatively high rotational speed of the propeller, resulting in a greatly increased propulsive force of the propeller.
