<P>PROBLEM TO BE SOLVED: To provide a propeller that can be steered in relation to a behavior such as a lateral weight movement or the like in steering the hull and can be turned in the tilting direction of the hull by the weight movement without operation or the like of a steering bar or the like of a driver, when the propeller is detachably attached to the hull such as a surfboard and the steering of controlling the propelling direction by the propeller in propelling by the propeller. <P>SOLUTION: The propeller 1 is detachably attached to a waterborne vehicle via a attaching mechanism 10. The propeller 1 comprises a body 2 to be attached to the hull 60 by the attaching mechanism, and an attaching section 11 that is rockably connected to the body via a shaft 12 directing in the longitudinal direction and has a substantially vertical surface for attaching a propelling device 50 steerable by the vertical shaft. A converting mechanism 30 for performing the conversion so that a steering motion of the propelling device in relation to the tilting by lateral tilting of the waterborne vehicle with respect to the water surface is interposed between the attaching section and the body. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
