摘要： The present invention provides a watercraft having steering components (steering tabs or stabilizers) for maintaining steering capability even while amount of water ejected from a propulsion pump is decreased. The steering components are movably disposed on a hull of the watercraft at or below the water level on both right and left sides to be in an “Operating State” in which resistance of water is larger or to be in a “Non-operating State” in which the resistance of water is smaller in accordance with steering operation. Furthermore, a mechanism for absorbing an external force acting on the steering components in the “Operating State” is located in a system for operating the steering components. The mechanism reacts to the external force to allow the steering components to be transformed into the “Non-operating State.”

摘要： Provided is a hull shape of a personal watercraft which can enhance speed performance, and still more, can also reduce rolling of a body. A bulging face 12 is formed on an outside part of a rear portion of a hull bottom 20 having a substantially V-shaped cross section and protrudes downward from an outside front face 20a positioned in front of the outside part. The bulging face 12 includes a fore part 13 inclined downward in the rearward direction, and a rear part 14 positioned above a virtual face A extended rearwardly from the fore part 13.

摘要： A bottom structure of a personal watercraft enhances the running performance of a personal watercraft. A concavo-convex face (21) having very small concave or convex portions for drawing air from an outside of a watercraft is formed on a water contact face (S) in a bottom surface (20) of the personal watercraft during planing. The air is drawn by the concavo-convex face (21), thereby separating a water flow from the bottom surface (20). Consequently, frictional resistance to the water in the bottom surface (20) can be reduced.
摘要翻译： 个人船只的底部结构增强了个人船只的运行性能。 在刨削期间，在个人船舶的底面（20）中的水接触面（S）上形成有用于从船舶外部抽出空气的非常小的凹凸部的凹凸面（21）。 空气由凹凸面（21）拉出，从而将水流从底面（20）分离。 因此，可以减小对底面（20）中的水的摩擦阻力。

摘要： An inner frame member, of a length that is less than the entire length of a hull, is joined to the inner surface of the hull that forms a lower portion of a body of a personal watercraft. The inner frame member has an engine mount portion that supports an engine thereon, an impeller shaft support region that supports thereon an impeller shaft of a propulsion device driven by the engine, and bulkheads extending in the lateral direction of the hull and joined to the inner surface of the hull. In accordance with the present invention, the personal watercraft is light weight, but also retains rigidity and assembling efficiency of the hull.

摘要： A body frame of a two-wheeled vehicle. The body frame typically includes a head pipe to which a steering shaft extending substantially vertically is rotatably mounted. The head pipe includes an upper head pipe and a lower head pipe that are configured to be molded and to be coupled to each other. The upper head pipe includes an upper tubular portion into which the steering shaft is inserted and a main frame tongue portion that is configured to extend rearward from the upper tubular portion and is configured to support a front portion of the main frame from above. The lower head pipe includes a lower tubular portion into which the steering shaft is inserted and a down tube tongue portion that is configured to extend downward from the lower tubular portion and to support an upper portion of the down tube from forward.
