A fuel tank of a motorcycle is disposed between a head pipe and a rider's seat. A cylindrical body forming a filler port is disposed at an upper portion of a tank main body of the fuel tank. A first mounting portion is formed on an outer peripheral surface of the cylindrical body projecting from the upper portion of the tank main body. A tank upper portion cover is mounted on the first mounting portion so as to cover an upper portion of the fuel tank.

This rear wheel suspension device of a motorcycle is disposed so as to be displaced to the right lateral side relative to a center portion in the vehicle widthwise direction of the motorcycle. A swingarm-side support member which extends in the vehicle widthwise direction is provided to a swingarm. An upper end portion of the rear wheel suspension device is rotatably supported by a main frame, and a lower end portion of the rear wheel suspension device is rotatably supported at a right end portion of the swingarm-side support member.

This rear wheel suspension device of a motorcycle is disposed so as to be displaced to one lateral side relative to a center portion in the vehicle widthwise direction of the motorcycle. A main frame which forms the front half of a motorcycle frame structure has a single backbone frame extending from a head pipe rearward and obliquely downward in the center portion in the vehicle widthwise direction. A vehicle-body-side support member which extends in the vehicle widthwise direction is supported by a rear portion of the backbone frame. A one end portion of the rear wheel suspension device is rotatably supported by a right end portion of the vehicle-body-side support member.

A small boat comprising a helmseat positioned at the center of the forward half of the boat, and a control stick for steering the boat positioned at the front of this helmseat. Since the helmseat is positioned at the center of the forward half of the boat, the driver is located approximately equidistant from the left and right gunwales, which makes it easier to steer the boat. In addition, a control stick is positioned to the front of the helmseat, and, because this control stick can be used to steer the boat and also to change the direction of the boat, the amount of space required to steer the boat is less than that required in a design wherein steering is performed by turning a circular steering wheel, such as with the prior art already described. This is effective particularly for a small boat moving at a high speed.
