Abstract: A vehicle seat structure allowing a reduction in the weight of a seat while ensuring cushioning performance. The seat includes a base plate member with an outer frame forming an outer periphery of the seat, and concave portions with seating positions and a seat back position on an inner peripheral side of the outer frame made concave in a direction of a seating load. In addition, the seat includes a fabric member that is provided in a tensioned state in such a manner so as to close open sides of the concave portions for supporting an occupant's weight. A first cushion member is provided in positions on the fabric member, at least corresponding to the outer frame.

Abstract: A vehicle intake duct surrounds a high-flow intake passage, which ensures flow capacity and does not spatially restrict other components. The vehicle includes an engine attached to a vehicle body frame, with the intake duct interconnecting an air cleaner and a throttle body, a transmission for sending engine output to wheels, and a seat mounted on an upper longitudinal frame section of the vehicle body frame. The air cleaner is also provided on the upper longitudinal frame section forward of the seat. The intake duct includes a first extending portion descending rearwardly and downwardly from an outlet of the air cleaner and passing laterally of the throttle body, a curved portion extending rearwardly from the first extending portion and toward a center of the vehicle body frame, and a second extending portion wound around toward a rear portion of the throttle body and connected thereto.

Abstract: The vehicle body frame is configured in a manner that an upper tension pipe is removed from a first cross portion and a second cross portion. When mounting the engine in the vehicle body frame, the vehicle mounted component that is relatively heavy can be lowered into the vehicle body frame from above by removing the upper tension pipe. The vehicle body frame simplifies the removal and installation of the vehicle-mounted components.

The air cleaner apparatus so configured provides a sufficient cooling effect, and is excellent in ease of maintenance.

Abstract: A windshield device for obtaining a favorable screen effect with respect to an air flow from the sides of a screen while suppressing large-sizing of the screen in the vehicle width direction. In a front cowling which includes a screen unit which is mounted on a front portion of a vehicle body and has a screen, an air introducing opening is formed in a front portion of the screen unit and opens forwardly. An air blow-off opening is formed in an upper portion of the screen unit that opens upwardly. An air duct allows the screen unit and the air blow-off opening to communicate with each other. Air discharge ports which open outwardly and to the sides from the vehicle are formed in a side of the air duct.

Abstract: In a windshield unit for a saddle-ride type vehicle provided at the front center of a vehicle body with an air duct for directing the air flow from the front of the vehicle toward the upside, a screen is provided at the front center of a vehicle body with an air duct adapted to lead the air flow from the front of the vehicle toward the upside, a straight portion of the air duct rising in front of an occupant so that a left-right width of a rear wall rearwardly of the straight portion may be narrower than the left-right width of a front wall forward of the straight portion.

Abstract: To make it difficult for the left and right lateral walls of a portion rising in front of an occupant to come into sight through a windshield in a windshield unit for a saddle-ride type vehicle provided at the front center of a vehicle body with an air duct for directing the air flow from the front of the vehicle toward the upside. In a screen provided at the front center of a vehicle body with an air duct adapted to lead the air flow from the front of the vehicle toward the upside, a straight portion of the air duct rising in front of an occupant is provided so that a left-right width of a rear wall rearwardly of the straight portion may be narrower than the left-right width of a front wall forward of the straight portion.

Abstract: A power transmission mechanism of a motorcycle includes a drive case which is disposed at the rear end of and outside of a rear swing arm, and which surrounds the axle of a rear wheel and incorporates a transmission device. In addition, the power transmission mechanism includes a drive shaft extending from an output shaft of an engine for transmitting power of the drive shaft to the rear wheel. The transmission device converts the direction of a driving force of the drive shaft and transmits it to the rear wheel. The drive shaft constituting part of the power transmission mechanism is disposed below the rear swing arm and the pivot shaft. The result is a motorcycle configuration that suppresses the vehicle width without expanding the rear swing arm.

Abstract: A motorcycle with a low floor is configured such that secondary vibration of an engine can be largely reduced and an increase in engine width can be suppressed. The motorcycle with a low floor includes step floors on which to put a rider's feet on left and right sides of a vehicle body frame. An engine is provided between the step floors. A plurality of exhaust pipes extend respectively from cylinders of the engine, the exhaust pipes being gathered at a gathering portion. The engine is an in-line 3-cylinder engine having cylinder portions inclined forwardly. The exhaust pipes extend downwards from the cylinder portions on the basis of each cylinder. The exhaust pipes are bundled and extend on the right side of the engine, in a position on the lower side of one of the step floors.

Abstract: To provide a windscreen apparatus which can provide a good screening effect from traveling wind from the front of a driver while suppressing the height of the screen. The windscreen apparatus includes a front cowl having a screen mounted to a vehicle body. An upwardly opening air outlet port is provided at the center portion of the upper portion of the screen. An air duct for communicating the air outlet port and an air introduction port provided in the front cowl is formed in the screen.

Abstract: The effect of a windshield for a saddle-type vehicle such as a low-slung type of motorcycle or three-wheeled vehicle is enhanced, and pressure is sufficiently adjusted in an open space at the back of the windshield using an inventive windshield system. The vehicle includes a leg shield in front of legs of a rider, and a step space rearward of the leg shield. The windshield system includes a windshield which is provided with an air outlet that opens upward. An air inlet provided at the front of the vehicle communicates with the air outlet other through a duct, and the air outlet opens to the upper center of the windshield. Pressure adjusting outlets, for adjusting pressure in a space around the rider by blowing air toward the step space, are provided separately from the air outlet.

Abstract: A method of loading a two-wheeled vehicle onto a vehicle, e.g., within a trunk space of the accommodating vehicle. The required trunk space can be minimized without relying upon folding of the two-wheeled vehicle. A seat post of the two-wheeled vehicle loaded onto and rearward of a rearmost seat of a four-wheeled vehicle is pulled up forward around a predetermined shaft of pivotal motion. A seat of the two-wheeled vehicle functions integrally as a backrest of a rear seat of the four-wheeled vehicle and a seat back of the two-wheeled vehicle integrally functions as a headrest of the seat of the four-wheeled vehicle.
