Abstract: A method of producing an undercover for a vehicle includes: placing a first component including a planar surface, second components including planar surfaces, and a third component including a cavity with an opening in a surface such that the third component is sandwiched between the second components with the surfaces of the second components and the surface of the third components opposed to the surface of the first component; placing the sheet that is softened between the first component and the second components; vacuuming the sheet with the first component until a first surface thereof is pressed against the surface of the first component; bringing the surfaces of the second components into contact with a second surface of the sheet; and moving the third component toward the first component until the cavity is filled with a portion of the sheet while maintaining the first component and the second components thereat.

Abstract: A vehicular undercover constituting a lower surface of a vehicle and molded from a synthetic resin sheet includes a cover main body having a plate shape including one surface that is a flat surface and another surface that is opposite to the one surface, a reinforcing rib projecting from the other surface of the cover main body, and at least two auxiliary ribs projecting form the other surface of the cover main body and sandwiching the reinforcing rib therebetween. The cover main body includes a first portion and a second portion. The first portion is between the at least two auxiliary ribs and has a first thickness, and the second portion is on an opposite side to the first portion with respect to each of the at least two auxiliary ribs and has a second thickness. The first thickness is smaller than the second thickness.

Abstract: Structures of a supporting mechanism for a power source in a vehicle can include a seat portion and a fixing portion. The seat portion can be attached to a body of the vehicle. The fixing portion can extend from the seat portion. One or more stackable power sources can be accommodated within and secured by the fixing portion. The power source supporting mechanism can be easily mounted in available space in or on or otherwise associated with the vehicle, enabling the power source supporting mechanism to be readily adaptable to various different kinds of vehicles. The vehicles may be motorcycles, for example.

Abstract: A vehicle shroud can include a front projection, a middle projection and a rear projection. In a side view of the vehicle shroud, the front projection can be approximately wedge-shaped, and the middle projection can extend downward.

Abstract: A vehicle shroud can include a frontward portion, an intermediate portion, and a rearward portion. The vehicle shroud can have formed therein at least one opening extending in a substantially front-to-rear direction. A substantially horizontal portion of a front fender of the vehicle can be located frontward of, and be substantially aligned with, the opening. The vehicle can be a motorcycle, for example.

Abstract: According to some embodiments, a motorcycle includes a vehicle body frame 20, an engine 3 mounted on the vehicle body frame, a fuel tank 4 disposed above the engine, a radiator 5 disposed in front of the engine, and an intake device 6 connected to the engine. The intake device 6 has an intake opening 30d, and an intake passage 31 which connects the intake opening in fluid communication with a front portion of the engine. The intake passage 31 is disposed between the fuel tank 4 and the radiator 5 as viewed from a side of the motorcycle.

Abstract: A spring spacer is provided to improve the durability of a spring, which is made of Ti or the like and low in surface hardness, by preventing abrasion With the spring spacer placed between a first turn and a second turn of a Ti spring, the spring spacer prevents an end of the first turn from contacting the second turn. The spring spacer includes a contact preventive portion that is interposed between the first turn and the second turn of the Ti spring to prevent the end of the first turn from contacting with the second turn. A holding portion holds the contact preventive portion on the spring or the spring bearing surface. The spring spacer can be used in a variety of applications, including on vehicle suspension springs, engine valve spring, and similar lightweight springs.
