Abstract: In a vehicle with a load-carrying platform, an elastic band is provided so a rear portion of a tailgate and a rear portion of a bed extender enter a tensioned state. A rotation regulation mechanism is provided to the tailgate and the bed extender that regulates further rotational movement by the tailgate and the bed extender making contact when the tailgate is rotated towards a closed position. The bed extender and the tailgate are prevented from rotating in the same direction by the rotation regulation mechanism, and the load on the elastic band is mitigated.

Abstract: A front carrier includes an outer frame pipe surrounding the periphery, and a cross pipe and a back-and-forth member which are provided inside the outer frame pipe. A front side portion of the outer frame pipe is lowered at a one-step to form a stepped bottom portion. The back-and-forth member is disposed to extend obliquely downwardly from the cross pipe toward the stepped bottom portion. In addition, the widthwise inside portion of the rear side portion is bent to be forward to form an end side portion, which is joined to the cross pipe to be flush with the back-and-forth member. Thus, a cargo support surface formed by the cross pipe, the back-and-forth member and the end side portion is surrounded by an outer frame portion higher at a one-step than the cargo support. Part of the outer frame portion is allowed to serve as a cargo stopper for the cargo.

Abstract: To provide a swing arm structure capable of suppressing the required rigidity of a cross member to a low level to reduce the weight of the cross member. In a swing arm structure, a swing arm includes a pair of left and right arm bodies with a cross member spanning therebetween. Ends of the swing arm suspend rear wheels. A rear wheel-driving rear drive shaft, connected to a rear final reduction gear unit, is placed above the cross member. As viewed laterally, the cross member is contained within the profile of each arm body and is formed to be trapezoidal in section such that its bottom portion is broader than its upper portion.

Abstract: An improved saddle-ride type vehicle in which heat radiation of a body is improved while the exterior appearance of the body is enhanced, and an exhaust pipe and a muffler are free from interference from the outside while a hose, a cable and the like are designed to be easily retained in place in a simple structure. A saddle-ride type vehicle provides a side cover disposed on the side of a body frame, a foot board disposed below the side cover and an exhaust pipe extending in the forward and rearward direction of a vehicle body disposed inside the body frame. The exhaust pipe is disposed as viewed laterally so as to be exposed to the exterior through an opening surrounded by an upper slat frame, the side cover and the side plate of a foot board, and the guard member is disposed at the opening.

Abstract: A brake caliper support structure and a brake caliper structure for a saddle-ride type all terrain vehicle can attain a reduction in size and weight of a disc brake and can scrape off mud and snow accumulated within a wheel. A distance from a point which represents the center of a front wheel to each of points which represent the axes of bolts located at the same positions as the caliper support portions or the first and second mounting portions of the caliper bracket is set longer than the distance from the point to a point which represents the center of a piston. A brake hose is to be prevented from undergoing an excessively large deflection during steering or during vehicular vibration.

Abstract: A vehicle wheel comprises a rim (172) and a disk section (171) separate from the rim. Since the disk section is separate from the rim, the freedom of designing the disk section is improved. The rim comprises an outer rim (178) and an inner rim (181) separate from the outer rim. The outer and inner rims are attached to the outer periphery of the disk section at the same place by welding.

Abstract: To provide a cooling apparatus for a vehicle enabling protection of a cooling device by effectively utilizing a vehicle frame. The cooling apparatus, which is attached to a vehicle including a vehicle frame and a steering member provided at a front upper portion of the vehicle frame, has a heat exchanger, which performs thermal exchange with the outside air. The heat exchanger is provided within an area formed with a vertical plane passing through a front end of the vehicle frame and a horizontal plane passing through an upper end of the steering member.

Abstract: An extension portion extending outwardly is integrally formed on the edge of an end portion of an exhaust pipe; a collar is fixed on the outer periphery of the end portion of the exhaust pipe by caulking; and the edge of the outer end of the collar is abutted against the extension portion. The aforementioned arrangement provides a connection portion of an exhaust pipe for an engine which is intended to rigidly connect the exhaust pipe to an exhaust port of the engine, to prevent gas leakage by eliminating the occurrence of clearance at the connecting portion, to reduce the flow resistance of exhaust gas in the exhaust pipe, and to reduce the production cost of the connection portion.

Abstract: A mounting structure of an exhaust pipe system in a vehicle capable of making a magnitude of a moment acting on the exhaust pipe system as small as possible by means of a simple constitution. In a mounting structure of an exhaust pipe system in a vehicle the exhaust pipe system is connected to an engine loaded onto the vehicle and for guiding exhaust gas discharged from the engine to the ambient air, on a vehicle body frame constituting the vehicle, wherein the exhaust pipe system is constituted so as to be connected to the vehicle body frame in a position substantially upwardly from a position G of the center of gravity of the exhaust pipe system.
