Abstract: The present invention relates to an air cleaner element holding structure for an air cleaner device for use in filtering intake air for an engine. The air cleaner device includes an air cleaner element and an element holder, provided in an air cleaner case. The air cleaner element includes at least a pair of element support plates and the element holder includes at least a pair of circular plates. The air cleaner case includes an intake duct facing an inner circumferential side of the air cleaner element for conducting air thereto. Each of the support plates has an outer diameter that is larger than that of the air cleaner element. The element support plates support the air cleaner element in such a manner that both ends, in the axial direction, of the element holder contact an inside surface, in the axial direction, of the element support plates.

Abstract: An air cleaner is disposed on an upper side of an engine. The air cleaner and an intake port of the engine can be easily connected without enlarging the interval between a left-right pair of frames. A saddle ride type vehicle includes a longitudinally laid crankshaft type engine having a crankcase, a cylinder and a cylinder head. A left-right pair of frames support the engine. An air cleaner is disposed on the upper side relative to the engine with the frames therebetween. The air cleaner takes air in through an intake duct connected to the engine through a throttle body provided in a case. The engine is disposed so that the cylinder is inclined to one side and the one side of the cylinder head is disposed near one of the frames. The throttle body is disposed between the other frame and the other side of the cylinder head.

Abstract: An engine arrangement structure of a saddle-ride type vehicle includes an engine having a crankcase and a cylinder part overhung upwardly from the crankcase. An alternating current generator is provided at one end of the crankshaft with a power transmission system member being provided at the other end thereof. The alternating current generator and the power transmission system member are overhung ahead of and behind the engine relative to the engine cylinder part, respectively. A width by which the power transmission system member is overhung is larger than that by which the alternating current generator is overhung. The alternating current generator of the engine is arranged so as to be directed to the front side of the vehicle body and the power transmission system member is arranged so as to be directed to the rear side of the vehicle body.

Abstract: A drive switching lever device for a vehicle for a vehicle in which a single control lever can operate both two-wheel-drive/four-wheel drive switching means and a differential lock on/off switching mechanism includes a bell crank swingably supported by a vehicle body side. A pull rod adapted to operate a switching lever of a two-wheel-drive/four-wheel-drive switching means is connected to a lever bracket and a control cable adapted to operate a switching lever of a differential lock on/off switching mechanism is connected to the bell crank. When a control lever is swung independently of the lever bracket, the bell crank is swung in engagement with the shaft portion of the control lever. The resulting configuration provides flexibility for the layout of the linkage between the control lever and the operating portion of each switching mechanism.

Abstract: A refueling operation of an all terrain vehicle can be enhanced, even when a fuel tank is arranged below a seat, without changing an entire length of the vehicle. A fuel tank is arranged below a seat. A seat concave portion with a substantially concave shape when viewed from the top is formed in the seat. A fuel filler of the fuel tank is arranged in the seat concave portion to be seen from the top. It becomes possible to perform refueling from the fuel filler without detaching the seat. Also, an overlap between the seat and the fuel filler when viewed from above is avoided, with a reduction in a seating area of the seat minimized.

Abstract: A frame structure and a method of manufacturing a body frame that is divided into small assemblies to facilitate the carriage and storage of articles and individuals and the manufacturing efficiency. A body frame is divided into three, namely, a front assembly having a closed loop structure, an engine support system assembly having a closed loop structure and a rear suspension support system assembly having a closed loop structure. The front assembly and the rear suspension support system assembly are connected to the engine support system assembly to form the body frame. The small assemblies have a closed loop structure whereby the rigidity is enhanced, and the shape is also stabilized. Therefore, the accuracy management can be performed.

Abstract: A running board for an all-terrain vehicle includes structure for substantially blocking snow, mud and the like from landing onto the running board during operation, and also for blocking engine heat from excessively warming the feet of a rider. In a running board including a step portion which is positioned on a side of a powertrain unit having an operation pedal in a side portion thereof, a partition is provided between the engine and the step portion, the partition including an insertion opening portion into which the operation pedal is inserted. The partition can be made wider since the operation pedal is inserted into the insertion opening portion blocking snow, mud and the like from coming through a space between the running board and the engine. The partition plate also tends to block engine heat from excessively warming the feet of a rider.
