A straddled vehicle including a frame structure having a frame body, a rear arm swingably supported by the frame structure, a driving wheel rotatably supported by the rear arm, a drive motor supported by the frame structure or the rear arm, and an electric power generation unit supported by the frame body but not by the rear arm. The electric power generation unit includes: an electric power generation engine arranged with an offset toward a first direction from a center of the straddled vehicle with respect to a left-right direction, not overlapping the drive motor in a side view; and an electric power generator further in a second direction, opposite to the first direction, than the electric power generation engine, overlapping the electric power generation engine, but not overlapping the drive motor, in the side view. The electric power generator is driven by the electric power generation engine to generate electric power.

An in-case oil passage extending in an axial direction above a plurality of gears is formed inside an outer peripheral wall portion of the accommodating case. The in-case oil passage includes an in-case oil passage opening portion which opens from the cover wall portion to the one end side in the axial direction. The cover wall portion is provided with an oil guide member at a position where at least a part of the cover wall portion overlaps the in-case oil passage opening portion when viewed from the one end side in the axial direction, the oil guide member guiding oil discharged from the in-case oil passage opening portion to the oil collecting portion of the oil collecting pocket.

A shift fork shaft 123 has both end portions movably fitted in shaft supports 83e and 116a of a gear transmission 82. Clearances are left between bottom surfaces 83g and 116c of the shaft supports 83e and 116a and both end faces 123c of the shift fork shaft 123. Caps 145 are mounted in both axial ends of the shift fork shaft 123.

A transmission structure for a vehicle, the transmission structure including: a transmission having a plurality of speed change stages, the transmission including a speed change operation mechanism that has an output portion receiving an input motion produced by an actuator as an operation driving source and changing a speed change stage of the transmission, and a transmission case that houses the speed change operation mechanism, a part of the speed change operation mechanism being a torsion bar as a torque transmitting member, and a rear end gear being disposed on an end portion of the torsion bar; the transmission case including a boss portion holding an intermediate portion in an axial direction of the torsion bar.

A transmission case 210 supports a shift shaft 222 that constitutes a part of a speed change operation mechanism 220, and which receives an operating input and transmits a speed change motion of a transmission 201. A part of a transmission holder 162M in which part the shift shaft 222 is disposed includes a shaft insertion opening portion 162g that the shift shaft 222 is disposed so as to pass through.

A continuously variable transmission housing is provided that includes an inner cover and an outer cover connectable to the inner cover to define an interior chamber. The interior chamber is structured and operable to enclose a continuously variable transmission primary pulley, secondary pulley and pulley belt. The housing includes a duct panel mounted to the inner cover such that when the primary pulley is disposed within the interior chamber, the duct panel is disposed between an outer face of the primary pulley and the inner cover. Moreover, an air duct is defined between the inner cover and the duct panel, wherein the air duct is fluidly connected to ambient air from an ambient environment external to the housing. The duct panel includes a center opening that structured and operable to allow the ambient air to be drawn through the air duct and into the housing interior chamber.

A vehicle has an engine; a drive pulley connected to and driven by a crankshaft of the engine; a driven pulley; an output shaft connected to and driven by the driven pulley; a belt looped around the pulleys; and a cover connected to the engine. The cover and the engine define a volume therebetween. A baffle disposed in the volume separates the volume in first and second chambers. The first chamber is disposed between the baffle and the engine. The second chamber is disposed between the baffle and the cover. The pulleys are disposed in the second chamber. The baffle defines first and second apertures fluidly communicating the first chamber with the second chamber. An air inlet is fluidly connected to the first chamber. An air outlet is fluidly connected to the second chamber.

There is provided a lubricating structure for a power transmission mechanism in which a crankshaft is coupled to a piston disposed in a cylinder bore and in which power is transmitted from the crankshaft to a camshaft. The lubricating structure includes: an idler gear that is configured to transmit power from the crankshaft to the camshaft; and an idler gear shaft that supports the idler gear via a bearing. One end portion of the idler gear shaft protrudes into the cylinder bore, and an oil passage configured to guide oil from the cylinder bore to the bearing is formed in the idler gear shaft.

A two-wheeled vehicle is provided including a frame, front and rear ground-engaging members each supporting the frame, a straddle-type seat, a handlebar for steering the vehicle, at least one light device configured to operate in a hazard mode, an engine supported by the frame and operably coupled to the ground-engaging members, a tilt sensor, and a vehicle control unit in communication with the tilt sensor. The vehicle control unit is operative to detect a tilt angle of the vehicle based on output from the tilt sensor. The vehicle control unit is operative to determine a tip-over condition of the vehicle based on the detected tilt angle exceeding a threshold tilt angle. The vehicle control unit activates the hazard mode of the at least one light in response to the determination of the tip-over condition.

An off-highway recreational vehicle having a longitudinal centerline includes a frame and a rear suspension. The rear suspension includes a left A-arm, wherein the left A-arm has a pivot axis, the pivot axis being on a right-hand side of the longitudinal centerline.
