摘要： A torque shock or vibrations caused by the rotary inertia of a hydrostatic continuously variable transmission is reduced to improve ride quality of a vehicle when excessive torque occurs in a torque transmission path between a crankshaft and a drive wheel. A motorcycle includes a hydrostatic continuously variable transmission rotatably driven by torque of a crankshaft of an internal combustion engine. A rear wheel is rotatably driven by torque from the transmission. A torque damper absorbs excessive torque occurring in a torque transmission path from the crankshaft to the rear wheel. The torque dampers include an input side torque damper disposed in an input side torque transmission path between the crank shaft and the transmission and an output side torque damper disposed in an output side torque transmission path between the transmission and the rear wheel.

摘要： In an internal combustion engine, an oil-filler-port/oil-level-gauge attachment hole is formed on a side of the internal combustion engine. An oil-level-gauge for measuring the amount of oil in the inside of the internal combustion engine extends within the oil-filler-port. The oil-level-gauge is formed integral with a cap for the oil-filler-port. A guide cylinder portion for guiding the gauge deep inside the oil-level-gauge attachment hole is provided to extend therein. A side outflow hole where the filled oil detours around the guide cylinder portion and directly flows down to the inside is formed on the way of the guide cylinder portion. A guide wall for preventing the gauge from entering the side outflow hole is formed on a lower portion of the side outflow hole.

摘要： A valve train of an internal combustion engine having a swing of a link mechanism that is stabilized to stabilize the operating characteristics of an engine valve. A camshaft is provided together with a valve operating cam pivotally supported by the camshaft so as to operatively open and close an engine valve. A link mechanism allows a drive cam rotated integrally with the camshaft to swing the valve operating cam, and a drive mechanism swings the link mechanism, wherein opening and closing of the engine valve are started in a buffer section of the valve operating cam, and opening/closing timing of the engine valve is controlled by the drive mechanism swinging the valve operating cam via the link mechanism, without the provision of a buffer transition section and a buffer constant-speed section encountered at the time of transiting from a base circle to a cam lobe of the drive cam.
