摘要： A snowmobile, having an arrangement of components in which the layout of various accessory devices is improved for an internal combustion engine mounted thereon. A dry sump oil tank, a water pump and a starter motor are disposed in a concentrated space at a forward-facing portion of an internal combustion engine, which is mounted on a snowmobile at a position close to the front side of a body of the snowmobile. A steering shaft is arranged close to the front portion of the internal combustion engine, and is accommodated by modifying the shape of closely adjacent parts. Accordingly, the limited available space in a snowmobile is effectively used, and a rider riding in back of the engine can easily and closely approach the engine. The limited space inside the snowmobile cover is used effectively, by efficiently arranging selected accessory devices for an internal combustion engine mounted on the snowmobile.

摘要： A lubricating apparatus for an internal combustion engine is provided in which an oil discharge passage, extending from the oil pump, is provided for straddling the oil pump case and the tank body. A direction of the extension of the oil discharge passage is changed in the tank body such that the oil discharge passage further extends in parallel with a junction plane between the oil pump case and the tank body. An opening for pressure reception by a relief valve is provided in the oil discharge passage portion extending in parallel with the junction plane. By attaching the oil pump case such that an outside end portion of the relief valve is held by a portion of the oil pump case, the relief valve is fixed between the tank body and the oil pump case.
