PURPOSE:To save space through reducing the weight of a vehicle body and the size of trim parts, by integrating an oil tank for a dry sump system lubricating device with a crankcase. CONSTITUTION:The oil tank which has been a separate body is integrated with the crankcase 1, and a passage 10a for communicating with an oil sump 7 side is formed as one body with a bottom 6 of the crankcase 1. Therefore, the weight of the oil tank is reduced, as compared to that in the case of providing the separate oil tank. In addition, since separate piping for the oil tank 12 is not required, the weight of the vehicle body can be largely reduced. Further, since the oil tank 12 is provided by utilizing a marginal space below a transmission case integral with the crankcase 1 and it is unnecessary to provide any separate piping for communicating the oil sump 7 to the oil tank 12, the engine is made to be extremely compact both as a single unit and in the condition of being fitted in a finished vehicle, and it can be contrived to lower the center of gravity of the engine. |
