Abstract
To reduce the size and weight of an oil tank for a dry sump type lubricating system. A separate oil tank of a dry sump type lubricating system is mounted on the front surface of a front case cover constituting part of a crankcase divided into front and rear parts. An effective volume portion, in which oil supplied from the crankcase side via scavenging pumps and cooled by an oil cooler is contained, is provided in the oil tank. The bottom portion of the effective volume portion is connected to a feed pump on the crankcase side via an outlet side passage. A tank side pipe portion extending rearwardly through the oil tank is integrally provided at a portion of the oil tank higher than the oil level in the oil tank. The tank side pipe portion is connected to a crankcase side pipe portion integrally provided on an upper portion of the front case cover to form an overflow passage. The overflow passage functions as a pressure-equalization passage for equalizing the pressure in the oil tank with the pressure in the crankcase, and allows overflowed oil in the oil tank to readily flow into the crankcase through the upper portion of the front case cover.
