Claims

[Scope of Claim for Utility Model Registration] A separate external oil tank is provided outside the engine body, and lubricating oil is transferred from the oil pan at the bottom of the crank chamber to the external oil tank and stored therein, and the external oil In a lubrication system that leads lubricating oil from a tank to an engine oil supply pump and circulates it inside the engine, the external oil tank is formed by an inner cylinder and an outer cylinder that are made of a cylindrical body, forming an oil reservoir space between the inner and outer cylinders. The lubricating oil flowing into the inner cylinder is configured to have a cylindrical shape, and an inlet oil passage communicating with the suction pump is connected and opened in the tangential direction of the peripheral wall of the inner cylinder to impart a swirling flow to the lubricating oil flowing into the inner cylinder, and A dry sump type lubricating device characterized in that a communication port communicating with an oil reservoir space is opened at the bottom of an inner cylinder, and an outlet oil passage communicating with a suction port of an engine oil supply pump is connected to the bottom of the oil reservoir space.
