    Abstract: In an outboard motor, a feed passage, through which a lubricating oil that flows upward from a gear mechanism due to rotation of the gear mechanism is fed upward from a gear chamber, includes a first feed passage, extending from the gear chamber to a connection passage via a first upstream passage, a spiral passage, and an interior of an upper bearing, in that order, and a second feed passage, extending from the first upstream passage to the connection passage while bypassing the spiral passage via a bypass passage. The bypass passage is positioned farther outward than the spiral passage in a radial direction of the driveshaft. A diameter of a cross section of the bypass passage that is orthogonal or substantially orthogonal to a center line of the driveshaft is smaller than a maximum diameter of the driveshaft.

    Abstract: A motorcycle includes a cylinder body, a cylinder head disposed above the cylinder body, and a plurality of dowel pins configured to position the cylinder body and the cylinder head. The cylinder body includes a plurality of cylinders and a plurality of bolt insertion holes. The cylinder head includes first and second passages configured to flow oil or air therethrough. The cylinder body includes a first communication port in communication with the first passage and a second communication port in communication with the second passage. The first communication port is disposed in a front left region, and the second communication port is disposed in a rear right region. The plurality of dowel pins consist of a first dowel pin fitted into the first communication port and the first passage and a second dowel pin fitted into the second communication port and the second passage.

    Abstract: A first aspect of an oil distributing structure for an internal combustion engine includes a bearing support wall including a plurality of guide ribs which are radially mounted on a surface thereof. The guide ribs may be integrally formed, and extend around an upper half of the bearing, for collecting oil which is splashed onto, and flows down the wall surface. In a second aspect of an oil distributing structure for an internal combustion engine, a slanted edge portion, descending toward the bearing, is formed on the bearing support wall, and is disposed laterally of a lower portion of the bearing. The described structure is useful for collecting oil splashed onto a wall surface of a crankcase, and for supplying the collected oil to a bearing in an internal combustion engine of the type in which a crankshaft bearing is supplied with oil splashed from nearby gears.
