    摘要： A sliding bearing structure for a shaft member includes: a shaft member; a bearing member rotates relative to the shaft member; an oil supply space to which lubrication is supplied between sliding surfaces of the shaft member and the bearing member; two annular grooves formed in a circumferential direction in an inner peripheral surface of the bearing member; and two annular seal members formed as separate pieces from the shaft member and the bearing member, and arranged in the annular grooves between the shaft member and the bearing member. Each annular seal member is formed in plural, and is made of material having a thermal expansion coefficient such that an inside diameter of the annular seal member is smaller than an inside diameter of the bearing member at a low temperature, and is the same as or larger than the inside diameter of the bearing member at a high temperature.

    摘要： A sliding bearing 4 is constructed by an upper split bearing half 8 and a lower split bearing half 9. The upper split bearing half 8 has a sliding surface 8a, in which an oil groove 10 which allows an lubricating oil to flow therein is formed over the entire circumferential extent of the sliding surface 8a. The oil groove extends through a crush relief 8c to be open to a junction area 8b, and the oil groove has a bottom 10a which is formed so that a portion disposed toward the junction area as considered in the circumferential direction of the crush relief is located closer to the center of the upper split bearing half in comparison to a central portion. An ingress in large quantities of foreign particles within the oil groove onto the sliding surface of the sliding bearing and into a connecting rod bearing after passing through a lubricating oil feed passage is suppressed, and an oil leakage through the crush relief is reduced, allowing a lubricating oil pressure to be secured and augmented.

The upper split bearing half has a sliding surface, in which an oil groove which allows a lubricating oil to flow therein is formed over the entire circumferential extent of the sliding surfaced.

    摘要： An oil-feeding device for a crankshaft where the amount of lubricant oil leaking from supporting areas of main journal portions is reduced without increasing friction of bearing members against the main journal portions. The oil-feeding device for a crankshaft includes upper bearing members and lower bearing members. The upper and lower bearing members have a half hollow cylindrical shape, are provided with crush relief portions at both ends, and jointly encompass main journal portions of a crank shaft. The upper bearing members have circumferentially extending oil grooves provided in the faces opposite the main journal portions, the grooves penetrating through oil passages of a cylinder block. The lower bearing members do not have oil grooves. The oil grooves do not extend in the crush relief portions, and therefore the leakage of lubricant oil, fed to the oil grooves, to the areas of the crush relief portions is suppressed.
