    摘要： In a lash adjuster (A) of a valve gear which employs a serration-shaped thread mechanism, the formation of tribochemical reactive film is suppressed by using as the materials for its adjuster screw (15) and nut member (13) or the materials for their thread surfaces such materials that even if FM oil (friction modifier oil: motor oil containing organic molybdenum) is used, the friction coefficient will not extremely fall. The nut member is provided on the underside of an end plate (12) of a lifter body (11). The adjuster screw (15) is threadedly engaged in a threaded hole (14) of the nut member (13). The adjuster screw is biased by a return spring (16). The female threads of the threaded hole and the male threads of the adjuster screw are serration shaped. One or both of the nut member and the adjuster screw, or the pressured thread surfaces of one or both of them are formed of a material that will not react with oil additives of FM oil to suppress the formation of tribochemical reactive film, thereby stabilizing the operation of the lash adjuster.

    摘要： A gear comprised of a tooth surface and a hard carbon film formed on at least a part of the tooth surface. When the gear is used in lubricant including a specific component, a friction of a tooth surface of the gear is largely decreased, and therefore the gear performs an excellent power transmission efficiency. Further, when the gear is employed in a planetary gear mechanism or speed reducing mechanism which has a plurality of meshing portions of gears, the power transmission efficiency of the mechanism is also improved.

    摘要： A sliding structure is provided with at least a first sliding member that has a sliding surface and a plurality of micro-recessed parts with bottom surfaces having a maximum depth point spaced from the sliding surface to define a plurality of recesses. Each bottom surfaces includes a concaved portion extending rearward with respect to a sliding direction from the maximum depth point. Each micro-recessed part has a cross-sectional shape in the sliding direction having an S/L ratio of 0 to 0.3, where L is an overall length of the micro-recessed part with respect to the sliding surface in the sliding direction and S is a length from a forward edge of the micro-recessed part with respect to the sliding surface in the sliding direction to the maximum depth point. The sliding member slide with respect to another sliding member with a viscous fluid interposed therebetween.
