摘要： PROBLEM TO BE SOLVED: To prevent the occurrence of abnormal wear on a sliding face of a pivot part that rockably supports one end of a rocker arm. SOLUTION: In this valve gear mechanism, in the pivot part, a spherical recessed and curved surface 10c of a rocking member 10 provided at one end of the rocker arm 3 slides with respect to a spherical protruded and curved surface 14c of a hydraulic adjuster member 14 for supporting the one end of the rocker arm 3. An affinity promoting surface layer 13 having a hardness lower than those of the spherical recessed and curved surface 10c and the spherical protruded and curved surface 14c is provided on the spherical recessed and curved surface 10c of the rocking member 10. As sliding of the affinity promoting surface layer 13 is repeated with respect to the spherical protruded and curved surface 14c, affinity of the affinity promoting surface layer 13 is promoted, its surface roughness is reduced, and the clearance between the affinity promoting surface layer 13 and the spherical protruded and curved surface 14c can be made narrow, so that intrusion of an aggregate of carbon soot of a harmful size can be prevented from intruding in the clearance.

摘要： PROBLEM TO BE SOLVED: To promote a rise of a temperature of lubrication oil at a low temperature, and to promote the lubrication of the lubrication oil at a high temperature when supporting a rotating shaft by a radial plain bearing using the lubrication oil.SOLUTION: In a back plate 32, a coefficient of thermal expansion of a back plate layer 35 at an internal peripheral side which is high in a coefficient of thermal expansion is higher than a coefficient of thermal expansion of a back plate layer 34 at an external peripheral side which is low in a coefficient of thermal expansion. An oil relief 36 is narrowed at a low temperature, thereby the discharge of the lubrication oil filled between a crank pin 18 and a bearing alloy layer 33 is suppressed. Alternatively, the oil relief 36 is widened by the thermal expansion of the pack plate 32 at which an amount of the thermal expansion of the back metal layer 35 at the internal peripheral side which is high in a coefficient of thermal expansion becomes larger than an amount of the thermal expansion of the back plate layer 34 at the external peripheral side which is low in a coefficient of thermal expansion, and thus the discharge of the lubrication oil filled between the crank pin 18 and the bearing alloy layer 33 is promoted.
