    • PROBLEM TO BE SOLVED: To provide a member for a valve drive system for an internal combustion engine, such as a valve lifter and a shim, which provides low friction and exerts steady slidability.SOLUTION: The member for a valve drive system for the internal combustion engine consists of a cam follower having a slide contact surface that is in slide-contact with a cam surface of a cam to follow the cam under a wet process condition where a lubricating oil lies. The slide contact surface of the cam follower is coated by a DLC film (DLC-B film) that consists of 5-25 atom% of H, 4-25 atom% of B, and the remainder of C when assuming the whole as 100 atom%. The slide contact surface that consists of the DLC-B film has high toughness and excellent impact resistance, and causes no lack, etc., even if received an impact force of 150-250 MPa/deg from the cam surface. Moreover, the cam follower exerts an excellent low friction coefficient when used under the wet process condition where the lubricating oil not containing molybdenum dialkyl dithiocarbamate (MoDTC) lies.

    • 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.

    • 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.
