摘要： A method of manufacturing a supporting structure includes disposing a supported member between a pair of opposed support walls, the support walls and the supported member having shaft holes formed coaxially through the support walls and the supported member respectively, inserting a shaft member through the shaft holes in the disposed state, the shaft member having two ends each having a peripheral portion circumferentially divided into a plurality of swaging portions continuous without discontinuity and swaging the swaging portions sequentially such that regions of the shaft member corresponding to the respective swaging portions are fixed in the shaft holes. The swaging portions include first swaging portions and second swaging portions, both of which are disposed so as to be paired at both radial sides of the shaft holes, respectively. A larger swage load is applied to each first swaging portion than to each second swaging portion.

摘要： A lubrication structure for a rocker arm includes a lash adjuster mounted in an accommodating portion located in an end of the rocker arm and a pushrod abutting against a lower end of the lash adjuster. The rocker arm is formed with an arm-inside oil supply passage for supplying lubrication oil to the lash adjuster. The lubrication oil guided into the accommodating portion is further guided through a through guide hole of the accommodating portion to an outer peripheral surface of the accommodating portion. The lubrication oil is further guided from an outer oil supply passage formed downwardly in the outer surface of the accommodating portion to the abutment between the lash adjuster and the pushrod.

摘要： The present invention provides a shim for a valve drive mechanism which is interposed between a pad surface of a rocker arm and a stem end surface of a valve. The shim includes a ship top surface that is contacted by the pad surface. The shim top surface is rotated about a center thereof to be cut, is provided with a center hole at the center thereof, and is shaped such that the pad surface does not contact an intersection line between an inner peripheral surface of the center hole and the shim top surface when the rocker arm is swung.

摘要： In a tappet with a built-in lash adjuster, hydraulic oil is prevented from leaking from a low pressure chamber during a long-period stop.A tappet (10) includes a hydraulic lash adjuster (11) which supports a lower end portion of a push rod (96) and a tappet case (12) to which the lash adjuster (11) is internally fitted and which is reciprocally displaced in a vertical direction according to a rotating cam (85). An inner peripheral surface of the tappet case (12) is provided with an air-vent passage (34) through which air existing between the tappet case (12) and the lash adjuster (11) can be discharged upward when the lash adjuster (11) is being assembled.
