摘要： Providing a rocker arm which can ensure the durability while reducing the inertial mass. The rocker arm (10) includes a valve abutment part (15) pressing a valve (80). The valve abutment part (15) includes a receiving wall (14) abutting against an end surface of a stem end (81A) of the valve (80) in a pressing state and a pair of sidewalls (13) protruding from both side ends (14A) of the receiving wall (14) so as to be opposed to each other and disposed along and in proximity to a side peripheral surface of the stem end (81A) of the valve (80). At least protruding distal ends of the sidewalls (13) each have a smaller thickness than adjacent portions and serve as a thinner portion (23).

摘要： The present invention provides a variable valve mechanism of an internal combustion engine, which includes a rocker arm that is driven by a cam so as to swing to drive a valve, a switching pin that is attached to the rocker arm so as to be shifted between a first position and a second position, a shift device that shifts the switching pin from the first position to the second position, and a return spring that returns the switching pin. In the variable valve mechanism, a drive state of the valve is switched by shifting the switching pin, the rocker arm is formed to have such a dimension that one end of the switching pin is exposed while projecting outward from the rocker arm, and the return spring is externally fitted to the one end of the switching pin so as to be exposed outside the rocker arm.

摘要： A damper structure for a gear device, which includes a first gear mounted to turn with respect to a shaft in a circumferential direction, a second gear mounted on the shaft to rotate integrally, a stopper rubber mounted on the second gear to face the first gear, and a pressing protrusion at the first gear to face the second gear. The stopper rubber is configured to be elastically deformed by pressing the pressing protrusion in a circumferential direction of the second gear during rotation of the first gear and be restored to the initial shape by separating the pressing protrusion during stop of the first gear. A recess for accumulating lubricating oil in the first gear is formed to face the stopper rubber.

摘要： A turbocharger includes a compressor housing including a scroll chamber, and a seal plate assembled to the compressor housing. The compressor housing and the seal plate define an intake passage. The seal plate includes a plate-side connecting portion in contact with the compressor housing. The radius of curvature of a wall surface of the scroll chamber of the compressor housing, in a section including a compressor rotational axis, is increased in a direction toward an outlet located on the downstream side of the scroll chamber in an intake air flow direction. The plate-side connecting portion protrudes in a direction along the compressor rotational axis. The radius of curvature of an inner surface of the seal plate continuous with the scroll chamber of the intake passage, in the section including the compressor rotational axis, is increased in the direction toward the outlet of the scroll chamber.

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.
