    摘要: To allow both the valve lift and valve timing for an engine valve to be varied in a continuous manner, the variable valve actuating device (1) comprises a camshaft (8) rotatably supported by a fixed part of the engine and provided with a cam (7), a first rocker arm (9) pivotally supported by a fixed part of the engine, the first rocker arm being provided with a first point (12) engaging a stem of an engine valve (6), a drum (11) rotatably supported by a fixed part of the engine and at least partly surrounding the cam, a second rocker arm (10) having a first point (20) pivotally supported by the drum, a second point (21) adapted to engage the cam and a surface engaged by a second point (22) of the first rocker arm, and a control member (25, 26) for selectively turning the drum over a prescribed angular range.

    摘要: A drive of a variable valve lift mechanism for driving a control shaft controlling a variable valve lift mechanism provided between an engine valve and an engine valve operating cam in order to change lift amount of the engine valve, comprises: a rotational force generating actuator; power conversion means for converting a rotational force of the rotational force generating actuator into a pivoting force of the control shaft; and a casing containing the power conversion means with the rotational force generating actuator coupled to an outer face of the casing. One end of the control shaft protrudes outward from one side of an engine body. The casing into which one end of the control shaft is inserted is attached to the one side of the engine body through fixing means which can be repeatedly attached and detached. Thus, it is possible to avoid the engine body from being complex and improve maintainability.
