摘要： A variable valve mechanism of an internal combustion engine includes a cam, a transmission mechanism, a first variable device that controls the transmission mechanism to continuously change at least a maximum lift amount of a lift curve indicating a lift amount of a valve that corresponds to a rotation angle of the internal combustion engine, and a second variable device that controls the transmission mechanism to continuously change at least an operation angle of the lift curve. When the lift curve lies in any condition within a predetermined range that covers all or part of a variable range of the lift curve, an absolute value of a ratio of a maximum lift amount variation to an operation angle variation for a slight change from the condition caused by the first variable device is larger than that for a slight change from the condition caused by the second variable device.

摘要： A variable valve mechanism includes a variable arm including a first arm and a second arm. The second arm is pivotally supported so as to be swingable by a support shaft. A position of the support shaft is a position where, during a base circle phase, in side view, a second segment connecting an axis of a roller to an axis of the support shaft is longer than a first segment connecting the axis of the roller to an axis of a camshaft, and an angle of the second segment formed with respect to a third segment connecting the axis of the roller to a swing axis of a roller arm is 60° to 120° toward the camshaft. The second arm extends from the support shaft such that a distal end portion of the second arm protrudes in between a cam and the roller.

摘要： In a variable valve mechanism of an internal combustion engine, when a slider is displaced relative to an input member and an output member in an axial direction, the output member turns relative to the input member in a swing direction, whereby a lift of a valve is increased or reduced. The variable valve mechanism is brought into a lift retaining state when the slider is placed in an idle running range located on a reducing direction side with respect to a boundary position. The lift retaining state is a state where when the slider is displaced in the axial direction, the input member and the output member are displaced together with the slider in the axial direction, so that the relative displacement of the slider and the relative turning of the output member do not occur and the lift of the valve is retained.
