Abstract
In a variable valve mechanism, during switching from a disconnected state to a connected state, the switch arm being displaced in a return direction comes in sliding contact with a pin end surface of the switch pin, and presses the pin end surface toward the disconnected position to push back the switch pin. At a sliding contact start time, the switch arm sliding contacts a portion of the pin end surface on a return direction side with respect to an idle-swing-side edge. At least during a period from a 10% position time to a sliding contact end time, a position of a pressed center relative to the pin end surface shifts toward the return direction side without stopping as the switch arm is displaced toward the return direction relative to a main arm, so that the sliding contact ends without stopping of the pressed center at a return-side edge.
