Abstract

A valve actuating mechanism for an internal combustion engine includes a first rocker arm moving mechanism, a second rocker arm moving mechanism, and a trigger arm. The first rocker arm moving mechanism moves left and right rocker arms from a first operation position side to a second operation position side. The second rocker arm moving mechanism moves the left and right rocker arms from the second operation position side to the first operation position side, and the trigger arm selectively restricts the movement of the left and right rocker arms. During engine operation, left and right rocker-side key portions of the left and right rocker arms, respectively, and left and right trigger-side key portions of the trigger arm selectively maintain or remove a restriction on the movement of the left and right rocker arms, in response to a rocking state of the left and right rocker arms.
