ABSTRACT:
A valve actuating mechanism for an engine having a rocker arm movement restraining device which controls opening and closing an engine valve. The rocker arm movement restraining device includes a timing arm which engages left and right rocker arms for constraining the axial movement thereof, and a timing cam disposed on an intake-side camshaft. The rocker arm movement restraining device releases the engagement of the timing arm with the left and right rocker arms by activating the timing arm when the intake-side camshaft is rotated, and when the timing arm releases the engagement with the left and right rocker arms, the left and right rocker arms move to a predetermined operating position.
