Abstract
A valve operating device for an internal combustion engine having a drive rocker arm operatively associated with an intake or exhaust valve and a free rocker arm releasable from the intake or exhaust valve. The drive rocker arm and the free rocker arm are disposed adjacent to each other and operable selectively in mutually different modes according to the rotation of the camshaft. In one embodiment either the drive or free rocker arm has two arms connected together with one arm on each side of the other rocker arm for balanced loading. A selective coupling mechanism is disposed between the drive rocker arm and the free rocker arm for selectively connecting and disconnecting them with a coupling pin movable in a direction substantially normal to the axis of the rocker shaft.
