たことを特徴とするエンジンの弁作動装置。 A cam that is rotationally driven in synchronization with the engine, a rocker arm that opens and closes the intake valve or the exhaust valve, a movable follower that is displaceable relative to the rocker arm, and a lost motion spring that presses the movable follower against the cam. A connecting pin that fits and slides between the locker arm and the movable follower, a return pin that can come into contact with one end of the locker arm and slides on the locker arm, and a return pin that connects the connecting pin to the movable follower via the return pin. A valve operating device for an engine comprising a return spring biasing the movable follower to the unrestrained position, and a connecting drive means for moving the coupling pin to the movable follower restraint position against the return spring, wherein the movable follower is in the unrestrained position. A valve operating device for an engine, characterized in that a locking means is provided for restricting sliding of the return pin so that the urging force of the return spring is not applied to the coupling pin via the return pin.
